Apache Camel Component Reference

Chapter 1. Components Overview
复制链接

This chapter provides a summary of all the components available for Apache Camel.

1.1. Container types
复制链接

Red Hat Fuse provides a variety of container types, into which you can deploy your Camel applications:

Spring Boot
Apache Karaf
JBoss Enterprise Application Platform (JBoss EAP)

In addition, a Camel application can run as containerless: that is, where a Camel application runs directly in the JVM, without any special container.

In some cases, Fuse might support a Camel component in one container, but not in the others. There are various reasons for this, but in some cases a component is not suitable for all container types. For example, the camel-ejb component is designed spcifically for Java EE (that is, JBoss EAP), and cannot be supported in the other container types.

Chapter 2. ActiveMQ
复制链接

ActiveMQ Component
复制链接

The ActiveMQ component allows messages to be sent to a JMS Queue or Topic; or messages to be consumed from a JMS Queue or Topic using Apache ActiveMQ.

This component is based on the Chapter 178, JMS Component and uses Spring’s JMS support for declarative transactions, using Spring’s JmsTemplate for sending and a MessageListenerContainer for consuming. All the options from the Chapter 178, JMS Component component also apply for this component.

To use this component, make sure you have the activemq.jar or activemq-core.jar on your classpath along with any Apache Camel dependencies such as camel-core.jar, camel-spring.jar and camel-jms.jar.

Transacted and caching

See section Transactions and Cache Levels below on JMS page if you are using transactions with JMS as it can impact performance.

URI format

activemq:[queue:|topic:]destinationName

activemq:[queue:|topic:]destinationName

Copy to Clipboard

Toggle word wrap

Where destinationName is an ActiveMQ queue or topic name. By default, the destinationName is interpreted as a queue name. For example, to connect to the queue, FOO.BAR, use:

activemq:FOO.BAR

activemq:FOO.BAR

Copy to Clipboard

Toggle word wrap

You can include the optional queue: prefix, if you prefer:

activemq:queue:FOO.BAR

activemq:queue:FOO.BAR

Copy to Clipboard

Toggle word wrap

To connect to a topic, you must include the topic: prefix. For example, to connect to the topic, Stocks.Prices, use:

activemq:topic:Stocks.Prices

activemq:topic:Stocks.Prices

Options

See Options on the Chapter 178, JMS Component component as all these options also apply for this component.

Camel on EAP deployment
复制链接

This component is supported by the Camel on EAP (Wildfly Camel) framework, which offers a simplified deployment model on the Red Hat JBoss Enterprise Application Platform (JBoss EAP) container.

You can configure the ActiveMQ Camel component to work either with an embedded broker or an external broker. To embed a broker in the JBoss EAP container, configure the ActiveMQ Resource Adapter in the EAP container configuration file — for details, see ActiveMQ Resource Adapter Configuration.

Configuring the Connection Factory
复制链接

The following test case shows how to add an ActiveMQComponent to the CamelContext using the activeMQComponent() method while specifying the brokerURL used to connect to ActiveMQ.

camelContext.addComponent("activemq", activeMQComponent("vm://localhost?broker.persistent=false"));

camelContext.addComponent("activemq", activeMQComponent("vm://localhost?broker.persistent=false"));

You can configure the ActiveMQ broker URL on the ActiveMQComponent as follows

Using connection pooling
复制链接

When sending to an ActiveMQ broker using Camel it’s recommended to use a pooled connection factory to handle efficient pooling of JMS connections, sessions and producers. This is documented in the page ActiveMQ Spring Support.

You can grab Jencks AMQ pool with Maven:

    <dependency>
      <groupId>org.apache.activemq</groupId>
      <artifactId>activemq-pool</artifactId>
      <version>5.3.2</version>
    </dependency>

      <artifactId>activemq-pool</artifactId>
      <version>5.3.2</version>
    </dependency>

And then setup the activemq component as follows:

    <bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://localhost:61616" />
    </bean>

    <bean id="pooledConnectionFactory"    class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">

Note

Notice the init and destroy methods on the pooled connection factory. This is important to ensure the connection pool is properly started and shutdown.

The PooledConnectionFactory will then create a connection pool with up to 8 connections in use at the same time. Each connection can be shared by many sessions. There is an option named maxActive you can use to configure the maximum number of sessions per connection; the default value is 500. From ActiveMQ 5.7 onwards the option has been renamed to better reflect its purpose, being named as maxActiveSessionPerConnection. Notice the concurrentConsumers is set to a higher value than maxConnections is. This is okay, as each consumer is using a session, and as a session can share the same connection, we are in the safe. In this example we can have 8 * 500 = 4000 active sessions at the same time.

Invoking MessageListener POJOs in a route
复制链接

The ActiveMQ component also provides a helper Type Converter from a JMS MessageListener to a Processor. This means that the Chapter 43, Bean Component component is capable of invoking any JMS MessageListener bean directly inside any route.

So for example you can create a MessageListener in JMS as follows:

public class MyListener implements MessageListener {
   public void onMessage(Message jmsMessage) {
       // ...
   }
}

public class MyListener implements MessageListener {
   public void onMessage(Message jmsMessage) {
       // ...
   }
}

Then use it in your route as follows

from("file://foo/bar").
  bean(MyListener.class);

from("file://foo/bar").
  bean(MyListener.class);

That is, you can reuse any of the Apache Camel components and easily integrate them into your JMS MessageListener POJO\!

Using ActiveMQ Destination Options
复制链接

Available as of ActiveMQ 5.6

You can configure the Destination Options in the endpoint uri, using the "destination." prefix. For example to mark a consumer as exclusive, and set its prefetch size to 50, you can do as follows:

<camelContext xmlns="http://camel.apache.org/schema/spring">
  <route>
    <from uri="file://src/test/data?noop=true"/>
    <to uri="activemq:queue:foo"/>
  </route>
  <route>
    <!-- use consumer.exclusive ActiveMQ destination option, notice we have to prefix with destination. -->
    <from uri="activemq:foo?destination.consumer.exclusive=true&amp;destination.consumer.prefetchSize=50"/>
    <to uri="mock:results"/>
  </route>
</camelContext>

<camelContext xmlns="http://camel.apache.org/schema/spring">

Consuming Advisory Messages
复制链接

ActiveMQ can generate Advisory messages which are put in topics that you can consume. Such messages can help you send alerts in case you detect slow consumers or to build statistics (number of messages/produced per day, etc.) The following Spring DSL example shows you how to read messages from a topic.

<route>
	<from uri="activemq:topic:ActiveMQ.Advisory.Connection?mapJmsMessage=false" />
	<convertBodyTo type="java.lang.String"/>
	<transform>
	     <simple>${in.body}&#13;</simple>
	</transform>
	<to uri="file://data/activemq/?fileExist=Append&ileName=advisoryConnection-${date:now:yyyyMMdd}.txt" />
</route>

bridgeEndpoint (producer)	If the option is true, then the Exchange.HTTP_URI header is ignored, and use the endpoint’s URI for request. You may also set the throwExceptionOnFailure to be false to let the AhcProducer send all the fault response back.	false	boolean
bufferSize (producer)	The initial in-memory buffer size used when transferring data between Camel and AHC Client.	4096	int
connectionClose (producer)	Define if the Connection Close header has to be added to HTTP Request. This parameter is false by default	false	boolean
cookieHandler (producer)	Configure a cookie handler to maintain a HTTP session		CookieHandler
headerFilterStrategy (producer)	To use a custom HeaderFilterStrategy to filter header to and from Camel message.		HeaderFilterStrategy
throwExceptionOnFailure (producer)	Option to disable throwing the AhcOperationFailedException in case of failed responses from the remote server. This allows you to get all responses regardless of the HTTP status code.	true	boolean
transferException (producer)	If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a application/x-java-serialized-object content type (for example using Jetty or Servlet Camel components). On the producer side the exception will be deserialized and thrown as is, instead of the AhcOperationFailedException. The caused exception is required to be serialized. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.	false	boolean

`Exchange.HTTP_QUERY`	`String`	Camel 2.11 onwards: URI parameters. Will override existing URI parameters set directly on the endpoint.
`Exchange.HTTP_RESPONSE_CODE`	`int`	The HTTP response code from the external server. Is 200 for OK.
`Exchange.HTTP_CHARACTER_ENCODING`	`String`	Character encoding.
`Exchange.CONTENT_TYPE`	`String`	The HTTP content type. Is set on both the IN and OUT message to provide a content type, such as `text/html`.
`Exchange.CONTENT_ENCODING`	`String`	The HTTP content encoding. Is set on both the IN and OUT message to provide a content encoding, such as `gzip`.

3.5. Message Body
复制链接

Camel will store the HTTP response from the external server on the OUT body. All headers from the IN message will be copied to the OUT message, so headers are preserved during routing. Additionally Camel will add the HTTP response headers as well to the OUT message headers.

3.6. Response code
复制链接

Camel will handle according to the HTTP response code:

Response code is in the range 100..299, Camel regards it as a success response.
Response code is in the range 300..399, Camel regards it as a redirection response and will throw a AhcOperationFailedException with the information.
Response code is 400+, Camel regards it as an external server failure and will throw a AhcOperationFailedException with the information.
throwExceptionOnFailure
The option, throwExceptionOnFailure, can be set to false to prevent the AhcOperationFailedException from being thrown for failed response codes. This allows you to get any response from the remote server.

3.7. AhcOperationFailedException
复制链接

This exception contains the following information:

The HTTP status code
The HTTP status line (text of the status code)
Redirect location, if server returned a redirect
Response body as a java.lang.String, if server provided a body as response

3.8. Calling using GET or POST
复制链接

The following algorithm is used to determine if either GET or POST HTTP method should be used:
1. Use method provided in header.
2. GET if query string is provided in header.
3. GET if endpoint is configured with a query string.
4. POST if there is data to send (body is not null).
5. GET otherwise.

3.9. Configuring URI to call

3.13. Configuring AsyncHttpClient
复制链接

The AsyncHttpClient client uses a AsyncHttpClientConfig to configure the client. See the documentation at
Async Http Client for more details.

In Camel 2.8, configuration is limited to using the builder pattern provided by AsyncHttpClientConfig.Builder. In Camel 2.8, the AsyncHttpClientConfig doesn’t support getters/setters so its not easy to create/configure using a Spring bean style (eg the <bean> tag in the XML file).

The example below shows how to use a builder to create the AsyncHttpClientConfig which we configure on the AhcComponent.

In Camel 2.9, the AHC component uses Async HTTP library 1.6.4. This newer version provides added support for plain bean style configuration. The AsyncHttpClientConfigBean class provides getters and setters for the configuration options available in AsyncHttpClientConfig. An instance of AsyncHttpClientConfigBean may be passed directly to the AHC component or referenced in an endpoint URI using the clientConfig URI parameter.

Also available in Camel 2.9 is the ability to set configuration options directly in the URI. URI parameters starting with "clientConfig." can be used to set the various configurable properties of AsyncHttpClientConfig. The properties specified in the endpoint URI are merged with those specified in the configuration referenced by the "clientConfig" URI parameter with those being set using the "clientConfig." parameter taking priority. The AsyncHttpClientConfig instance referenced is always copied for each endpoint such that settings on one endpoint will remain independent of settings on any previously created endpoints. The example below shows how to configure the AHC component using the "clientConfig." type URI parameters.

from("direct:start")
    .to("ahc:http://localhost:8080/foo?clientConfig.maxRequestRetry=3&clientConfig.followRedirects=true")

from("direct:start")
    .to("ahc:http://localhost:8080/foo?clientConfig.maxRequestRetry=3&clientConfig.followRedirects=true")

3.14. SSL Support (HTTPS)
复制链接

Using the JSSE Configuration Utility

As of Camel 2.9, the AHC component supports SSL/TLS configuration through the Camel JSSE Configuration Utility. This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels. The following examples demonstrate how to use the utility with the AHC component.

Programmatic configuration of the component

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

SSLContextParameters scp = new SSLContextParameters();
scp.setKeyManagers(kmp);

AhcComponent component = context.getComponent("ahc", AhcComponent.class);
component.setSslContextParameters(scp));

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

SSLContextParameters scp = new SSLContextParameters();
scp.setKeyManagers(kmp);

AhcComponent component = context.getComponent("ahc", AhcComponent.class);
component.setSslContextParameters(scp));

Chapter 4. AHC Websocket Component
复制链接

Available as of Camel version 2.14

The ahc-ws component provides Websocket based endpoints for a client communicating with external servers over Websocket (as a client opening a websocket connection to an external server).
The component uses the AHC component that in turn uses the Async Http Client library.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-ahc-ws</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

sslContextParameters (security)	Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. Note that configuring this option will override any SSL/TLS configuration options provided through the clientConfig option at the endpoint or component level.		SSLContextParameters
allowJavaSerialized Object (advanced)	Whether to allow java serialization when a request uses context-type=application/x-java-serialized-object This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.	false	boolean
useGlobalSslContext Parameters (security)	Enable usage of global SSL context parameters.	false	boolean
headerFilterStrategy (filter)	To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message.		HeaderFilterStrategy

On the producer side the exception will be deserialized and thrown as is, instead of the AhcOperationFailedException. The caused exception is required to be serialized. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.	false	boolean
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler.

clientConfigRealmOptions (security)	To configure the AsyncHttpClientConfig Realm using the key/values from the Map.		Map
sslContextParameters (security)	Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. This reference overrides any configured SSLContextParameters at the component level. See Using the JSSE Configuration Utility. Note that configuring this option will override any SSL/TLS configuration options provided through the clientConfig option at the endpoint or component level.		SSLContextParameters

4.3. Writing and Reading Data over Websocket

Chapter 5. AMQP Component
复制链接

Available as of Camel version 1.2

The amqp: component supports the AMQP 1.0 protocol using the JMS Client API of the Qpid project. In case you want to use AMQP 0.9 (in particular RabbitMQ) you might also be interested in the Camel RabbitMQ component. Please keep in mind that prior to the Camel 2.17.0 AMQP component supported AMQP 0.9 and above, however since Camel 2.17.0 it supports only AMQP 1.0.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-amqp</artifactId>
    <version>${camel.version}</version> <!-- use the same version as your Camel core version -->

You can specify all of the various configuration options of the JMS component after the destination name.

The AMQP component supports 80 options which are listed below.

Expand

Name	Description	Default	Type
configuration (advanced)	To use a shared JMS configuration		JmsConfiguration
acceptMessagesWhile Stopping (consumer)	Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.	false	boolean
allowReplyManagerQuick Stop (consumer)	Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfigurationisAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.	false	boolean
acknowledgementMode (consumer)	The JMS acknowledgement mode defined as an Integer. Allows you to set vendor-specific extensions to the acknowledgment mode.For the regular modes, it is preferable to use the acknowledgementModeName instead.		int
eagerLoadingOf Properties (consumer)	Enables eager loading of JMS properties as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties	false	boolean
acknowledgementModeName (consumer)	The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE	AUTO_ ACKNOWLEDGE	String
autoStartup (consumer)	Specifies whether the consumer container should auto-startup.	true	boolean
cacheLevel (consumer)	Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details.		int
cacheLevelName (consumer)	Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.	CACHE_AUTO	String
replyToCacheLevelName (producer)	Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.		String
clientId (common)	Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead.		String
concurrentConsumers (consumer)	Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.	1	int
replyToConcurrent Consumers (producer)	Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.	1	int
connectionFactory (common)	The connection factory to be use. A connection factory must be configured either on the component or endpoint.		ConnectionFactory
username (security)	Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.		String
password (security)	Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.		String
deliveryPersistent (producer)	Specifies whether persistent delivery is used by default.	true	boolean
deliveryMode (producer)	Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.		Integer
durableSubscriptionName (common)	The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well.		String
exceptionListener (advanced)	Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions.		ExceptionListener
errorHandler (advanced)	Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler.		ErrorHandler
errorHandlerLogging Level (logging)	Allows to configure the default errorHandler logging level for logging uncaught exceptions.	WARN	LoggingLevel
errorHandlerLogStack Trace (logging)	Allows to control whether stacktraces should be logged or not, by the default errorHandler.	true	boolean
explicitQosEnabled (producer)	Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers.	false	boolean
exposeListenerSession (consumer)	Specifies whether the listener session should be exposed when consuming messages.	false	boolean
idleTaskExecutionLimit (advanced)	Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.	1	int
idleConsumerLimit (advanced)	Specify the limit for the number of consumers that are allowed to be idle at any given time.	1	int
maxConcurrentConsumers (consumer)	Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.		int
replyToMaxConcurrent Consumers (producer)	Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.		int
replyOnTimeoutToMax ConcurrentConsumers (producer)	Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.	1	int
maxMessagesPerTask (advanced)	The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.	-1	int
messageConverter (advanced)	To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message.		MessageConverter
mapJmsMessage (advanced)	Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc.	true	boolean
messageIdEnabled (advanced)	When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value	true	boolean
messageTimestampEnabled (advanced)	Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value	true	boolean
alwaysCopyMessage (producer)	If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set)	false	boolean
useMessageIDAs CorrelationID (advanced)	Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.	false	boolean
priority (producer)	Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.	4	int
pubSubNoLocal (advanced)	Specifies whether to inhibit the delivery of messages published by its own connection.	false	boolean
receiveTimeout (advanced)	The timeout for receiving messages (in milliseconds).	1000	long
recoveryInterval (advanced)	Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds.	5000	long
taskExecutor (consumer)	Allows you to specify a custom task executor for consuming messages.		TaskExecutor
timeToLive (producer)	When sending messages, specifies the time-to-live of the message (in milliseconds).	-1	long
transacted (transaction)	Specifies whether to use transacted mode	false	boolean
lazyCreateTransaction Manager (transaction)	If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true.	true	boolean
transactionManager (transaction)	The Spring transaction manager to use.		PlatformTransaction Manager
transactionName (transaction)	The name of the transaction to use.		String
transactionTimeout (transaction)	The timeout value of the transaction (in seconds), if using transacted mode.	-1	int
testConnectionOn Startup (common)	Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well.	false	boolean
asyncStartListener (advanced)	Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry.	false	boolean
asyncStopListener (advanced)	Whether to stop the JmsConsumer message listener asynchronously, when stopping a route.	false	boolean
forceSendOriginal Message (producer)	When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.	false	boolean
requestTimeout (producer)	The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option.	20000	long
requestTimeoutChecker Interval (advanced)	Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout.	1000	long
transferExchange (advanced)	You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload.	false	boolean
transferException (advanced)	If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer.	false	boolean
transferFault (advanced)	If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on MessageisFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstantsJMS_TRANSFER_FAULTJMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the link org.apache.camel.MessagesetFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws.	false	boolean
jmsOperations (advanced)	Allows you to use your own implementation of the org.springframework.jms.core.JmsOperations interface. Camel uses JmsTemplate as default. Can be used for testing purpose, but not used much as stated in the spring API docs.		JmsOperations
destinationResolver (advanced)	A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry).		DestinationResolver
replyToType (producer)	Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.		ReplyToType
preserveMessageQos (producer)	Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header.	false	boolean
asyncConsumer (consumer)	Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions).	false	boolean
allowNullBody (producer)	Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown.	true	boolean
includeSentJMS MessageID (producer)	Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.	false	boolean
includeAllJMSX Properties (advanced)	Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.	false	boolean
defaultTaskExecutor Type (consumer)	Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers.		DefaultTaskExecutor Type
jmsKeyFormatStrategy (advanced)	Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the notation.		JmsKeyFormatStrategy
allowAdditionalHeaders (producer)	This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching.		String
queueBrowseStrategy (advanced)	To use a custom QueueBrowseStrategy when browsing queues		QueueBrowseStrategy
messageCreatedStrategy (advanced)	To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message.		MessageCreatedStrategy
waitForProvision CorrelationToBeUpdated Counter (advanced)	Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled.	50	int
waitForProvision CorrelationToBeUpdated ThreadSleepingTime (advanced)	Interval in millis to sleep each time while waiting for provisional correlation id to be updated.	100	long
correlationProperty (producer)	Use this JMS property to correlate messages in InOut exchange pattern (request-reply) instead of JMSCorrelationID property. This allows you to exchange messages with systems that do not correlate messages using JMSCorrelationID JMS property. If used JMSCorrelationID will not be used or set by Camel. The value of here named property will be generated if not supplied in the header of the message under the same name.		String
subscriptionDurable (consumer)	Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well.	false	boolean
subscriptionShared (consumer)	Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker.	false	boolean
subscriptionName (consumer)	Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).		String
streamMessageType Enabled (producer)	Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data.	false	boolean
formatDateHeadersTo Iso8601 (producer)	Sets whether date headers should be formatted according to the ISO 8601 standard.	false	boolean
headerFilterStrategy (filter)	To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message.		HeaderFilterStrategy
resolveProperty Placeholders (advanced)	Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders.	true	boolean

复制链接

Expand

Name	Description	Default	Type
clientId (common)	Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead.		String
connectionFactory (common)	The connection factory to be use. A connection factory must be configured either on the component or endpoint.		ConnectionFactory
disableReplyTo (common)	Specifies whether Camel ignores the JMSReplyTo header in messages. If true, Camel does not send a reply back to the destination specified in the JMSReplyTo header. You can use this option if you want Camel to consume from a route and you do not want Camel to automatically send back a reply message because another component in your code handles the reply message. You can also use this option if you want to use Camel as a proxy between different message brokers and you want to route message from one system to another.	false	boolean
durableSubscriptionName (common)	The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well.		String
jmsMessageType (common)	Allows you to force the use of a specific javax.jms.Message implementation for sending JMS messages. Possible values are: Bytes, Map, Object, Stream, Text. By default, Camel would determine which JMS message type to use from the In body type. This option allows you to specify it.		JmsMessageType
testConnectionOnStartup (common)	Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well.	false	boolean
acknowledgementModeName (consumer)	The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE	AUTO_ ACKNOWLEDGE	String
asyncConsumer (consumer)	Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions).	false	boolean
autoStartup (consumer)	Specifies whether the consumer container should auto-startup.	true	boolean
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
cacheLevel (consumer)	Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details.		int
cacheLevelName (consumer)	Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.	CACHE_AUTO	String
concurrentConsumers (consumer)	Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.	1	int
maxConcurrentConsumers (consumer)	Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.		int
replyTo (consumer)	Provides an explicit ReplyTo destination, which overrides any incoming value of Message.getJMSReplyTo().		String
replyToDeliveryPersistent (consumer)	Specifies whether to use persistent delivery by default for replies.	true	boolean
selector (consumer)	Sets the JMS selector to use		String
subscriptionDurable (consumer)	Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well.	false	boolean
subscriptionName (consumer)	Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).		String
subscriptionShared (consumer)	Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker.	false	boolean
acceptMessagesWhileStopping (consumer)	Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.	false	boolean
allowReplyManagerQuickStop (consumer)	Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfigurationisAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.	false	boolean
consumerType (consumer)	The consumer type to use, which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.	Default	ConsumerType
defaultTaskExecutorType (consumer)	Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers.		DefaultTaskExecutor Type
eagerLoadingOfProperties (consumer)	Enables eager loading of JMS properties and payload as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties	false	boolean
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange.		ExchangePattern
exposeListenerSession (consumer)	Specifies whether the listener session should be exposed when consuming messages.	false	boolean
replyToSameDestination Allowed (consumer)	Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself.	false	boolean
taskExecutor (consumer)	Allows you to specify a custom task executor for consuming messages.		TaskExecutor
deliveryMode (producer)	Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.		Integer
deliveryPersistent (producer)	Specifies whether persistent delivery is used by default.	true	boolean
explicitQosEnabled (producer)	Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers.	false	Boolean
formatDateHeadersToIso8601 (producer)	Sets whether JMS date properties should be formatted according to the ISO 8601 standard.	false	boolean
preserveMessageQos (producer)	Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header.	false	boolean
priority (producer)	Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.	4	int
replyToConcurrentConsumers (producer)	Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.	1	int
replyToMaxConcurrent Consumers (producer)	Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.		int
replyToOnTimeoutMax ConcurrentConsumers (producer)	Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.	1	int
replyToOverride (producer)	Provides an explicit ReplyTo destination in the JMS message, which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination.		String
replyToType (producer)	Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.		ReplyToType
requestTimeout (producer)	The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option.	20000	long
timeToLive (producer)	When sending messages, specifies the time-to-live of the message (in milliseconds).	-1	long
allowAdditionalHeaders (producer)	This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching.		String
allowNullBody (producer)	Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown.	true	boolean
alwaysCopyMessage (producer)	If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set)	false	boolean
correlationProperty (producer)	When using InOut exchange pattern use this JMS property instead of JMSCorrelationID JMS property to correlate messages. If set messages will be correlated solely on the value of this property JMSCorrelationID property will be ignored and not set by Camel.		String
disableTimeToLive (producer)	Use this option to force disabling time to live. For example when you do request/reply over JMS, then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized, so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details.	false	boolean
forceSendOriginalMessage (producer)	When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.	false	boolean
includeSentJMSMessageID (producer)	Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.	false	boolean
replyToCacheLevelName (producer)	Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.		String
replyToDestinationSelector Name (producer)	Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is, if you are not using a temporary reply queue).		String
streamMessageTypeEnabled (producer)	Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data.	false	boolean
allowSerializedHeaders (advanced)	Controls whether or not to include serialized headers. Applies only when transferExchange is true. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level.	false	boolean
asyncStartListener (advanced)	Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry.	false	boolean
asyncStopListener (advanced)	Whether to stop the JmsConsumer message listener asynchronously, when stopping a route.	false	boolean
destinationResolver (advanced)	A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry).		DestinationResolver
errorHandler (advanced)	Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler.		ErrorHandler
exceptionListener (advanced)	Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions.		ExceptionListener
headerFilterStrategy (advanced)	To use a custom HeaderFilterStrategy to filter header to and from Camel message.		HeaderFilterStrategy
idleConsumerLimit (advanced)	Specify the limit for the number of consumers that are allowed to be idle at any given time.	1	int
idleTaskExecutionLimit (advanced)	Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.	1	int
includeAllJMSXProperties (advanced)	Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.	false	boolean
jmsKeyFormatStrategy (advanced)	Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the notation.		String
mapJmsMessage (advanced)	Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc.	true	boolean
maxMessagesPerTask (advanced)	The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.	-1	int
messageConverter (advanced)	To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message.		MessageConverter
messageCreatedStrategy (advanced)	To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message.		MessageCreatedStrategy
messageIdEnabled (advanced)	When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value	true	boolean
messageListenerContainer Factory (advanced)	Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom.		MessageListener ContainerFactory
messageTimestampEnabled (advanced)	Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value	true	boolean
pubSubNoLocal (advanced)	Specifies whether to inhibit the delivery of messages published by its own connection.	false	boolean
receiveTimeout (advanced)	The timeout for receiving messages (in milliseconds).	1000	long
recoveryInterval (advanced)	Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds.	5000	long
requestTimeoutChecker Interval (advanced)	Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout.	1000	long
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean
transferException (advanced)	If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer.	false	boolean
transferExchange (advanced)	You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload.	false	boolean
transferFault (advanced)	If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on MessageisFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstantsJMS_TRANSFER_FAULTJMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the link org.apache.camel.MessagesetFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws.	false	boolean
useMessageIDAsCorrelation ID (advanced)	Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.	false	boolean
waitForProvisionCorrelation ToBeUpdatedCounter (advanced)	Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled.	50	int
waitForProvisionCorrelation ToBeUpdatedThreadSleeping Time (advanced)	Interval in millis to sleep each time while waiting for provisional correlation id to be updated.	100	long
errorHandlerLoggingLevel (logging)	Allows to configure the default errorHandler logging level for logging uncaught exceptions.	WARN	LoggingLevel
errorHandlerLogStackTrace (logging)	Allows to control whether stacktraces should be logged or not, by the default errorHandler.	true	boolean
password (security)	Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.		String
username (security)	Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.		String
transacted (transaction)	Specifies whether to use transacted mode	false	boolean
lazyCreateTransaction Manager (transaction)	If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true.	true	boolean
transactionManager (transaction)	The Spring transaction manager to use.		PlatformTransaction Manager
transactionName (transaction)	The name of the transaction to use.		String
transactionTimeout (transaction)	The timeout value of the transaction (in seconds), if using transacted mode.	-1	int

5.3. Usage
复制链接

As AMQP component is inherited from JMS component, the usage of the former is almost identical to the latter:

Using AMQP component

// Consuming from AMQP queue
from("amqp:queue:incoming").
  to(...);
 
// Sending message to the AMQP topic
from(...).
  to("amqp:topic:notify");

// Consuming from AMQP queue
from("amqp:queue:incoming").
  to(...);
 
// Sending message to the AMQP topic
from(...).
  to("amqp:topic:notify");

5.4. Configuring AMQP component
复制链接

Starting from the Camel 2.16.1 you can also use the AMQPComponent#amqp10Component(String connectionURI) factory method to return the AMQP 1.0 component with the pre-configured topic prefix:

Creating AMQP 1.0 component

 AMQPComponent amqp = AMQPComponent.amqp10Component("amqp://guest:guest@localhost:5672");

 AMQPComponent amqp = AMQPComponent.amqp10Component("amqp://guest:guest@localhost:5672");

Copy to Clipboard

Toggle word wrap

Keep in mind that starting from the Camel 2.17 the AMQPComponent#amqp10Component(String connectionURI) factory method has been deprecated on the behalf of the AMQPComponent#amqpComponent(String connectionURI):

Creating AMQP 1.0 component

AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672");
 
AMQPComponent authorizedAmqp = AMQPComponent.amqpComponent("amqp://localhost:5672", "user", "password");

AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672");
 
AMQPComponent authorizedAmqp = AMQPComponent.amqpComponent("amqp://localhost:5672", "user", "password");

Copy to Clipboard

Toggle word wrap

Starting from Camel 2.17, in order to automatically configure the AMQP component, you can also add an instance of org.apache.camel.component.amqp.AMQPConnectionDetails to the registry. For example for Spring Boot you just have to define bean:

AMQP connection details auto-configuration

@Bean
AMQPConnectionDetails amqpConnection() {
  return new AMQPConnectionDetails("amqp://localhost:5672");
}
 
@Bean
AMQPConnectionDetails securedAmqpConnection() {
  return new AMQPConnectionDetails("amqp://lcoalhost:5672", "username", "password");
}

@Bean
AMQPConnectionDetails amqpConnection() {
  return new AMQPConnectionDetails("amqp://localhost:5672");
}
 
@Bean
AMQPConnectionDetails securedAmqpConnection() {
  return new AMQPConnectionDetails("amqp://lcoalhost:5672", "username", "password");
}

Likewise, you can also use CDI producer methods when using Camel-CDI

AMQP connection details auto-configuration for CDI

@Produces
AMQPConnectionDetails amqpConnection() {
  return new AMQPConnectionDetails("amqp://localhost:5672");
}

@Produces
AMQPConnectionDetails amqpConnection() {
  return new AMQPConnectionDetails("amqp://localhost:5672");
}

You can also rely on the Camel properties to read the AMQP connection details. Factory method AMQPConnectionDetails.discoverAMQP() attempts to read Camel properties in a Kubernetes-like convention, just as demonstrated on the snippet below:

AMQP connection details auto-configuration

export AMQP_SERVICE_HOST = "mybroker.com"
export AMQP_SERVICE_PORT = "6666"
export AMQP_SERVICE_USERNAME = "username"
export AMQP_SERVICE_PASSWORD = "password"
 
...
 
@Bean
AMQPConnectionDetails amqpConnection() {
  return AMQPConnectionDetails.discoverAMQP();
}

export AMQP_SERVICE_HOST = "mybroker.com"
export AMQP_SERVICE_PORT = "6666"
export AMQP_SERVICE_USERNAME = "username"
export AMQP_SERVICE_PASSWORD = "password"
 
...
 
@Bean
AMQPConnectionDetails amqpConnection() {
  return AMQPConnectionDetails.discoverAMQP();
}

Enabling AMQP specific options

If you, for example, need to enable amqp.traceFrames you can do that by appending the option to your URI, like the following example:

AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672?amqp.traceFrames=true");

AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672?amqp.traceFrames=true");

5.5. Using topics
复制链接

To have using topics working with camel-amqp you need to configure the component to use topic:// as topic prefix, as shown below:

Keep in mind that both AMQPComponent#amqpComponent() methods and AMQPConnectionDetails pre-configure the component with the topic prefix, so you don’t have to configure it explicitly.

Getting Started

Chapter 6. APNS Component
复制链接

Available as of Camel version 2.8

The apns component is used for sending notifications to iOS devices. The apns components use javapns library.
The component supports sending notifications to Apple Push Notification Servers (APNS) and consuming feedback from the servers.

The consumer is configured with 3600 seconds for polling by default because it is a best practice to consume feedback stream from Apple Push Notification Servers only from time to time. For example: every 1 hour to avoid flooding the servers.

The feedback stream gives informations about inactive devices. You only need to get this informations every some hours if your mobile application is not a heavily used one.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-apns</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

复制链接

Expand

Name	Description	Default	Type
tokens (common)	Configure this property in case you want to statically declare tokens related to devices you want to notify. Tokens are separated by comma.		String
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
sendEmptyMessageWhenIdle (consumer)	If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.	false	boolean
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange.		ExchangePattern
pollStrategy (consumer)	A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.		PollingConsumerPoll Strategy
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean
backoffErrorThreshold (scheduler)	The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.		int
backoffIdleThreshold (scheduler)	The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.		int
backoffMultiplier (scheduler)	To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.		int
delay (scheduler)	Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).	500	long
greedy (scheduler)	If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.	false	boolean
initialDelay (scheduler)	Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).	1000	long
runLoggingLevel (scheduler)	The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.	TRACE	LoggingLevel
scheduledExecutorService (scheduler)	Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.		ScheduledExecutor Service
scheduler (scheduler)	To use a cron scheduler from either camel-spring or camel-quartz2 component	none	ScheduledPollConsumer Scheduler
schedulerProperties (scheduler)	To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.		Map

timeUnit (scheduler)	Time unit for initialDelay and delay options.	MILLISECONDS	TimeUnit
useFixedDelay (scheduler)	Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.	true	boolean

You can append query options to the URI in the following format, ?option=value&option=value&…

6.2.3. Component
复制链接

The ApnsComponent must be configured with a com.notnoop.apns.ApnsService. The service can be created and configured using the org.apache.camel.component.apns.factory.ApnsServiceFactory. See further below for an example. And as well in the test source code.

6.2.3.1. SSL Setting
复制链接

In order to use secure connection, an instance of org.apache.camel.util.jsse.SSLContextParameters should be injected to org.apache.camel.component.apns.factory.ApnsServiceFactory which is used to configure the component. See the test resources for an example. ssl example

6.3. Exchange data format
复制链接

When Camel will fetch feedback data corresponding to inactive devices, it will retrieve a List of InactiveDevice objects. Each InactiveDevice object of the retrieved list will be setted as the In body, and then processed by the consumer endpoint.

6.4. Message Headers
复制链接

Camel Apns uses these headers.

Expand

Property	Default	Description
`CamelApnsTokens`		Empty by default.
`CamelApnsMessageType`	`STRING, PAYLOAD, APNS_NOTIFICATION`	In case you choose PAYLOAD for the message type, then the message will be considered as a APNS payload and sent as is. In case you choose STRING, message will be converted as a APNS payload. From Camel 2.16 onwards APNS_NOTIFICATION is used for sending message body as com.notnoop.apns.ApnsNotification types.

6.5. ApnsServiceFactory builder callback
复制链接

ApnsServiceFactory comes with the empty callback method that could be used to configure (or even replace) the default ApnsServiceBuilder instance. The signature of the method could look as follows:

protected ApnsServiceBuilder configureServiceBuilder(ApnsServiceBuilder serviceBuilder);

protected ApnsServiceBuilder configureServiceBuilder(ApnsServiceBuilder serviceBuilder);

Chapter 7. ASN.1 File DataFormat
复制链接

Available as of Camel version 2.20

The ASN.1 Data Format Data Format [Intoduction to ASN.1](https://www.itu.int/en/ITU-T/asn1/Pages/introduction.aspx) is a Camel Frameworks’s data format implementation based on Bouncy Castle’s bcprov-jdk15on library and jASN.1’s java compiler for the formal notation used for describing data transmitted by telecommunications protocols, regardless of language implementation and physical representation of these data, whatever the application, whether complex or very simple. Messages can be unmarshalled (conversion to simple Java POJO(s)) to plain Java objects. By the help of Camel’s routing engine and data transformations you can then play with POJO(s) and apply customised formatting and call other Camel Component’s to convert and send messages to upstream systems.

7.1. ASN.1 Data Format Options
复制链接

The ASN.1 File dataformat supports 3 options which are listed below.

Expand

Name	Default	Java Type	Description
usingIterator	`false`	`Boolean`	If the asn1 file has more then one entry, the setting this option to true, allows to work with the splitter EIP, to split the data using an iterator in a streaming mode.
clazzName		`String`	Name of class to use when unmarshalling
contentTypeHeader	`false`	`Boolean`	Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

7.2. Unmarshal
复制链接

There are 3 different ways to unmarshal ASN.1 structured messages. (Usually binary files)

In this first example we unmarshal BER file payload to OutputStream and send it to mock endpoint.

from("direct:unmarshal").unmarshal(asn1).to("mock:unmarshal");

from("direct:unmarshal").unmarshal(asn1).to("mock:unmarshal");

Copy to Clipboard

Toggle word wrap

In the second example we unmarshal BER file payload to byte array using Split EIP. The reason for applying Split EIP is that usually each BER file or (ASN.1 structured file) contains multiple records to process and Split EIP helps us to get each record in a file as byte arrays which is actually ASN1Primitive’s instance (by the use of Bouncy Castle’s ASN.1 support in bcprov-jdk15on library) Byte arrays then may be converted to ASN1Primitive by the help of public static method in (ASN1Primitive.fromByteArray) In such example, note that you need to set usingIterator=true

from("direct:unmarshal").unmarshal(asn1).split(body(Iterator.class)).streaming().to("mock:unmarshal");

from("direct:unmarshal").unmarshal(asn1).split(body(Iterator.class)).streaming().to("mock:unmarshal");

Copy to Clipboard

Toggle word wrap

In the last example we unmarshal BER file payload to plain old Java Objects using Split EIP. The reason for applying Split EIP is already mentioned in the previous example. Please note and keep in mind that reason. In such example we also need to set the fully qualified name of the class or <YourObject>.class reference through data format. The important thing to note here is that your object should have been generated by jasn1 compiler which is a nice tool to generate java object representations of your ASN.1 structure. For the reference usage of jasn1 compiler see [JASN.1 Project Page](https://www.openmuc.org/asn1/) and please also see how the compiler is invoked with the help of maven’s exec plugin. For example, in this data format’s unit tests an example ASN.1 structure(TestSMSBerCdr.asn1) is added in src/test/resources/asn1_structure. jasn1 compiler is invoked and java object’s representations are generated in ${basedir}/target/generated/src/test/java The nice thing about this example, you will get POJO instance at the mock endpoint or at whatever your endpoint is.

from("direct:unmarshaldsl")
         .unmarshal()
         .asn1("org.apache.camel.dataformat.asn1.model.testsmscbercdr.SmsCdr")
         .split(body(Iterator.class)).streaming()
.to("mock:unmarshaldsl");

from("direct:unmarshaldsl")
         .unmarshal()
         .asn1("org.apache.camel.dataformat.asn1.model.testsmscbercdr.SmsCdr")
         .split(body(Iterator.class)).streaming()
.to("mock:unmarshaldsl");

7.3. Dependencies
复制链接

To use ASN.1 data format in your camel routes you need to add a dependency on camel-asn1 which implements this data format.

If you use Maven you can just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-asn1</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->

Endpoint options that are not mandatory are denoted by []. When there are no mandatory options for an endpoint, one of the set of [] options MUST be provided. Producer endpoints can also use a special option inBody that in turn should contain the name of the endpoint option whose value will be contained in the Camel Exchange In message.

Any of the endpoint options can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelAS2.<option>. Note that the inBody option overrides message header, i.e. the endpoint option inBody=option would override a CamelAS2.option header.

If a value is not provided for the option defaultRequest either in the endpoint URI or in a message header, it will be assumed to be null. Note that the null value will only be used if other options do not satisfy matching endpoints.

In case of AS2 API errors the endpoint will throw a RuntimeCamelException with a org.apache.http.HttpException derived exception cause.

Chapter 11. Atmosphere Websocket Component
复制链接

Available as of Camel version 2.14

The atmosphere-websocket: component provides Websocket based endpoints for a servlet communicating with external clients over Websocket (as a servlet accepting websocket connections from external clients).
The component uses the SERVLET component and uses the Atmosphere library to support the Websocket transport in various Servlet containers (e..g., Jetty, Tomcat, …).

Unlike the Websocket component that starts the embedded Jetty server, this component uses the servlet provider of the container.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-atmosphere-websocket</artifactId>
    <version>x.x.x</version>

httpRegistry (common)	To use a custom org.apache.camel.component.servlet.HttpRegistry.		HttpRegistry
attachmentMultipart Binding (common)	Whether to automatic bind multipart/form-data as attachments on the Camel Exchange. The options attachmentMultipartBinding=true and disableStreamCache=false cannot work together. Remove disableStreamCache to use AttachmentMultipartBinding. This is turn off by default as this may require servlet specific configuration to enable this when using Servlet’s.	false	boolean
httpBinding (advanced)	To use a custom HttpBinding to control the mapping between Camel message and HttpClient.		HttpBinding
httpConfiguration (advanced)	To use the shared HttpConfiguration as base configuration.		HttpConfiguration
allowJavaSerialized Object (advanced)	Whether to allow java serialization when a request uses context-type=application/x-java-serialized-object. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.	false	boolean
headerFilterStrategy (filter)	To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message.		HeaderFilterStrategy
resolveProperty Placeholders (advanced)	Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders.	true	boolean

复制链接

Expand

Name	Description	Default	Type
chunked (common)	If this option is false the Servlet will disable the HTTP streaming and set the content-length header on the response	true	boolean
disableStreamCache (common)	Determines whether or not the raw input stream from Servlet is cached or not (Camel will read the stream into a in memory/overflow to file, Stream caching) cache. By default Camel will cache the Servlet input stream to support reading it multiple times to ensure it Camel can retrieve all data from the stream. However you can set this option to true when you for example need to access the raw stream, such as streaming it directly to a file or other persistent store. DefaultHttpBinding will copy the request input stream into a stream cache and put it into message body if this option is false to support reading the stream multiple times. If you use Servlet to bridge/proxy an endpoint then consider enabling this option to improve performance, in case you do not need to read the message payload multiple times. The http/http4 producer will by default cache the response body stream. If setting this option to true, then the producers will not cache the response body stream but use the response stream as-is as the message body.	false	boolean
headerFilterStrategy (common)	To use a custom HeaderFilterStrategy to filter header to and from Camel message.		HeaderFilterStrategy
sendToAll (common)	Whether to send to all (broadcast) or send to a single receiver.	false	boolean
transferException (common)	If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a application/x-java-serialized-object content type. On the producer side the exception will be deserialized and thrown as is, instead of the HttpOperationFailedException. The caused exception is required to be serialized. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.	false	boolean
useStreaming (common)	To enable streaming to send data as multiple text fragments.	false	boolean
httpBinding (common)	To use a custom HttpBinding to control the mapping between Camel message and HttpClient.		HttpBinding
async (consumer)	Configure the consumer to work in async mode	false	boolean
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
httpMethodRestrict (consumer)	Used to only allow consuming if the HttpMethod matches, such as GET/POST/PUT etc. Multiple methods can be specified separated by comma.		String
matchOnUriPrefix (consumer)	Whether or not the consumer should try to find a target consumer by matching the URI prefix if no exact match is found.	false	boolean
responseBufferSize (consumer)	To use a custom buffer size on the javax.servlet.ServletResponse.		Integer
servletName (consumer)	Name of the servlet to use	CamelServlet	String
attachmentMultipartBinding (consumer)	Whether to automatic bind multipart/form-data as attachments on the Camel Exchange. The options attachmentMultipartBinding=true and disableStreamCache=false cannot work together. Remove disableStreamCache to use AttachmentMultipartBinding. This is turn off by default as this may require servlet specific configuration to enable this when using Servlet’s.	false	boolean
eagerCheckContentAvailable (consumer)	Whether to eager check whether the HTTP requests has content if the content-length header is 0 or not present. This can be turned on in case HTTP clients do not send streamed data.	false	boolean
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange.		ExchangePattern
optionsEnabled (consumer)	Specifies whether to enable HTTP OPTIONS for this Servlet consumer. By default OPTIONS is turned off.	false	boolean
traceEnabled (consumer)	Specifies whether to enable HTTP TRACE for this Servlet consumer. By default TRACE is turned off.	false	boolean
bridgeEndpoint (producer)	If the option is true, HttpProducer will ignore the Exchange.HTTP_URI header, and use the endpoint’s URI for request. You may also set the option throwExceptionOnFailure to be false to let the HttpProducer send all the fault response back.	false	boolean
connectionClose (producer)	Specifies whether a Connection Close header must be added to HTTP Request. By default connectionClose is false.	false	boolean
copyHeaders (producer)	If this option is true then IN exchange headers will be copied to OUT exchange headers according to copy strategy. Setting this to false, allows to only include the headers from the HTTP response (not propagating IN headers).	true	boolean

Name	Description	Default	Type
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
feedHeader (consumer)	Sets whether to add the feed object as a header	true	boolean
filter (consumer)	Sets whether to use filtering or not of the entries.	true	boolean
lastUpdate (consumer)	Sets the timestamp to be used for filtering entries from the atom feeds. This options is only in conjunction with the splitEntries.		Date
password (consumer)	Sets the password to be used for basic authentication when polling from a HTTP feed		String
sendEmptyMessageWhenIdle (consumer)	If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.	false	boolean
sortEntries (consumer)	Sets whether to sort entries by published date. Only works when splitEntries = true.	false	boolean
splitEntries (consumer)	Sets whether or not entries should be sent individually or whether the entire feed should be sent as a single message	true	boolean
throttleEntries (consumer)	Sets whether all entries identified in a single feed poll should be delivered immediately. If true, only one entry is processed per consumer.delay. Only applicable when splitEntries = true.	true	boolean
username (consumer)	Sets the username to be used for basic authentication when polling from a HTTP feed		String
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange.		ExchangePattern
pollStrategy (consumer)	A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.		PollingConsumerPoll Strategy
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean
backoffErrorThreshold (scheduler)	The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.		int
backoffIdleThreshold (scheduler)	The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.		int
backoffMultiplier (scheduler)	To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.		int
delay (scheduler)	Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).	500	long
greedy (scheduler)	If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.	false	boolean
initialDelay (scheduler)	Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).	1000	long
runLoggingLevel (scheduler)	The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.	TRACE	LoggingLevel
scheduledExecutorService (scheduler)	Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.		ScheduledExecutor Service
scheduler (scheduler)	To use a cron scheduler from either camel-spring or camel-quartz2 component	none	ScheduledPollConsumer Scheduler
schedulerProperties (scheduler)	To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.		Map
startScheduler (scheduler)	Whether the scheduler should be auto started.	true	boolean
timeUnit (scheduler)	Time unit for initialDelay and delay options.	MILLISECONDS	TimeUnit
useFixedDelay (scheduler)	Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.	true	boolean

You can append query options to the URI in the following format, ?option=value&option=value&…

12.3. Exchange data format
复制链接

Camel will set the In body on the returned Exchange with the entries. Depending on the splitEntries flag Camel will either return one Entry or a List<Entry>.

Expand

Option	Value	Behavior
`splitEntries`	`true`	Only a single entry from the currently being processed feed is set: `exchange.in.body(Entry)`
`splitEntries`	`false`	The entire list of entries from the feed is set: `exchange.in.body(List<Entry>)`

Camel can set the Feed object on the In header (see feedHeader option to disable this):

12.4. Message Headers

Available as of Camel version 2.10

This component provides a dataformat for avro, which allows serialization and deserialization of messages using Apache Avro’s binary dataformat. Moreover, it provides support for Apache Avro’s rpc, by providing producers and consumers endpoint for using avro over netty or http.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-avro</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->

19.1. Apache Avro Overview
复制链接

Avro allows you to define message types and a protocol using a json like format and then generate java code for the specified types and messages. An example of how a schema looks like is below.

{"namespace": "org.apache.camel.avro.generated",
 "protocol": "KeyValueProtocol",

 "types": [
     {"name": "Key", "type": "record",
      "fields": [
          {"name": "key",   "type": "string"}
      ]
     },
     {"name": "Value", "type": "record",
      "fields": [
          {"name": "value",   "type": "string"}
      ]
     }
 ],

 "messages": {
     "put": {
         "request": [{"name": "key", "type": "Key"}, {"name": "value", "type": "Value"} ],
         "response": "null"
     },
     "get": {
         "request": [{"name": "key", "type": "Key"}],
         "response": "Value"
     }
 }
}

You can easily generate classes from a schema, using maven, ant etc. More details can be found at the Apache Avro documentation.

However, it doesn’t enforce a schema first approach and you can create schema for your existing classes. Since 2.12 you can use existing protocol interfaces to make RCP calls. You should use interface for the protocol itself and POJO beans or primitive/String classes for parameter and result types. Here is an example of the class that corresponds to schema above:

package org.apache.camel.avro.reflection;

public interface KeyValueProtocol {
    void put(String key, Value value);
    Value get(String key);
}

class Value {
    private String value;
    public String getValue() { return value; }
    public void setValue(String value) { this.value = value; }
}

package org.apache.camel.avro.reflection;

public interface KeyValueProtocol {
    void put(String key, Value value);
    Value get(String key);
}

class Value {
    private String value;
    public String getValue() { return value; }
    public void setValue(String value) { this.value = value; }
}

Note: Existing classes can be used only for RPC (see below), not in data format.

19.2. Using the Avro data format
复制链接

Using the avro data format is as easy as specifying that the class that you want to marshal or unmarshal in your route.

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="direct:in"/>
            <marshal>
                <avro instanceClass="org.apache.camel.dataformat.avro.Message"/>
            </marshal>
            <to uri="log:out"/>
        </route>
    </camelContext>

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="direct:in"/>
            <marshal>
                <avro instanceClass="org.apache.camel.dataformat.avro.Message"/>
            </marshal>
            <to uri="log:out"/>
        </route>
    </camelContext>

An alternative can be to specify the dataformat inside the context and reference it from your route.

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
         <dataFormats>
            <avro id="avro" instanceClass="org.apache.camel.dataformat.avro.Message"/>
        </dataFormats>
        <route>
            <from uri="direct:in"/>
            <marshal ref="avro"/>
            <to uri="log:out"/>
        </route>
    </camelContext>

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
         <dataFormats>
            <avro id="avro" instanceClass="org.apache.camel.dataformat.avro.Message"/>
        </dataFormats>
        <route>
            <from uri="direct:in"/>
            <marshal ref="avro"/>
            <to uri="log:out"/>
        </route>
    </camelContext>

In the same manner you can umarshal using the avro data format.

19.3. Using Avro RPC in Camel
复制链接

As mentioned above Avro also provides RPC support over multiple transports such as http and netty. Camel provides consumers and producers for these two transports.

avro:[transport]:[host]:[port][?options]

avro:[transport]:[host]:[port][?options]

Copy to Clipboard

Toggle word wrap

The supported transport values are currently http or netty.

Since 2.12 you can specify message name right in the URI:

avro:[transport]:[host]:[port][/messageName][?options]

avro:[transport]:[host]:[port][/messageName][?options]

Copy to Clipboard

Toggle word wrap

For consumers this allows you to have multiple routes attached to the same socket. Dispatching to correct route will be done by the avro component automatically. Route with no messageName specified (if any) will be used as default.

When using camel producers for avro ipc, the "in" message body needs to contain the parameters of the operation specified in the avro protocol. The response will be added in the body of the "out" message.

In a similar manner when using camel avro consumers for avro ipc, the requests parameters will be placed inside the "in" message body of the created exchange and once the exchange is processed the body of the "out" message will be send as a response.

Note: By default consumer parameters are wrapped into array. If you’ve got only one parameter, since 2.12 you can use singleParameter URI option to receive it direcly in the "in" message body without array wrapping.

            <process ref="putProcessor"/>

        <route>
            <from uri="avro:netty:localhost:{{avroport}}/get?protocolClassName=org.apache.camel.avro.generated.KeyValueProtocol&singleParameter=true"/>
            <process ref="getProcessor"/>
        </route>

        <route>
            <from uri="avro:netty:localhost:{{avroport}}/put?protocolClassName=org.apache.camel.avro.generated.KeyValueProtocol">

        <route>
            <from uri="avro:netty:localhost:{{avroport}}/get?protocolClassName=org.apache.camel.avro.generated.KeyValueProtocol&singleParameter=true"/>
            <process ref="getProcessor"/>
        </route>

Required DynampDBStream component options

You have to provide the amazonDynamoDbStreamsClient in the Registry with proxies and relevant credentials configured.

23.3. Sequence Numbers
复制链接

You can provide a literal string as the sequence number or provide a bean in the registry. An example of using the bean would be to save your current position in the change feed and restore it on Camel startup.

It is an error to provide a sequence number that is greater than the largest sequence number in the describe-streams result, as this will lead to the AWS call returning an HTTP 400.

23.4. Batch Consumer

This component implements the Batch Consumer.

This allows you for instance to know how many messages exists in this batch and for instance let the Aggregator aggregate this number of messages.

23.5. Usage

You will need to create an instance of AmazonDynamoDBStreamsClient and bind it to the registry

ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

Region region = Region.getRegion(Regions.fromName(region));
region.createClient(AmazonDynamoDBStreamsClient.class, null, clientConfiguration);
// the 'null' here is the AWSCredentialsProvider which defaults to an instance of DefaultAWSCredentialsProviderChain

registry.bind("kinesisClient", client);

ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

Region region = Region.getRegion(Regions.fromName(region));

23.6.1. AWS DynamoDB Streams outage of less than 24 hours
复制链接

The consumer will resume from the last seen sequence number (as implemented for CAMEL-9515), so you should receive a flood of events in quick succession, as long as the outage did not also include DynamoDB itself.

23.6.2. AWS DynamoDB Streams outage of more than 24 hours

AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey");

ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

AmazonS3 client = new AmazonS3Client(awsCredentials, clientConfiguration);

registry.bind("client", client);

AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey");

ClientConfiguration clientConfiguration = new ClientConfiguration();

clientConfiguration.setProxyPort(8080);

AmazonS3 client = new AmazonS3Client(awsCredentials, clientConfiguration);

registry.bind("client", client);

31.4.5. Use KMS with the S3 component
复制链接

To use AWS KMS to encrypt/decrypt data by using AWS infrastructure you can use the options introduced in 2.21.x like in the following example

from("file:tmp/test?fileName=test.txt")
     .setHeader(S3Constants.KEY, constant("testFile"))
     .to("aws-s3://mybucket?amazonS3Client=#client&useAwsKMS=true&awsKMSKeyId=3f0637ad-296a-3dfe-a796-e60654fb128c");

from("file:tmp/test?fileName=test.txt")
     .setHeader(S3Constants.KEY, constant("testFile"))
     .to("aws-s3://mybucket?amazonS3Client=#client&useAwsKMS=true&awsKMSKeyId=3f0637ad-296a-3dfe-a796-e60654fb128c");

Copy to Clipboard

Toggle word wrap

In this way you’ll ask to S3, to use the KMS key 3f0637ad-296a-3dfe-a796-e60654fb128c, to encrypt the file test.txt. When you’ll ask to download this file, the decryption will be done directly before the download.

31.4.6. Use "useIAMCredentials" with the s3 component
复制链接

To use AWS IAM credentials, you must first verify that the EC2 in which you are launching the Camel application on has an IAM role associated with it containing the appropriate policies attached to run effectively. Keep in mind that this feature should only be set to "true" on remote instances. To clarify even further, you must still use static credentials locally since IAM is an AWS specific component, but AWS environments should now be easier to manage. After this is implemented and understood, you can set the query parameter "useIAMCredentials" to "true" for AWS environments! To effectively toggle this on and off based on local and remote environments, you can consider enabling this query parameter with system environment variables. For example, your code could set the "useIAMCredentials" query parameter to "true", when the system environment variable called "isRemote" is set to true (there are many other ways to do this and this should act as a simple example). Although it doesn’t take away the need for static credentials completely, using IAM credentials on AWS environments takes away the need to refresh on remote environments and adds a major security boost (IAM credentials are refreshed automatically every 6 hours and update when their policies are updated). This is the AWS recommended way to manage credentials and therefore should be used as often as possible.

31.5. Dependencies

Maven users will need to add the following dependency to their pom.xml.

where ${camel-version} must be replaced by the actual version of Camel (2.6 or higher).

35.6. JMS-style Selectors
复制链接

SQS does not allow selectors, but you can effectively achieve this by using the Camel Filter EIP and setting an appropriate visibilityTimeout. When SQS dispatches a message, it will wait up to the visibility timeout before it will try to dispatch the message to a different consumer unless a DeleteMessage is received. By default, Camel will always send the DeleteMessage at the end of the route, unless the route ended in failure. To achieve appropriate filtering and not send the DeleteMessage even on successful completion of the route, use a Filter:

from("aws-sqs://MyQueue?amazonSQSClient=#client&defaultVisibilityTimeout=5000&deleteIfFiltered=false")
.filter("${header.login} == true")
.to("mock:result");

from("aws-sqs://MyQueue?amazonSQSClient=#client&defaultVisibilityTimeout=5000&deleteIfFiltered=false")
.filter("${header.login} == true")
.to("mock:result");

Copy to Clipboard

Toggle word wrap

In the above code, if an exchange doesn’t have an appropriate header, it will not make it through the filter AND also not be deleted from the SQS queue. After 5000 miliseconds, the message will become visible to other consumers.

If you need more control over the AmazonSimpleWorkflowClient instance configuration you can create your own instance and refer to it from the URI:

The #client refers to a AmazonSimpleWorkflowClient in the Registry.

For example if your Camel Application is running behind a firewall:

AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey");
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

AmazonSimpleWorkflowClient client = new AmazonSimpleWorkflowClient(awsCredentials, clientConfiguration);

registry.bind("client", client);

AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey");
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

AmazonSimpleWorkflowClient client = new AmazonSimpleWorkflowClient(awsCredentials, clientConfiguration);

Available as of Camel 2.21

The camel-aws-xray component is used for tracing and timing incoming and outgoing Camel messages using AWS XRay.

Events (subsegments) are captured for incoming and outgoing messages being sent to/from Camel.

37.1. Dependency
复制链接

In order to include AWS XRay support into Camel, the archive containing the Camel related AWS XRay related classes need to be added to the project. In addition to that, AWS XRay libraries also need to be available.

To include both, AWS XRay and Camel, dependencies use the following Maven imports:

37.2. Configuration
复制链接

The configuration properties for the AWS XRay tracer are:

Expand

Option	Default	Description
addExcludePatterns		Sets exclude pattern(s) that will disable tracing for Camel messages that matches the pattern. The content is a Set<String> where the key is a pattern matching routeId’s. The pattern uses the rules from Intercept.
setTracingStrategy	NoopTracingStrategy	Allows a custom Camel `InterceptStrategy` to be provided in order to track invoked processor definitions like `BeanDefinition` or `ProcessDefinition`. `TraceAnnotatedTracingStrategy` will track any classes invoked via `.bean(…)` or `.process(…)` that contain a `@XRayTrace` annotation at class level.

There is currently only one way an AWS XRay tracer can be configured to provide distributed tracing for a Camel application:

37.2.1. Explicit
复制链接

Include the camel-aws-xray component in your POM, along with any specific dependencies associated with the AWS XRay Tracer.

To explicitly configure AWS XRay support, instantiate the XRayTracer and initialize the camel context. You can optionally specify a Tracer, or alternatively it can be implicitly discovered using the Registry or ServiceLoader.

XRayTracer xrayTracer = new XRayTracer();
// By default it uses a NoopTracingStrategy, but you can override it with a specific InterceptStrategy implementation.
xrayTracer.setTracingStrategy(...);
// And then initialize the context
xrayTracer.init(camelContext);

XRayTracer xrayTracer = new XRayTracer();
// By default it uses a NoopTracingStrategy, but you can override it with a specific InterceptStrategy implementation.
xrayTracer.setTracingStrategy(...);
// And then initialize the context
xrayTracer.init(camelContext);

Copy to Clipboard

Toggle word wrap

To use XRayTracer in XML, all you need to do is to define the AWS XRay tracer bean. Camel will automatically discover and use it.

  <bean id="tracingStrategy" class="..."/>
  <bean id="aws-xray-tracer" class="org.apache.camel.component.aws.xray.XRayTracer" />
    <property name="tracer" ref="tracingStrategy"/>
  </bean>

  <bean id="tracingStrategy" class="..."/>
  <bean id="aws-xray-tracer" class="org.apache.camel.component.aws.xray.XRayTracer" />
    <property name="tracer" ref="tracingStrategy"/>
  </bean>

Copy to Clipboard

Toggle word wrap

In case of the default NoopTracingStrategy only the creation and deletion of exchanges is tracked but not the invocation of certain beans or EIP patterns.

37.2.2. Tracking of comprehensive route execution
复制链接

In order to track the execution of an exchange among multiple routes, on exchange creation a unique trace ID is generated and stored in the headers if no corresponding value was yet available. This trace ID is copied over to new exchanges in order to keep a consistent view of the processed exchange.

As AWS XRay traces work on a thread-local basis the current sub/segment should be copied over to the new thread and set as explained in in the AWS XRay documentation. The Camel AWS XRay component therefore provides an additional header field that the component will use in order to set the passed AWS XRay Entity to the new thread and thus keep the tracked data to the route rather than exposing a new segment which seems uncorrelated with any of the executed routes.

The component will use the following constants found in the headers of the exchange:

Expand

Header	Description
Camel-AWS-XRay-Trace-ID	Contains a reference to the AWS XRay `TraceID` object to provide a comprehensive view of the invoked routes
Camel-AWS-XRay-Trace-Entity	Contains a reference to the actual AWS XRay `Segment` or `Subsegment` which is copied over to the new thread. This header should be set in case a new thread is spawned and the performed tasks should be exposed as part of the executed route instead of creating a new unrelated segment.

Note that the AWS XRay Entity (i.e., Segment and Subsegment) are not serializable and therefore should not get passed to other JVM processes.

37.3. Example

You can find an example demonstrating the way to configure AWS XRay tracing within the tests accompanying this project.

复制链接

Available as of Camel version 2.14

The barcode data format is based on the zxing library. The goal of this component is to create a barcode image from a String (marshal) and a String from a barcode image (unmarshal). You’re free to use all features that zxing offers.

41.1. Dependencies
复制链接

To use the barcode data format in your camel routes you need to add the a dependency on camel-barcode which implements this data format.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>

41.2. Barcode Options
复制链接

The Barcode dataformat supports 5 options which are listed below.

Expand

Name	Default	Java Type	Description
width		`Integer`	Width of the barcode
height		`Integer`	Height of the barcode
imageType		`String`	Image type of the barcode such as png
barcodeFormat		`String`	Barcode format such as QR-Code
contentTypeHeader	`false`	`Boolean`	Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

41.3. Using the Java DSL
复制链接

First you have to initialize the barcode data fomat class. You can use the default constructor, or one of parameterized (see JavaDoc). The default values are:

Expand

Parameter	Default Value
image type (BarcodeImageType)	PNG
width	100 px
height	100 px
encoding	UTF-8
barcode format (BarcodeFormat)	QR-Code

// QR-Code default
DataFormat code = new BarcodeDataFormat();

// QR-Code default
DataFormat code = new BarcodeDataFormat();

Chapter 42. Base64 DataFormat
复制链接

Available as of Camel version 2.11

The Base64 data format is used for base64 encoding and decoding.

42.1. Options
复制链接

The Base64 dataformat supports 4 options which are listed below.

Expand

Name	Default	Java Type	Description
lineLength	`76`	`Integer`	To specific a maximum line length for the encoded data. By default 76 is used.
lineSeparator		`String`	The line separators to use. Uses new line characters (CRLF) by default.
urlSafe	`false`	`Boolean`	Instead of emitting '' and '/' we emit '-' and '_' respectively. urlSafe is only applied to encode operations. Decoding seamlessly handles both modes. Is by default false.
contentTypeHeader	`false`	`Boolean`	Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

In Spring DSL, you configure the data format using this tag:

<camelContext>
    <dataFormats>
        <!-- for a newline character (\n), use the HTML entity notation coupled with the ASCII code. -->
        <base64 lineSeparator="&#10;" id="base64withNewLine" />
        <base64 lineLength="64" id="base64withLineLength64" />
    </dataFormats>
    ...
</camelContext>

<camelContext>
    <dataFormats>
        <!-- for a newline character (\n), use the HTML entity notation coupled with the ASCII code. -->
        <base64 lineSeparator="&#10;" id="base64withNewLine" />
        <base64 lineLength="64" id="base64withLineLength64" />
    </dataFormats>
    ...
</camelContext>

In this example we unmarshal the payload from the JMS queue to a byte[] object, before its processed by the newOrder processor.

from("jms://queue/order")
    .unmarshal().base64()
    .process("newOrder");

from("jms://queue/order")
    .unmarshal().base64()
    .process("newOrder");

42.4. Dependencies
复制链接

To use Base64 in your Camel routes you need to add a dependency on camel-base64 which implements this data format.

If you use Maven you can just add the following to your pom.xml:

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-base64</artifactId>
  <version>x.x.x</version>  <!-- use the same version as your Camel core version -->
</dependency>

Deprecation note: This option is used internally by Camel, and is not intended for end users to use.	false	boolean

synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean

You can append query options to the URI in the following format, ?option=value&option=value&…

43.3. Using
复制链接

The object instance that is used to consume messages must be explicitly registered with the Registry. For example, if you are using Spring you must define the bean in the Spring configuration, spring.xml; or if you don’t use Spring, by registering the bean in JNDI.

Error formatting macro: snippet: java.lang.IndexOutOfBoundsException: Index: 20, Size: 20

Once an endpoint has been registered, you can build Camel routes that use it to process exchanges.

A bean: endpoint cannot be defined as the input to the route; i.e. you cannot consume from it, you can only route from some inbound message Endpoint to the bean endpoint as output. So consider using a direct: or queue: endpoint as the input.

You can use the createProxy() methods on ProxyHelper to create a proxy that will generate BeanExchanges and send them to any endpoint:

And the same route using Spring DSL:

<route>
   <from uri="direct:hello">
   <to uri="bean:bye"/>
</route>

<route>
   <from uri="direct:hello">
   <to uri="bean:bye"/>
</route>

Copy to Clipboard

Toggle word wrap

43.4. Bean as endpoint
复制链接

Camel also supports invoking Bean as an Endpoint. In the route below:

What happens is that when the exchange is routed to the myBean Camel will use the Bean Binding to invoke the bean.
The source for the bean is just a plain POJO:

Camel will use Bean Binding to invoke the sayHello method, by converting the Exchange’s In body to the String type and storing the output of the method on the Exchange Out body.

43.5. Java DSL bean syntax
复制链接

Java DSL comes with syntactic sugar for the Bean component. Instead of specifying the bean explicitly as the endpoint (i.e. to("bean:beanName")) you can use the following syntax:

// Send message to the bean endpoint
// and invoke method resolved using Bean Binding.
from("direct:start").beanRef("beanName");

// Send message to the bean endpoint
// and invoke given method.
from("direct:start").beanRef("beanName", "methodName");

// Send message to the bean endpoint
// and invoke method resolved using Bean Binding.
from("direct:start").beanRef("beanName");

// Send message to the bean endpoint
// and invoke given method.
from("direct:start").beanRef("beanName", "methodName");

Copy to Clipboard

Toggle word wrap

Instead of passing name of the reference to the bean (so that Camel will lookup for it in the registry), you can specify the bean itself:

// Send message to the given bean instance.
from("direct:start").bean(new ExampleBean());

// Explicit selection of bean method to be invoked.
from("direct:start").bean(new ExampleBean(), "methodName");

// Camel will create the instance of bean and cache it for you.
from("direct:start").bean(ExampleBean.class);

// Send message to the given bean instance.
from("direct:start").bean(new ExampleBean());

// Explicit selection of bean method to be invoked.
from("direct:start").bean(new ExampleBean(), "methodName");

// Camel will create the instance of bean and cache it for you.
from("direct:start").bean(ExampleBean.class);

43.6. Bean Binding

How bean methods to be invoked are chosen (if they are not specified explicitly through the method parameter) and how parameter values are constructed from the Message are all defined by the Bean Binding mechanism which is used throughout all of the various Bean Integration mechanisms in Camel.

Chapter 44. BeanIO DataFormat
复制链接

Available as of Camel version 2.10

The BeanIO Data Format uses BeanIO to handle flat payloads (such as XML, CSV, delimited, or fixed length formats).

BeanIO is configured using a mappings XML file where you define the mapping from the flat format to Objects (POJOs). This mapping file is mandatory to use.

44.1. Options
复制链接

The BeanIO dataformat supports 9 options which are listed below.

Expand

Name	Default	Java Type	Description
mapping		`String`	The BeanIO mapping file. Is by default loaded from the classpath. You can prefix with file:, http:, or classpath: to denote from where to load the mapping file.
streamName		`String`	The name of the stream to use.
ignoreUnidentifiedRecords	`false`	`Boolean`	Whether to ignore unidentified records.
ignoreUnexpectedRecords	`false`	`Boolean`	Whether to ignore unexpected records.
ignoreInvalidRecords	`false`	`Boolean`	Whether to ignore invalid records.
encoding		`String`	The charset to use. Is by default the JVM platform default charset.
beanReaderErrorHandlerType		`String`	To use a custom org.apache.camel.dataformat.beanio.BeanIOErrorHandler as error handler while parsing. Configure the fully qualified class name of the error handler. Notice the options ignoreUnidentifiedRecords, ignoreUnexpectedRecords, and ignoreInvalidRecords may not be in use when you use a custom error handler.
unmarshalSingleObject	`false`	`Boolean`	This options controls whether to unmarshal as a list of objects or as a single object only. The former is the default mode, and the latter is only intended in special use-cases where beanio maps the Camel message to a single POJO bean.
contentTypeHeader	`false`	`Boolean`	Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

44.2. Usage
复制链接

An example of a mapping file is here.

44.2.1. Using Java DSL
复制链接

To use the BeanIODataFormat you need to configure the data format with the mapping file, as well the name of the stream.
In Java DSL this can be done as shown below. The streamName is "employeeFile".

Then we have two routes. The first route is for transforming CSV data into a List<Employee> Java objects. Which we then split, so the mock endpoint
receives a message for each row.

The 2nd route is for the reverse operation, to transform a List<Employee> into a stream of CSV data.

The CSV data could for example be as below:

44.2.2. Using XML DSL
复制链接

To use the BeanIO data format in XML, you need to configure it using the <beanio> XML tag as shown below. The routes is similar to the example above.

44.3. Dependencies
复制链接

To use BeanIO in your Camel routes you need to add a dependency on camel-beanio which implements this data format.

If you use Maven you can just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-beanio</artifactId>
  <version>2.10.0</version>

Chapter 45. Beanstalk Component
复制链接

Available as of Camel version 2.15

camel-beanstalk project provides a Camel component for job retrieval and post-processing of Beanstalk jobs.

You can find the detailed explanation of Beanstalk job lifecycle at Beanstalk protocol.

45.1. Dependencies
复制链接

Maven users need to add the following dependency to their pom.xml

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-beanstalk</artifactId>
  <version>${camel-version}</version>
</dependency>

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-beanstalk</artifactId>
  <version>${camel-version}</version>
</dependency>

Copy to Clipboard

where ${camel-version} must be replaced by the actual version of Camel (2.15.0 or higher).

45.2. URI format
复制链接

beanstalk://[host[:port]][/tube][?options]

beanstalk://[host[:port]][/tube][?options]

Copy to Clipboard

Toggle word wrap

You may omit either port or both host and port: for the Beanstalk defaults to be used (“localhost” and 11300). If you omit tube, Beanstalk component will use the tube with name “default”.

When listening, you may probably want to watch for jobs from several tubes. Just separate them with plus sign, e.g.

beanstalk://localhost:11300/tube1+tube2

beanstalk://localhost:11300/tube1+tube2

Copy to Clipboard

Toggle word wrap

Tube name will be URL decoded, so if your tube names include special characters like + or ?, you need to URL-encode them appropriately, or use the RAW syntax, see more details here.

By the way, you cannot specify several tubes when you are writing jobs into Beanstalk.

45.3. Beanstalk options
复制链接

The Beanstalk component supports 2 options which are listed below.

Expand

Name	Description	Default	Type
connectionSettings Factory (common)	Custom ConnectionSettingsFactory. Specify which ConnectionSettingsFactory to use to make connections to Beanstalkd. Especially useful for unit testing without beanstalkd daemon (you can mock ConnectionSettings)		ConnectionSettings Factory

bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.	false	boolean
onFailure (consumer)	Command to use when processing failed.		BeanstalkCommand
sendEmptyMessageWhenIdle (consumer)	If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.	false	boolean
useBlockIO (consumer)	Whether to use blockIO.	true	boolean
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the exchange pattern when the consumer creates an exchange.		ExchangePattern
pollStrategy (consumer)	A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.		PollingConsumerPoll Strategy

backoffErrorThreshold (scheduler)	The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.		int
backoffIdleThreshold (scheduler)	The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.		int
backoffMultiplier (scheduler)	To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.		int
delay (scheduler)	Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).	500	long
greedy (scheduler)	If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.	false	boolean
initialDelay (scheduler)	Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).	1000	long
runLoggingLevel (scheduler)	The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.	TRACE	LoggingLevel
scheduledExecutorService (scheduler)	Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.		ScheduledExecutor Service
scheduler (scheduler)	To use a cron scheduler from either camel-spring or camel-quartz2 component	none	ScheduledPollConsumer Scheduler
schedulerProperties (scheduler)	To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.		Map

timeUnit (scheduler)	Time unit for initialDelay and delay options.	MILLISECONDS	TimeUnit
useFixedDelay (scheduler)	Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.	true	boolean

Producer behavior is affected by the command parameter which tells what to do with the job, it can be

The consumer may delete the job immediately after reserving it or wait until Camel routes process it. While the first scenario is more like a “message queue”, the second is similar to “job queue”. This behavior is controlled by consumer.awaitJob parameter, which equals true by default (following Beanstalkd nature).

When synchronous, the consumer calls delete on successful job completion and calls bury on failure. You can choose which command to execute in the case of failure by specifying consumer.onFailure parameter in the URI. It can take values of bury, delete or release.

There is a boolean parameter consumer.useBlockIO which corresponds to the same parameter in JavaBeanstalkClient library. By default it is true.

Be careful when specifying release, as the failed job will immediately become available in the same tube and your consumer will try to acquire it again. You can release and specify jobDelay though.

The beanstalk consumer is a Scheduled Polling Consumer which means there is more options you can configure, such as how frequent the consumer should poll. For more details see Polling Consumer.

45.4. Consumer Headers
复制链接

The consumer stores a number of job headers in the Exchange message:

Expand

Property	Type	Description
beanstalk.jobId	long	Job ID
beanstalk.tube	string	the name of the tube that contains this job
beanstalk.state	string	“ready” or “delayed” or “reserved” or “buried” (must be “reserved”)
beanstalk.priority	long	the priority value set
beanstalk.age	int	the time in seconds since the put command that created this job
beanstalk.time-left	int	the number of seconds left until the server puts this job into the ready queue
beanstalk.timeouts	int	the number of times this job has timed out during a reservation
beanstalk.releases	int	the number of times a client has released this job from a reservation
beanstalk.buries	int	the number of times this job has been buried
beanstalk.kicks	int	the number of times this job has been kicked

45.5. Examples
复制链接

This Camel component lets you both request the jobs for processing and supply them to Beanstalkd daemon. Our simple demo routes may look like

from("beanstalk:testTube").
   log("Processing job #${property.beanstalk.jobId} with body ${in.body}").
   process(new Processor() {
     @Override
     public void process(Exchange exchange) {
       // try to make integer value out of body
       exchange.getIn().setBody( Integer.valueOf(exchange.getIn().getBody(classOf[String])) );
     }
   }).
   log("Parsed job #${property.beanstalk.jobId} to body ${in.body}");

from("beanstalk:testTube").
   log("Processing job #${property.beanstalk.jobId} with body ${in.body}").
   process(new Processor() {
     @Override
     public void process(Exchange exchange) {
       // try to make integer value out of body
       exchange.getIn().setBody( Integer.valueOf(exchange.getIn().getBody(classOf[String])) );
     }
   }).
   log("Parsed job #${property.beanstalk.jobId} to body ${in.body}");

   setBody(constant(10)).log("Kick ${in.body} buried/delayed tasks").
   to("beanstalk:testTube?command=kick");

Copy to Clipboard

Toggle word wrap

In the first route we are listening for new jobs in tube “testTube”. When they are arriving, we are trying to parse integer value from the message body. If done successful, we log it and this successful exchange completion makes Camel component to delete this job from Beanstalk automatically. Contrary, when we cannot parse the job data, the exchange failed and the Camel component buries it by default, so that it can be processed later or probably we are going to inspect failed jobs manually.

So the second route periodically requests Beanstalk to kick 10 jobs out of buried and/or delayed state to the normal queue.

46.3. OSGi deployment
复制链接

To use Hibernate Validator in the OSGi environment use dedicated ValidationProviderResolver implementation, just as org.apache.camel.component.bean.validator.HibernateValidationProviderResolver. The snippet below demonstrates this approach. Keep in mind that you can use HibernateValidationProviderResolver starting from the Camel 2.13.0.

Using HibernateValidationProviderResolver

from("direct:test").
  to("bean-validator://ValidationProviderResolverTest?validationProviderResolver=#myValidationProviderResolver");

...

<bean id="myValidationProviderResolver" class="org.apache.camel.component.bean.validator.HibernateValidationProviderResolver"/>

Assumed we have a java bean with the following annotations

Car.java

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 5, max = 14, groups = OptionalChecks.class)
    private String licensePlate;

    // getter and setter
}

public class Car {

    @NotNull
    private String manufacturer;

    @Size(min = 5, max = 14, groups = OptionalChecks.class)
    private String licensePlate;

    // getter and setter
}

Copy to Clipboard

and an interface definition for our custom validation group

OptionalChecks.java

Copy to Clipboard

Toggle word wrap

with the following Camel route, only the @NotNull constraints on the attributes manufacturer and licensePlate will be validated (Camel uses the default group javax.validation.groups.Default).

.to("bean-validator://x")
.to("mock:end")

from("direct:start")
.to("bean-validator://x")
.to("mock:end")

Copy to Clipboard

Toggle word wrap

If you want to check the constraints from the group OptionalChecks, you have to define the route like this

from("direct:start")
.to("bean-validator://x?group=OptionalChecks")
.to("mock:end")

from("direct:start")
.to("bean-validator://x?group=OptionalChecks")
.to("mock:end")

Copy to Clipboard

Toggle word wrap

If you want to check the constraints from both groups, you have to define a new interface first

@GroupSequence({Default.class, OptionalChecks.class})
public interface AllChecks {
}

@GroupSequence({Default.class, OptionalChecks.class})
public interface AllChecks {
}

Copy to Clipboard

Toggle word wrap

and then your route definition should looks like this

from("direct:start")
.to("bean-validator://x?group=AllChecks")
.to("mock:end")

from("direct:start")
.to("bean-validator://x?group=AllChecks")
.to("mock:end")

Copy to Clipboard

Toggle word wrap

And if you have to provide your own message interpolator, traversable resolver and constraint validator factory, you have to write a route like this

<bean id="myMessageInterpolator" class="my.ConstraintValidatorFactory" />
<bean id="myTraversableResolver" class="my.TraversableResolver" />
<bean id="myConstraintValidatorFactory" class="my.ConstraintValidatorFactory" />

from("direct:start")
.to("bean-validator://x?group=AllChecks&messageInterpolator=#myMessageInterpolator
&traversableResolver=#myTraversableResolver&constraintValidatorFactory=#myConstraintValidatorFactory")
.to("mock:end")

<bean id="myMessageInterpolator" class="my.ConstraintValidatorFactory" />
<bean id="myTraversableResolver" class="my.TraversableResolver" />
<bean id="myConstraintValidatorFactory" class="my.ConstraintValidatorFactory" />

from("direct:start")
.to("bean-validator://x?group=AllChecks&messageInterpolator=#myMessageInterpolator
&traversableResolver=#myTraversableResolver&constraintValidatorFactory=#myConstraintValidatorFactory")
.to("mock:end")

Copy to Clipboard

Toggle word wrap

It’s also possible to describe your constraints as XML and not as Java annotations. In this case, you have to provide the file META-INF/validation.xml which could looks like this

Configuring Camel
Component
Endpoint
Getting Started

Chapter 47. Binding Component (deprecated)
复制链接

Available as of Camel version 2.11

In Camel terms a binding is a way of wrapping an Endpoint in a contract; such as a Data Format, a Content Enricher or validation step. Bindings are completely optional and you can choose to use them on any camel endpoint.

Bindings are inspired by the work of SwitchYard project adding service contracts to various technologies like Camel and many others. But rather than the SwitchYard approach of wrapping Camel in SCA, Camel Bindings provide a way of wrapping Camel endpoints with contracts inside the Camel framework itself; so you can use them easily inside any Camel route.

47.1. Options
复制链接

The Binding component has no options.

The Binding endpoint is configured using URI syntax:

binding:bindingName:delegateUri

binding:bindingName:delegateUri

Copy to Clipboard

Toggle word wrap

with the following path and query parameters:

47.1.1. Path Parameters (2 parameters):
复制链接

Expand

Name	Description	Default	Type
bindingName	Required Name of the binding to lookup in the Camel registry.		String
delegateUri	Required Uri of the delegate endpoint.		String

47.1.2. Query Parameters (4 parameters):
复制链接

Expand

Name	Description	Default	Type
bridgeErrorHandler (consumer)	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN/ERROR level and ignored.	false	boolean
exceptionHandler (consumer)	To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN/ERROR level and ignored.		ExceptionHandler
exchangePattern (consumer)	Sets the default exchange pattern when creating an exchange.		ExchangePattern
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean

47.2. Using Bindings
复制链接

A Binding is currently a bean which defines the contract (though we’ll hopefully add bindings to the Camel DSL).

There are a few approaches to defining a bound endpoint (i.e. an endpoint bound with a Binding).

47.3. Using the binding URI
复制链接

You can prefix any endpoint URI with binding:nameOfBinding: where nameOfBinding is the name of the Binding bean in your registry.

from("binding:jaxb:activemq:myQueue").to("binding:jaxb:activemq:anotherQueue")

from("binding:jaxb:activemq:myQueue").to("binding:jaxb:activemq:anotherQueue")

Copy to Clipboard

Toggle word wrap

Here we are using the "jaxb" binding which may, for example, use the JAXB Data Format to marshal and unmarshal messages.

47.4. Using a BindingComponent
复制链接

There is a Component called BindingComponent which can be configured in your Registry by dependency injection which allows the creation of endpoints which are already bound to some binding.

For example if you registered a new component called "jsonmq" in your registry using code like this

JacksonDataFormat format = new JacksonDataFormat(MyBean.class);
context.bind("jsonmq", new BindingComponent(new DataFormatBinding(format), "activemq:foo."));

JacksonDataFormat format = new JacksonDataFormat(MyBean.class);
context.bind("jsonmq", new BindingComponent(new DataFormatBinding(format), "activemq:foo."));

Copy to Clipboard

Toggle word wrap

Then you could use the endpoint as if it were any other endpoint.

from("jsonmq:myQueue").to("jsonmq:anotherQueue")

from("jsonmq:myQueue").to("jsonmq:anotherQueue")

Copy to Clipboard

Toggle word wrap

which would be using the queueus "foo.myQueue" and "foo.anotherQueue" and would use the given Jackson Data Format to marshal on and off the queue.

47.5. When to use Bindings
复制链接

If you only use an endpoint once in a single route; a binding may actually be more complex and more work than just using the 'raw' endpoint directly and using explicit marshalling and validation in the camel route as normal.

However bindings can help when you are composing many routes together; or using a single route as a 'template' that is configured input and output endpoints; bindings then provide a nice way to wrap up a contract and endpoint together.

Another good use case for bindings is when you are using many endpoints which use the same binding; rather than always having to mention a specific data format or validation rule, you can just use the BindingComponent to wrap the endpoints in the binding of your choice.

So bindings are a composition tool really; only use them when they make sense - the extra complexity may not be worth it unless you have lots of routes or endpoints.

Chapter 48. Bindy DataFormat
复制链接

Available as of Camel version 2.0

The goal of this component is to allow the parsing/binding of non-structured data (or to be more precise non-XML data)
to/from Java Beans that have binding mappings defined with annotations. Using Bindy, you can bind data from sources such as :

CSV records,
Fixed-length records,
FIX messages,
or almost any other non-structured data

to one or many Plain Old Java Object (POJO). Bindy converts the data according to the type of the java property. POJOs can be linked together with one-to-many relationships available in some cases. Moreover, for data type like Date, Double, Float, Integer, Short, Long and BigDecimal, you can provide the pattern to apply during the formatting of the property.

For the BigDecimal numbers, you can also define the precision and the decimal or grouping separators.

Expand

Type	Format Type	Pattern example	Link
Date	DateFormat	`dd-MM-yyyy`	http://java.sun.com/j2se/1.5.0/docs/api/java/text/SimpleDateFormat.html
Decimal*	Decimalformat	`..##`	http://java.sun.com/j2se/1.5.0/docs/api/java/text/DecimalFormat.html

Decimal* = Double, Integer, Float, Short, Long

*Format supported*

Copy to Clipboard

This first release only support comma separated values fields and key value pair fields (e.g. : FIX messages).

To work with camel-bindy, you must first define your model in a package (e.g. com.acme.model) and for each model class (e.g. Order, Client, Instrument, …) add the required annotations (described hereafter) to the Class or field.

*Multiple models*

*Multiple models*

Copy to Clipboard

Toggle word wrap

If you use multiple models, each model has to be placed in it’s own package to prevent unpredictable results.

From Camel 2.16 onwards this is no longer the case, as you can safely have multiple models in the same package, as you configure bindy using class names instead of package names now.

48.1. Options
复制链接

The Bindy dataformat supports 5 options which are listed below.

Expand

Name	Default	Java Type	Description
type		`BindyType`	Whether to use csv, fixed or key value pairs mode. The default value is either Csv or KeyValue depending on chosen dataformat.
classType		`String`	Name of model class to use.
locale		`String`	To configure a default locale to use, such as us for united states. To use the JVM platform default locale then use the name default
unwrapSingleInstance	`true`	`Boolean`	When unmarshalling should a single instance be unwrapped and returned instead of wrapped in a java.util.List.
contentTypeHeader	`false`	`Boolean`	Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

48.2. Annotations
复制链接

The annotations created allow to map different concept of your model to the POJO like :

Type of record (csv, key value pair (e.g. FIX message), fixed length …),
Link (to link object in another object),
DataField and their properties (int, type, …),
KeyValuePairField (for key = value format like we have in FIX financial messages),
Section (to identify header, body and footer section),
OneToMany,
BindyConverter (since 2.18.0),
FormatFactories (since 2.18.0)

This section will describe them :

48.3. 1. CsvRecord
复制链接

The CsvRecord annotation is used to identified the root class of the model. It represents a record = a line of a CSV file and can be linked to several children model classes.

Expand

Annotation name	Record type	Level
CsvRecord	csv	Class

Expand

Parameter name	type	Info
separator	string	mandatory - can be ',' or ';' or 'anything'. This value is interpreted as a regular expression. If you want to use a sign which has a special meaning in regular expressions, e.g. the '\|' sign, than you have to mask it, like '\|'
skipFirstLine	boolean	optional - default value = false - allow to skip the first line of the CSV file
crlf	string	optional - possible values = WINDOWS,UNIX,MAC, or custom; default value. WINDOWS - allow to define the carriage return character to use. If you specify a value other than the three listed before, the value you enter (custom) will be used as the CRLF character(s)
generateHeaderColumns	boolean	optional - default value = false - uses to generate the header columns of the CSV generates
autospanLine	boolean	Camel 2.13/2.12.2: optional - default value = false - if enabled then the last column is auto spanned to end of line, for example if its a comment, etc this allows the line to contain all characters, also the delimiter char.
isOrdered	boolean	optional - default value = false - allow to change the order of the fields when CSV is generated
quote	String	Camel 2.8.3/2.9: option - allow to specify a quote character of the fields when CSV is generated. This annotation is associated to the root class of the model and must be declared one time.
quoting	boolean	Camel 2.11:optional - default value = false - Indicate if the values (and headers) must be quoted when marshaling when CSV is generated.
endWithLineBreak	boolean	Camel 2.21: optional - default value = true - Indicate if the CSV generated file should end with a line break.

case 1 : separator = ','

The separator used to segregate the fields in the CSV record is ',' :

10, J, Pauline, M, XD12345678, Fortis Dynamic 15/15, 2500,
USD,08-01-2009

case 4 : separator = '\",\"'

Applies for Camel 2.8.2 or older

When the field to be parsed of the CSV record contains ',' or ';' which is also used as separator, we whould find another strategy
to tell camel bindy how to handle this case. To define the field containing the data with a comma, you will use simple or double quotes
as delimiter (e.g : '10', 'Street 10, NY', 'USA' or "10", "Street 10, NY", "USA").
Remark : In this case, the first and last character of the line which are a simple or double quotes will removed by bindy

"10","J","Pauline"," M","XD12345678","Fortis Dynamic 15,15"
2500","USD","08-01-2009"

"10","J","Pauline"," M","XD12345678","Fortis Dynamic 15,15"

@CsvRecord( separator = "\",\"" )

public Class Order {

}

Copy to Clipboard

Toggle word wrap

From Camel 2.8.3/2.9 or never bindy will automatic detect if the record is enclosed with either single or double quotes and automatic remove those quotes when unmarshalling from CSV to Object. Therefore do not include the quotes in the separator, but simple do as below:

"10","J","Pauline"," M","XD12345678","Fortis Dynamic 15,15"
2500","USD","08-01-2009"

"10","J","Pauline"," M","XD12345678","Fortis Dynamic 15,15"

}

@CsvRecord( separator = "," )

Notice that if you want to marshal from Object to CSV and use quotes, then you need to specify which quote character to use, using the quote attribute on the @CsvRecord as shown below:

@CsvRecord( separator = ",", quote = "\"" )
public Class Order {

}

@CsvRecord( separator = ",", quote = "\"" )
public Class Order {

}

case 5 : separator & skipfirstline

The feature is interesting when the client wants to have in the first line of the file, the name of the data fields :

order id, client id, first name, last name, isin code, instrument name, quantity, currency, date

To inform bindy that this first line must be skipped during the parsing process, then we use the attribute :

@CsvRecord(separator = ",", skipFirstLine = true)
public Class Order {

}

@CsvRecord(separator = ",", skipFirstLine = true)
public Class Order {

}

Copy to Clipboard

Toggle word wrap

case 6 : generateHeaderColumns

To add at the first line of the CSV generated, the attribute generateHeaderColumns must be set to true in the annotation like this :

@CsvRecord( generateHeaderColumns = true )
public Class Order {

}

@CsvRecord( generateHeaderColumns = true )
public Class Order {

}

Copy to Clipboard

Toggle word wrap

As a result, Bindy during the unmarshaling process will generate CSV like this :

order id, client id, first name, last name, isin code, instrument name, quantity, currency, date

10, J, Pauline, M, XD12345678, Fortis Dynamic 15/15, 2500, USD,08-01-2009

case 7 : carriage return

If the platform where camel-bindy will run is not Windows but Macintosh or Unix, than you can change the crlf property like this. Three values are available : WINDOWS, UNIX or MAC

@CsvRecord(separator = ",", crlf="MAC")
public Class Order {

}

@CsvRecord(separator = ",", crlf="MAC")
public Class Order {

}

Copy to Clipboard

Toggle word wrap

Additionally, if for some reason you need to add a different line ending character, you can opt to specify it using the crlf parameter. In the following example, we can end the line with a comma followed by the newline character:

@CsvRecord(separator = ",", crlf=",\n")
public Class Order {

}

@CsvRecord(separator = ",", crlf=",\n")
public Class Order {

}

Copy to Clipboard

Toggle word wrap

case 8 : isOrdered

Sometimes, the order to follow during the creation of the CSV record from the model is different from the order used during the parsing. Then, in this case, we can use the attribute isOrdered = true to indicate this in combination with attribute 'position' of the DataField annotation.

@CsvRecord(isOrdered = true)
public Class Order {

   @DataField(pos = 1, position = 11)
   private int orderNr;

   @DataField(pos = 2, position = 10)
   private String clientNr;

}

@CsvRecord(isOrdered = true)
public Class Order {

   @DataField(pos = 1, position = 11)
   private int orderNr;

   @DataField(pos = 2, position = 10)
   private String clientNr;

}

Copy to Clipboard

Remark : pos is used to parse the file, stream while positions is used to generate the CSV

Expand

Annotation name	Record type	Level
DataField	all	Property

Expand

Parameter name	type	Info
pos	int	mandatory - The input position of the field. digit number starting from 1 to … - See the position parameter.
pattern	string	optional - default value = "" - will be used to format Decimal, Date,
length	int	optional - represents the length of the field for fixed length format
precision	int	optional - represents the precision to be used when the Decimal number will be formatted/parsed
pattern	string	optional - default value = "" - is used by the Java formatter (SimpleDateFormat by example) to format/validate data. If using pattern, then setting locale on bindy data format is recommended. Either set to a known locale such as "us" or use "default" to use platform default locale. Notice that "default" requires Camel 2.14/2.13.3/2.12.5.
position	int	optional - must be used when the position of the field in the CSV generated (output message) must be different compare to input position (pos). See the pos parameter.
required	boolean	optional - default value = "false"
trim	boolean	optional - default value = "false"
defaultValue	string	Camel 2.10: optional - default value = "" - defines the field’s default value when the respective CSV field is empty/not available
impliedDecimalSeparator	boolean	Camel 2.11: optional - default value = "false" - Indicates if there is a decimal point implied at a specified location
lengthPos	int	Camel 2.11: optional - can be used to identify a data field in a fixed-length record that defines the fixed length for this field
align	string	optional - default value = "R" - Align the text to the right or left within a fixed-length field. Use values 'R' or 'L'
delimiter	string	Camel 2.11: optional - can be used to demarcate the end of a variable-length field within a fixed-length record

case 1 : pos

This parameter/attribute represents the position of the field in the csv record

Position

@CsvRecord(separator = ",")
public class Order {

    @DataField(pos = 1)
    private int orderNr;

case 4 : Position is different in output

The position attribute will inform bindy how to place the field in the CSV record generated. By default, the position used corresponds to the position defined with the attribute 'pos'. If the position is different (that means that we have an asymetric processus comparing marshaling from unmarshaling) than we can use 'position' to indicate this.

Here is an example

Position is different in output

@CsvRecord(separator = ",", isOrdered = true)
public class Order {

    // Positions of the fields start from 1 and not from 0

    @DataField(pos = 1, position = 11)
    private int orderNr;

    @DataField(pos = 2, position = 10)
    private String clientNr;

    @DataField(pos = 3, position = 9)
    private String firstName;

    @DataField(pos = 4, position = 8)
    private String lastName;

    @DataField(pos = 5, position = 7)

48.6. 4. FixedLengthRecord
复制链接

The FixedLengthRecord annotation is used to identified the root class of the model. It represents a record = a line of a file/message containing data fixed length formatted and can be linked to several children model classes. This format is a bit particular beause data of a field can be aligned to the right or to the left.
When the size of the data does not fill completely the length of the field, we can then add 'padd' characters.

Annotation name	Record type	Level

Parameter name	type	Info
crlf	string	optional - possible values = WINDOWS,UNIX,MAC, or custom; default value. WINDOWS - allow to define the carriage return character to use. If you specify a value other than the three listed before, the value you enter (custom) will be used as the CRLF character(s). This option is used only during marshalling, whereas unmarshalling uses system default JDK provided line delimiter unless eol is customized
eol	string	optional - default="" which is empty string. Character to be used to process considering end of line after each record while unmarshalling (optional - default = "" which help default JDK provided line delimiter to be used unless any other line delimiter provided). This option is used only during unmarshalling, where marshalling uses system default provided line delimiter as "WINDOWS" unless any other value is provided
paddingChar	char	mandatory - default value = ' '
length	int	mandatory = size of the fixed length record
hasHeader	boolean	Camel 2.11 - optional - Indicates that the record(s) of this type may be preceded by a single header record at the beginning of the file / stream
hasFooter	boolean	Camel 2.11 - optional - Indicates that the record(s) of this type may be followed by a single footer record at the end of the file / stream
skipHeader	boolean	Camel 2.11 - optional - Configures the data format to skip marshalling / unmarshalling of the header record. Configure this parameter on the primary record (e.g., not the header or footer).
skipFooter	boolean	Camel 2.11 - optional - Configures the data format to skip marshalling / unmarshalling of the footer record Configure this parameter on the primary record (e.g., not the header or footer)..
isHeader	boolean	Camel 2.11 - optional - Identifies this FixedLengthRecord as a header record
isFooter	boolean	Camel 2.11 - optional - Identifies this FixedLengthRecords as a footer record
ignoreTrailingChars	boolean	Camel 2.11.1 - optional - Indicates that characters beyond the last mapped filed can be ignored when unmarshalling / parsing. This annotation is associated to the root class of the model and must be declared one time.

The hasHeader/hasFooter parameters are mutually exclusive with isHeader/isFooter. A record may not be both a header/footer and a primary fixed-length record.

case 3 : Field padding

Sometimes, the default padding defined for record cannnot be applied to the field as we have a number format where we would like to padd with '0' instead of ' '. In this case, you can use in the model the attribute paddingField to set this value.

case 7 : Skipping content when parsing a fixed length record. (Camel 2.11.1)

It is common to integrate with systems that provide fixed-length records containing more information than needed for the target use case. It is useful in this situation to skip the declaration and parsing of those fields that we do not need. To accomodate this, Bindy will skip forward to the next mapped field within a record if the 'pos' value of the next declared field is beyond the cursor position of the last parsed field. Using absolute 'pos' locations for the fields of interest (instead of ordinal values) causes Bindy to skip content between two fields.

Similarly, it is possible that none of the content beyond some field is of interest. In this case, you can tell Bindy to skip parsing of everything beyond the last mapped field by setting the ignoreTrailingChars property on the @FixedLengthRecord declaration.

@FixedLengthRecord(ignoreTrailingChars = true)
public static class Order {

    @DataField(pos = 1, length = 2)
    private int orderNr;

    @DataField(pos = 3, length = 2)
    private String clientNr;

    // any characters that appear beyond the last mapped field will be ignored

}

@FixedLengthRecord(ignoreTrailingChars = true)
public static class Order {

    @DataField(pos = 1, length = 2)
    private int orderNr;

    @DataField(pos = 3, length = 2)
    private String clientNr;

    // any characters that appear beyond the last mapped field will be ignored

48.7. 5. Message
复制链接

The Message annotation is used to identified the class of your model who will contain key value pairs fields. This kind of format is used mainly in Financial Exchange Protocol Messages (FIX). Nevertheless, this annotation can be used for any other format where data are identified by keys. The key pair values are separated each other by a separator which can be a special character like a tab delimitor (unicode representation : \u0009) or a start of heading (unicode representation : \u0001)

More information about FIX can be found on this web site : http://www.fixprotocol.org/. To work with FIX messages, the model must contain a Header and Trailer classes linked to the root message class which could be a Order class. This is not mandatory but will be very helpful when you will use camel-bindy in combination with camel-fix which is a Fix gateway based on quickFix project http://www.quickfixj.org/.

Expand

Annotation name	Record type	Level
Message	key value pair	Class

Expand

Parameter name	type	Info
pairSeparator	string	mandatory - can be '=' or ';' or 'anything'
keyValuePairSeparair	string	mandatory - can be '\u0001', '\u0009', '#' or 'anything'
crlf	string	optional - possible values = WINDOWS,UNIX,MAC, or custom; default value = WINDOWS - allow to define the carriage return character to use. If you specify a value other than the three listed before, the value you enter (custom) will be used as the CRLF character(s)
type	string	optional - define the type of message (e.g. FIX, EMX, …)
version	string	optional - version of the message (e.g. 4.1)
isOrdered	boolean	optional - default value = false - allow to change the order of the fields when FIX message is generated. This annotation is associated to the message class of the model and must be declared one time.

case 1 : separator = 'u0001'

The separator used to segregate the key value pair fields in a FIX message is the ASCII '01' character or in unicode format '\u0001'. This character must be escaped a second time to avoid a java runtime error. Here is an example :

8=FIX.4.1 9=20 34=1 35=0 49=INVMGR 56=BRKR 1=BE.CHM.001 11=CHM0001-01

The DefaultFormatFactory makes formatting of the following datatype available by returning an instance of the interface FormatFactoryInterface based on the provided FormattingOptions:

BigDecimal
BigInteger
Boolean
Byte
Character
Date
Double
Enums
Float
Integer
LocalDate (java 8, since 2.18.0)
LocalDateTime (java 8, since 2.18.0)
LocalTime (java 8, since 2.18.0)
Long
Short
String

The DefaultFormatFactory can be overridden by providing an instance of FactoryRegistry in the registry in use (e.g. spring or JNDI).

48.14. Using the Java DSL
复制链接

The next step consists in instantiating the DataFormat bindy class associated with this record type and providing Java package name(s) as parameter.

For example the following uses the class BindyCsvDataFormat (who correspond to the class associated with the CSV record type) which is configured with com.acme.model package name to initialize the model objects configured in this package.

// Camel 2.15 or older (configure by package name)
DataFormat bindy = new BindyCsvDataFormat("com.acme.model");

 
// Camel 2.16 onwards (configure by class name)
DataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

// Camel 2.15 or older (configure by package name)
DataFormat bindy = new BindyCsvDataFormat("com.acme.model");

 
// Camel 2.16 onwards (configure by class name)
DataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

48.14.1. Setting locale

Bindy supports configuring the locale on the dataformat, such as

// Camel 2.15 or older (configure by package name)

// Camel 2.16 onwards (configure by class name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

bindy.setLocale("us");

// Camel 2.15 or older (configure by package name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat("com.acme.model");
// Camel 2.16 onwards (configure by class name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

bindy.setLocale("us");

Copy to Clipboard

Or to use the platform default locale then use "default" as the locale name. Notice this requires Camel 2.14/2.13.3/2.12.5.

// Camel 2.15 or older (configure by package name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat("com.acme.model");
// Camel 2.16 onwards (configure by class name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

bindy.setLocale("default");

// Camel 2.15 or older (configure by package name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat("com.acme.model");
// Camel 2.16 onwards (configure by class name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

for older releases you can set it using Java code as shown

// Camel 2.15 or older (configure by package name)

BindyCsvDataFormat bindy = new BindyCsvDataFormat(com.acme.model.MyModel.class);

bindy.setLocale(Locale.getDefault().getISO3Country());

// Camel 2.15 or older (configure by package name)
BindyCsvDataFormat bindy = new BindyCsvDataFormat("com.acme.model");
// Camel 2.16 onwards (configure by class name)

Alternatively, you can use a named reference to a data format which can then be defined in your Registry e.g. your Spring XML file:

from("file://inbox")
  .unmarshal("myBindyDataFormat")
  .to("direct:handleOrders");

from("file://inbox")
  .unmarshal("myBindyDataFormat")

Toggle word wrap

The Camel route will pick-up files in the inbox directory, unmarshall CSV records into a collection of model objects and send the collection
to the route referenced by 'handleOrders'.

The collection returned is a List of Map objects. Each Map within the list contains the model objects that were marshalled out of each line of the CSV. The reason behind this is that each line can correspond to more than one object. This can be confusing when you simply expect one object to be returned per line.

Each object can be retrieve using its class name.

List<Map<String, Object>> unmarshaledModels = (List<Map<String, Object>>) exchange.getIn().getBody();

int modelCount = 0;
for (Map<String, Object> model : unmarshaledModels) {
  for (String className : model.keySet()) {
     Object obj = model.get(className);
     LOG.info("Count : " + modelCount + ", " + obj.toString());
  }
 modelCount++;
}

LOG.info("Total CSV records received by the csv bean : " + modelCount);

List<Map<String, Object>> unmarshaledModels = (List<Map<String, Object>>) exchange.getIn().getBody();

int modelCount = 0;
for (Map<String, Object> model : unmarshaledModels) {
  for (String className : model.keySet()) {
     Object obj = model.get(className);
     LOG.info("Count : " + modelCount + ", " + obj.toString());
  }
 modelCount++;
}

Assuming that you want to extract a single Order object from this map for processing in a route, you could use a combination of a Splitter and a Processor as per the following:

from("file://inbox")
    .unmarshal(bindy)
    .split(body())
        .process(new Processor() {

Take care of the fact that Bindy uses CHARSET_NAME property or the CHARSET_NAME header as define in the Exchange interface to do a characterset conversion of the inputstream received for unmarshalling. In some producers (e.g. file-endpoint) you can define a characterset. The characterset conversion can already been done by this producer. Sometimes you need to remove this property or header from the exchange before sending it to the unmarshal. If you don’t remove it the conversion might be done twice which might lead to unwanted results.

from("file://inbox?charset=Cp922")
  .removeProperty(Exchange.CHARSET_NAME)
  .unmarshal("myBindyDataFormat")
  .to("direct:handleOrders");

from("file://inbox?charset=Cp922")
  .removeProperty(Exchange.CHARSET_NAME)
  .unmarshal("myBindyDataFormat")
  .to("direct:handleOrders");

To generate CSV records from a collection of model objects, you create the following route :

from("direct:handleOrders")
   .marshal(bindy)
   .to("file://outbox")

from("direct:handleOrders")
   .marshal(bindy)
   .to("file://outbox")

48.15. Using Spring XML
复制链接

This is really easy to use Spring as your favorite DSL language to declare the routes to be used for camel-bindy. The following example shows two routes where the first will pick-up records from files, unmarshal the content and bind it to their model. The result is then send to a pojo (doing nothing special) and place them into a queue.

The second route will extract the pojos from the queue and marshal the content to generate a file containing the csv record. The example above is for using Camel 2.16 onwards.

To use Bindy in your camel routes you need to add the a dependency on camel-bindy which implements this data format.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-bindy</artifactId>

Chapter 49. Using OSGi blueprint with Camel
复制链接

A custom XML namespace for Blueprint has been created to let you leverage the nice XML dialect. Given Blueprint custom namespaces are not standardized yet, this namespace can only be used on the Apache Aries Blueprint implementation, which is the one used by Apache Karaf.

49.1. Overview
复制链接

The XML schema is mostly the same as the one for Spring, so all the xml snippets throughout the documentation referring to Spring XML also apply to Blueprint routes.

Here is a very simple route definition using blueprint:

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="timer:test" />
            <to uri="log:test" />
        </route>
    </camelContext>

</blueprint>

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="timer:test" />
            <to uri="log:test" />
        </route>
    </camelContext>

</blueprint>

Copy to Clipboard

Toggle word wrap

There are a few limitations at this point about the supported xml elements (compared to the Spring xml syntax):

beanPostProcessor are specific to Spring and aren’t allowed

However, using blueprint when you deploy your applications in an OSGi enviroment has several advantages:

when upgrading to a new camel version, you don’t have to change the namespace, as the correct version will be selected based on the camel packages that are imported by your bundle
no startup ordering issue with respect to the custom namespaces and your bundles
you can use Blueprint property placeholders

49.2. Using camel-blueprint
复制链接

To leverage camel-blueprint in OSGi, you only need the Aries Blueprint bundle and the camel-blueprint bundle, in addition to camel-core and its dependencies.

If you use Karaf, you can use the feature named camel-blueprint which will install all the required bundles.

Chapter 52. Box Component
复制链接

Available as of Camel version 2.14

The Box component provides access to all of the Box.com APIs accessible using https://github.com/box/box-java-sdk. It allows producing messages to upload and download files, create, edit, and manage folders, etc. It also supports APIs that allow polling for updates to user accounts and even changes to enterprise accounts, etc.

Box.com requires the use of OAuth2.0 for all client application authentication. In order to use camel-box with your account, you’ll need to create a new application within Box.com at https://developer.box.com. The Box application’s client id and secret will allow access to Box APIs which require a current user. A user access token is generated and managed by the API for an end user.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-box</artifactId>
    <version>${camel-version}</version>

52.4. Producer Endpoints:
复制链接

Producer endpoints can use endpoint prefixes followed by endpoint names and associated options described next. A shorthand alias can be used for some endpoints. The endpoint URI MUST contain a prefix.

Endpoint options that are not mandatory are denoted by []. When there are no mandatory options for an endpoint, one of the set of [] options MUST be provided. Producer endpoints can also use a special option inBody that in turn should contain the name of the endpoint option whose value will be contained in the Camel Exchange In message.

Any of the endpoint options can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelBox.<option>. Note that the inBody option overrides message header, i.e. the endpoint option inBody=option would override a CamelBox.option header.

If a value is not provided for the option defaultRequest either in the endpoint URI or in a message header, it will be assumed to be null. Note that the null value will only be used if other options do not satisfy matching endpoints.

In case of Box API errors the endpoint will throw a RuntimeCamelException with a com.box.sdk.BoxAPIException derived exception cause.

53.4. Producer Endpoints:
复制链接

Producer endpoints can use endpoint prefixes followed by endpoint names and associated options described next. A shorthand alias can be used for some endpoints. The endpoint URI MUST contain a prefix.

Endpoint options that are not mandatory are denoted by []. When there are no mandatory options for an endpoint, one of the set of [] options MUST be provided. Producer endpoints can also use a special option inBody that in turn should contain the name of the endpoint option whose value will be contained in the Camel Exchange In message.

Any of the endpoint options can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelBraintree.<option>. Note that the inBody option overrides message header, i.e. the endpoint option inBody=option would override a CamelBraintree.option header.

    BrowsableEndpoint browse = context.getEndpoint("browse:orderReceived", BrowsableEndpoint.class);
    List<Exchange> exchanges = browse.getExchanges();

    // then we can inspect the list of received exchanges from Java
    for (Exchange exchange : exchanges) {
        String payload = exchange.getIn().getBody();
        // do something with payload
    }
}

Chapter 55. EHCache Component (deprecated)
复制链接

Available as of Camel version 2.1

The cache component enables you to perform caching operations using EHCache as the Cache Implementation. The cache itself is created on demand or if a cache of that name already exists then it is simply utilized with its original settings.

This component supports producer and event based consumer endpoints.

The Cache consumer is an event based consumer and can be used to listen and respond to specific cache activities. If you need to perform selections from a pre-existing cache, use the processors defined for the cache component.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-cache</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->

55.3. Sending/Receiving Messages to/from the cache
复制链接

55.3.1. Message Headers up to Camel 2.7
复制链接

Expand

Header Description

CACHE_OPERATION

The operation to be performed on the cache. Valid options are

* GET * CHECK * ADD * UPDATE * DELETE * DELETEALL
GET and CHECK requires Camel 2.3 onwards.

CACHE_KEY

The cache key used to store the Message in the cache. The cache key is optional if the CACHE_OPERATION is DELETEALL

55.3.2. Message Headers Camel 2.8+
复制链接

Header changes in Camel 2.8

The header names and supported values have changed to be prefixed with 'CamelCache' and use mixed case. This makes them easier to identify and keep separate from other headers. The CacheConstants variable names remain unchanged, just their values have been changed. Also, these headers are now removed from the exchange after the cache operation is performed.

Expand

Header Description

CamelCacheOperation

The operation to be performed on the cache. The valid options are

* CamelCacheGet * CamelCacheCheck * CamelCacheAdd * CamelCacheUpdate * CamelCacheDelete * CamelCacheDeleteAll

CamelCacheKey

The cache key used to store the Message in the cache. The cache key is optional if the CamelCacheOperation is CamelCacheDeleteAll

The CamelCacheAdd and CamelCacheUpdate operations support additional headers:

Expand

Header	Type	Description
`CamelCacheTimeToLive`	`Integer`	Camel 2.11: Time to live in seconds.
`CamelCacheTimeToIdle`	`Integer`	Camel 2.11: Time to idle in seconds.
`CamelCacheEternal`	`Boolean`	Camel 2.11: Whether the content is eternal.

55.3.3. Cache Producer
复制链接

Sending data to the cache involves the ability to direct payloads in exchanges to be stored in a pre-existing or created-on-demand cache. The mechanics of doing this involve

setting the Message Exchange Headers shown above.
ensuring that the Message Exchange Body contains the message directed to the cache

55.3.4. Cache Consumer
复制链接

Receiving data from the cache involves the ability of the CacheConsumer to listen on a pre-existing or created-on-demand Cache using an event Listener and receive automatic notifications when any cache activity take place (i.e CamelCacheGet/CamelCacheUpdate/CamelCacheDelete/CamelCacheDeleteAll). Upon such an activity taking place

an exchange containing Message Exchange Headers and a Message Exchange Body containing the just added/updated payload is placed and sent.
in case of a CamelCacheDeleteAll operation, the Message Exchange Header CamelCacheKey and the Message Exchange Body are not populated.

55.3.5. Cache Processors

Here’s a snippet on how to expose them via JMX in a Spring application context:

<bean id="ehCacheManagementService" class="net.sf.ehcache.management.ManagementService" init-method="init" lazy-init="false">
  <constructor-arg>
    <bean class="net.sf.ehcache.CacheManager" factory-method="getInstance"/>
  </constructor-arg>
  <constructor-arg>
    <bean class="org.springframework.jmx.support.JmxUtils" factory-method="locateMBeanServer"/>
  </constructor-arg>
  <constructor-arg value="true"/>
  <constructor-arg value="true"/>
  <constructor-arg value="true"/>
  <constructor-arg value="true"/>
</bean>

<bean id="ehCacheManagementService" class="net.sf.ehcache.management.ManagementService" init-method="init" lazy-init="false">
  <constructor-arg>
    <bean class="net.sf.ehcache.CacheManager" factory-method="getInstance"/>
  </constructor-arg>
  <constructor-arg>
    <bean class="org.springframework.jmx.support.JmxUtils" factory-method="locateMBeanServer"/>
  </constructor-arg>
  <constructor-arg value="true"/>
  <constructor-arg value="true"/>
  <constructor-arg value="true"/>
  <constructor-arg value="true"/>
</bean>

Of course you can do the same thing in straight Java:

ManagementService.registerMBeans(CacheManager.getInstance(), mbeanServer, true, true, true, true);

ManagementService.registerMBeans(CacheManager.getInstance(), mbeanServer, true, true, true, true);

You can get cache hits, misses, in-memory hits, disk hits, size stats this way. You can also change CacheConfiguration parameters on the fly.

55.6. Cache replication Camel 2.8
复制链接

The Camel Cache component is able to distribute a cache across server nodes using several different replication mechanisms including: RMI, JGroups, JMS and Cache Server.

There are two different ways to make it work:

1. You can configure ehcache.xml manually

OR

2. You can configure these three options:

cacheManagerFactory
eventListenerRegistry
cacheLoaderRegistry

Configuring Camel Cache replication using the first option is a bit of hard work as you have to configure all caches separately. So in a situation when the all names of caches are not known, using ehcache.xml is not a good idea.

The second option is much better when you want to use many different caches as you do not need to define options per cache. This is because replication options are set per CacheManager and per CacheEndpoint. Also it is the only way when cache names are not know at the development phase.

Note: It might be useful to read the EHCache manual to get a better understanding of the Camel Cache replication mechanism.

55.6.1. Example: JMS cache replication
复制链接

JMS replication is the most powerful and secured replication method. Used together with Camel Cache replication makes it also rather simple. An example is available on a separate page.

Chapter 58. Castor DataFormat (deprecated)
复制链接

Available as of Camel version 2.1

Castor is a Data Format which uses the Castor XML library to unmarshal an XML payload into Java objects or to marshal Java objects into an XML payload.

As usually you can use either Java DSL or Spring XML to work with Castor Data Format.

58.1. Using the Java DSL

  marshal().castor().
  to("activemq:queue:order");

from("direct:order").

For example the following uses a named DataFormat of Castor which uses default Castor data binding features.

CastorDataFormat castor = new CastorDataFormat ();

from("activemq:My.Queue").
  unmarshal(castor).
  to("mqseries:Another.Queue");

CastorDataFormat castor = new CastorDataFormat ();

from("activemq:My.Queue").
  unmarshal(castor).
  to("mqseries:Another.Queue");

Copy to Clipboard

Toggle word wrap

If you prefer to use a named reference to a data format which can then be defined in your Registry such as via your Spring XML file. e.g.

from("activemq:My.Queue").
  unmarshal("mycastorType").
  to("mqseries:Another.Queue");

from("activemq:My.Queue").
  unmarshal("mycastorType").
  to("mqseries:Another.Queue");

If you want to override default mapping schema by providing a mapping file you can set it as follows.

CastorDataFormat castor = new CastorDataFormat ();
castor.setMappingFile("mapping.xml");

CastorDataFormat castor = new CastorDataFormat ();
castor.setMappingFile("mapping.xml");

Chapter 59. Camel CDI
复制链接

The Camel CDI component provides auto-configuration for Apache Camel using CDI as dependency injection framework based on convention-over-configuration. It auto-detects Camel routes available in the application and provides beans for common Camel primitives like Endpoint, FluentProducerTemplate, ProducerTemplate or TypeConverter. It implements standard Camel bean integration so that Camel annotations like @Consume, @Produce and @PropertyInject can be used seamlessly in CDI beans. Besides, it bridges Camel events (e.g. RouteAddedEvent, CamelContextStartedEvent, ExchangeCompletedEvent, …) as CDI events and provides a CDI events endpoint that can be used to consume / produce CDI events from / to Camel routes.

While the Camel CDI component is available as of Camel 2.10, it’s been rewritten in Camel 2.17 to better fit into the CDI programming model. Hence some of the features like the Camel events to CDI events bridge and the CDI events endpoint only apply starting Camel 2.17.

More details on how to test Camel CDI applications are available in Camel CDI testing.

Important

camel-cdi is deprecated in OSGi and not supported. Use OSGi Blueprint if using Camel with OSGi.

59.1. Auto-configured Camel context
复制链接

Camel CDI automatically deploys and configures a CamelContext bean. That CamelContext bean is automatically instantiated, configured and started (resp. stopped) when the CDI container initializes (resp. shuts down). It can be injected in the application, e.g.:

@Inject
CamelContext context;

@Inject
CamelContext context;

Copy to Clipboard

Toggle word wrap

That default CamelContext bean is qualified with the built-in @Default qualifier, is scoped @ApplicationScoped and is of type DefaultCamelContext.

Note that this bean can be customized programmatically and other Camel context beans can be deployed in the application as well.

59.2. Auto-detecting Camel routes
复制链接

Camel CDI automatically collects all the RoutesBuilder beans in the application, instantiates and add them to the CamelContext bean instance when the CDI container initializes. For example, adding a Camel route is as simple as declaring a class, e.g.:

class MyRouteBean extends RouteBuilder {
 
    @Override
    public void configure() {
        from("jms:invoices").to("file:/invoices");
    }
}

class MyRouteBean extends RouteBuilder {
 
    @Override
    public void configure() {
        from("jms:invoices").to("file:/invoices");
    }
}

Copy to Clipboard

Toggle word wrap

Note that you can declare as many RoutesBuilder beans as you want. Besides, RouteContainer beans are also automatically collected, instantiated and added to the CamelContext bean instance managed by Camel CDI when the container initializes.

Available as of Camel 2.19

In some situations, it may be necessary to disable the auto-configuration of the RouteBuilder and RouteContainer beans. That can be achieved by observing for the CdiCamelConfiguration event, e.g.:

static void configuration(@Observes CdiCamelConfiguration configuration) {
    configuration.autoConfigureRoutes(false);
}

static void configuration(@Observes CdiCamelConfiguration configuration) {
    configuration.autoConfigureRoutes(false);
}

Copy to Clipboard

Toggle word wrap

Similarly, it is possible to deactivate the automatic starting of the configured CamelContext beans, e.g.:

static void configuration(@Observes CdiCamelConfiguration configuration) {
    configuration.autoStartContexts(false);
}

static void configuration(@Observes CdiCamelConfiguration configuration) {
    configuration.autoStartContexts(false);
}

59.3. Auto-configured Camel primitives
复制链接

Camel CDI provides beans for common Camel primitives that can be injected in any CDI beans, e.g.:

@Inject
@Uri("direct:inbound")
ProducerTemplate producerTemplate;

@Inject
@Uri("direct:inbound")
FluentProducerTemplate fluentProducerTemplate;

@Inject
MockEndpoint outbound; // URI defaults to the member name, i.e. mock:outbound

@Inject
@Uri("direct:inbound")
Endpoint endpoint;

@Inject
TypeConverter converter;

@Inject
@Uri("direct:inbound")
ProducerTemplate producerTemplate;

@Inject
@Uri("direct:inbound")
FluentProducerTemplate fluentProducerTemplate;

@Inject
MockEndpoint outbound; // URI defaults to the member name, i.e. mock:outbound

@Inject
@Uri("direct:inbound")
Endpoint endpoint;

@Inject
TypeConverter converter;

59.4. Camel context configuration
复制链接

If you just want to change the name of the default CamelContext bean, you can used the @ContextName qualifier provided by Camel CDI, e.g.:

@ContextName("camel-context")
class MyRouteBean extends RouteBuilder {
 
    @Override
    public void configure() {
        from("jms:invoices").to("file:/invoices");
    }
}

@ContextName("camel-context")
class MyRouteBean extends RouteBuilder {
 
    @Override
    public void configure() {
        from("jms:invoices").to("file:/invoices");
    }
}

Copy to Clipboard

Toggle word wrap

Else, if more customization is needed, any CamelContext class can be used to declare a custom Camel context bean. Then, the @PostConstruct and @PreDestroy lifecycle callbacks can be done to do the customization, e.g.:

@ApplicationScoped
class CustomCamelContext extends DefaultCamelContext {

    @PostConstruct
    void customize() {
        // Set the Camel context name
        setName("custom");
        // Disable JMX
        disableJMX();
    }

    @PreDestroy
    void cleanUp() {
        // ...
    }
}

@ApplicationScoped
class CustomCamelContext extends DefaultCamelContext {

    @PostConstruct
    void customize() {
        // Set the Camel context name
        setName("custom");
        // Disable JMX
        disableJMX();
    }

    @PreDestroy
    void cleanUp() {
        // ...
    }
}

Copy to Clipboard

Toggle word wrap

Producer and disposer methods can also be used as well to customize the Camel context bean, e.g.:

class CamelContextFactory {

    @Produces
    @ApplicationScoped
    CamelContext customize() {
        DefaultCamelContext context = new DefaultCamelContext();
        context.setName("custom");
        return context;
    }

    void cleanUp(@Disposes CamelContext context) {
        // ...
    }
}

class CamelContextFactory {

    @Produces
    @ApplicationScoped
    CamelContext customize() {
        DefaultCamelContext context = new DefaultCamelContext();
        context.setName("custom");
        return context;
    }

    void cleanUp(@Disposes CamelContext context) {
        // ...
    }
}

Copy to Clipboard

Toggle word wrap

Similarly, producer fields can be used, e.g.:

@Produces
@ApplicationScoped
CamelContext context = new CustomCamelContext();

class CustomCamelContext extends DefaultCamelContext {

    CustomCamelContext() {
        setName("custom");
    }
}

@Produces
@ApplicationScoped
CamelContext context = new CustomCamelContext();

class CustomCamelContext extends DefaultCamelContext {

    CustomCamelContext() {
        setName("custom");
    }
}

Copy to Clipboard

Toggle word wrap

This pattern can be used for example to avoid having the Camel context routes started automatically when the container initializes by calling the setAutoStartup method, e.g.:

@ApplicationScoped
class ManualStartupCamelContext extends DefaultCamelContext {

    @PostConstruct
    void manual() {
        setAutoStartup(false);
    }
}

@ApplicationScoped
class ManualStartupCamelContext extends DefaultCamelContext {

    @PostConstruct
    void manual() {
        setAutoStartup(false);
    }
}

59.5. Multiple Camel contexts
复制链接

Any number of CamelContext beans can actually be declared in the application as documented above. In that case, the CDI qualifiers declared on these CamelContext beans are used to bind the Camel routes and other Camel primitives to the corresponding Camel contexts. From example, if the following beans get declared:

@ApplicationScoped
@ContextName("foo")
class FooCamelContext extends DefaultCamelContext {
}

@ApplicationScoped
@BarContextQualifier
class BarCamelContext extends DefaultCamelContext {
}
 
@ContextName("foo")
class RouteAddedToFooCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}
 
@BarContextQualifier
class RouteAddedToBarCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}
 
@ContextName("baz")
class RouteAddedToBazCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}
 
@MyOtherQualifier
class RouteNotAddedToAnyCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}

@ApplicationScoped
@ContextName("foo")
class FooCamelContext extends DefaultCamelContext {
}

@ApplicationScoped
@BarContextQualifier
class BarCamelContext extends DefaultCamelContext {
}
 
@ContextName("foo")
class RouteAddedToFooCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}
 
@BarContextQualifier
class RouteAddedToBarCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}
 
@ContextName("baz")
class RouteAddedToBazCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}
 
@MyOtherQualifier
class RouteNotAddedToAnyCamelContext extends RouteBuilder {

    @Override
    public void configure() {
        // ...
    }
}

Copy to Clipboard

Toggle word wrap

The RoutesBuilder beans qualified with @ContextName are automatically added to the corresponding CamelContext beans by Camel CDI. If no such CamelContext bean exists, it gets automatically created, as for the RouteAddedToBazCamelContext bean. Note this only happens for the @ContextName qualifier provided by Camel CDI. Hence the RouteNotAddedToAnyCamelContext bean qualified with the user-defined @MyOtherQualifier qualifier does not get added to any Camel contexts. That may be useful, for example, for Camel routes that may be required to be added later during the application execution.

Note

Since Camel version 2.17.0, Camel CDI is capable of managing any kind of CamelContext beans (e.g. DefaultCamelContext). In previous versions, it is only capable of managing beans of type CdiCamelContext so it is required to extend it.

The CDI qualifiers declared on the CamelContext beans are also used to bind the corresponding Camel primitives, e.g.:

@Inject
@ContextName("foo")
@Uri("direct:inbound")
ProducerTemplate producerTemplate;

@Inject
@ContextName("foo")
@Uri("direct:inbound")
FluentProducerTemplate fluentProducerTemplate;

@Inject
@BarContextQualifier
MockEndpoint outbound; // URI defaults to the member name, i.e. mock:outbound

@Inject
@ContextName("baz")
@Uri("direct:inbound")
Endpoint endpoint;

@Inject
@ContextName("foo")
@Uri("direct:inbound")
ProducerTemplate producerTemplate;

@Inject
@ContextName("foo")
@Uri("direct:inbound")
FluentProducerTemplate fluentProducerTemplate;

@Inject
@BarContextQualifier
MockEndpoint outbound; // URI defaults to the member name, i.e. mock:outbound

59.6. Configuration properties
复制链接

To configure the sourcing of the configuration properties used by Camel to resolve properties placeholders, you can declare a PropertiesComponent bean qualified with @Named("properties"), e.g.:

@Produces
@ApplicationScoped
@Named("properties")
PropertiesComponent propertiesComponent() {
    Properties properties = new Properties();
    properties.put("property", "value");
    PropertiesComponent component = new PropertiesComponent();
    component.setInitialProperties(properties);
    component.setLocation("classpath:placeholder.properties");
    return component;
}

@Produces
@ApplicationScoped
@Named("properties")
PropertiesComponent propertiesComponent() {
    Properties properties = new Properties();
    properties.put("property", "value");
    PropertiesComponent component = new PropertiesComponent();
    component.setInitialProperties(properties);
    component.setLocation("classpath:placeholder.properties");
    return component;
}

If you want to use DeltaSpike configuration mechanism you can declare the following PropertiesComponent bean:

@Produces
@ApplicationScoped
@Named("properties")
PropertiesComponent properties(PropertiesParser parser) {
    PropertiesComponent component = new PropertiesComponent();
    component.setPropertiesParser(parser);
    return component;
}

// PropertiesParser bean that uses DeltaSpike to resolve properties
static class DeltaSpikeParser extends DefaultPropertiesParser {
    @Override
    public String parseProperty(String key, String value, Properties properties) {
        return ConfigResolver.getPropertyValue(key);
    }
}

@Produces
@ApplicationScoped
@Named("properties")
PropertiesComponent properties(PropertiesParser parser) {
    PropertiesComponent component = new PropertiesComponent();
    component.setPropertiesParser(parser);
    return component;
}

// PropertiesParser bean that uses DeltaSpike to resolve properties
static class DeltaSpikeParser extends DefaultPropertiesParser {
    @Override
    public String parseProperty(String key, String value, Properties properties) {
        return ConfigResolver.getPropertyValue(key);

CDI beans annotated with the @Converter annotation are automatically registered into the deployed Camel contexts, e.g.:

@Converter
public class MyTypeConverter {

    @Converter
    public Output convert(Input input) {
        //...
    }
}

@Converter
public class MyTypeConverter {

Available as of Camel 2.17

Camel provides a set of management events that can be subscribed to for listening to Camel context, service, route and exchange events. Camel CDI seamlessly translates these Camel events into CDI events that can be observed using CDI observer methods, e.g.:

void onContextStarting(@Observes CamelContextStartingEvent event) {
    // Called before the default Camel context is about to start
}

void onContextStarting(@Observes CamelContextStartingEvent event) {
    // Called before the default Camel context is about to start
}

As of Camel 2.18, it is possible to observe events for a particular route (RouteAddedEvent, RouteStartedEvent, RouteStoppedEvent and RouteRemovedEvent) should it have an explicit defined, e.g.:

from("...").routeId("foo").to("...");

void onRouteStarted(@Observes @Named("foo") RouteStartedEvent event) {
    // Called after the route "foo" has started
}

from("...").routeId("foo").to("...");

void onRouteStarted(@Observes @Named("foo") RouteStartedEvent event) {
    // Called after the route "foo" has started
}

Copy to Clipboard

Toggle word wrap

When multiple Camel contexts exist in the CDI container, the Camel context bean qualifiers, like @ContextName, can be used to refine the observer method resolution to a particular Camel context as specified in observer resolution, e.g.:

void onRouteStarted(@Observes @ContextName("foo") RouteStartedEvent event) {
    // Called after the route 'event.getRoute()' for the Camel context 'foo' has started
}
 
void onContextStarted(@Observes @Manual CamelContextStartedEvent event) {
    // Called after the the Camel context qualified with '@Manual' has started
}

void onRouteStarted(@Observes @ContextName("foo") RouteStartedEvent event) {
    // Called after the route 'event.getRoute()' for the Camel context 'foo' has started
}
 
void onContextStarted(@Observes @Manual CamelContextStartedEvent event) {
    // Called after the the Camel context qualified with '@Manual' has started
}

Copy to Clipboard

Toggle word wrap

Similarly, the @Default qualifier can be used to observe Camel events for the default Camel context if multiples contexts exist, e.g.:

void onExchangeCompleted(@Observes @Default ExchangeCompletedEvent event) {
    // Called after the exchange 'event.getExchange()' processing has completed
}

void onExchangeCompleted(@Observes @Default ExchangeCompletedEvent event) {
    // Called after the exchange 'event.getExchange()' processing has completed
}

Copy to Clipboard

Toggle word wrap

In that example, if no qualifier is specified, the @Any qualifier is implicitly assumed, so that corresponding events for all the Camel contexts get received.

Note that the support for Camel events translation into CDI events is only activated if observer methods listening for Camel events are detected in the deployment, and that per Camel context.

59.10. CDI events endpoint
复制链接

Available as of Camel 2.17

The CDI event endpoint bridges the CDI events with the Camel routes so that CDI events can be seamlessly observed / consumed (resp. produced / fired) from Camel consumers (resp. by Camel producers).

The CdiEventEndpoint<T> bean provided by Camel CDI can be used to observe / consume CDI events whose event type is T, for example:

@Inject
CdiEventEndpoint<String> cdiEventEndpoint;

from(cdiEventEndpoint).log("CDI event received: ${body}");

@Inject
CdiEventEndpoint<String> cdiEventEndpoint;

from(cdiEventEndpoint).log("CDI event received: ${body}");

Copy to Clipboard

Toggle word wrap

This is equivalent to writing:

@Inject
@Uri("direct:event")
ProducerTemplate producer;

void observeCdiEvents(@Observes String event) {
    producer.sendBody(event);
}

from("direct:event").log("CDI event received: ${body}");

@Inject
@Uri("direct:event")
ProducerTemplate producer;

void observeCdiEvents(@Observes String event) {
    producer.sendBody(event);
}

from("direct:event").log("CDI event received: ${body}");

Copy to Clipboard

Toggle word wrap

Conversely, the CdiEventEndpoint<T> bean can be used to produce / fire CDI events whose event type is T, for example:

@Inject
CdiEventEndpoint<String> cdiEventEndpoint;

from("direct:event").to(cdiEventEndpoint).log("CDI event sent: ${body}");

@Inject
CdiEventEndpoint<String> cdiEventEndpoint;

from("direct:event").to(cdiEventEndpoint).log("CDI event sent: ${body}");

Copy to Clipboard

Toggle word wrap

This is equivalent to writing:

@Inject
Event<String> event;

from("direct:event").process(new Processor() {
    @Override
    public void process(Exchange exchange) {
        event.fire(exchange.getBody(String.class));
    }
}).log("CDI event sent: ${body}");

@Inject
Event<String> event;

from("direct:event").process(new Processor() {
    @Override
    public void process(Exchange exchange) {
        event.fire(exchange.getBody(String.class));
    }
}).log("CDI event sent: ${body}");

Or using a Java 8 lambda expression:

@Inject
Event<String> event;

from("direct:event")
    .process(exchange -> event.fire(exchange.getIn().getBody(String.class)))
    .log("CDI event sent: ${body}");

@Inject
Event<String> event;

from("direct:event")
    .process(exchange -> event.fire(exchange.getIn().getBody(String.class)))
    .log("CDI event sent: ${body}");

Toggle word wrap

The type variable T (resp. the qualifiers) of a particular CdiEventEndpoint<T> injection point are automatically translated into the parameterized event type (resp. into the event qualifiers) e.g.:

@Inject
@FooQualifier
CdiEventEndpoint<List<String>> cdiEventEndpoint;

from("direct:event").to(cdiEventEndpoint);

void observeCdiEvents(@Observes @FooQualifier List<String> event) {
    logger.info("CDI event: {}", event);
}

@Inject
@FooQualifier
CdiEventEndpoint<List<String>> cdiEventEndpoint;

from("direct:event").to(cdiEventEndpoint);

void observeCdiEvents(@Observes @FooQualifier List<String> event) {
    logger.info("CDI event: {}", event);
}

Copy to Clipboard

Toggle word wrap

When multiple Camel contexts exist in the CDI container, the Camel context bean qualifiers, like @ContextName, can be used to qualify the CdiEventEndpoint<T> injection points, e.g.:

@Inject
@ContextName("foo")
CdiEventEndpoint<List<String>> cdiEventEndpoint;
// Only observes / consumes events having the @ContextName("foo") qualifier
from(cdiEventEndpoint).log("Camel context (foo) > CDI event received: ${body}");
// Produces / fires events with the @ContextName("foo") qualifier
from("...").to(cdiEventEndpoint);

void observeCdiEvents(@Observes @ContextName("foo") List<String> event) {
    logger.info("Camel context (foo) > CDI event: {}", event);
}

@Inject
@ContextName("foo")
CdiEventEndpoint<List<String>> cdiEventEndpoint;
// Only observes / consumes events having the @ContextName("foo") qualifier
from(cdiEventEndpoint).log("Camel context (foo) > CDI event received: ${body}");
// Produces / fires events with the @ContextName("foo") qualifier
from("...").to(cdiEventEndpoint);

void observeCdiEvents(@Observes @ContextName("foo") List<String> event) {
    logger.info("Camel context (foo) > CDI event: {}", event);
}

Copy to Clipboard

Note that the CDI event Camel endpoint dynamically adds an observer method for each unique combination of event type and event qualifiers and solely relies on the container typesafe observer resolution, which leads to an implementation as efficient as possible.

Besides, as the impedance between the typesafe nature of CDI and the dynamic nature of the Camel component model is quite high, it is not possible to create an instance of the CDI event Camel endpoint via URIs. Indeed, the URI format for the CDI event component is:

cdi-event://PayloadType<T1,...,Tn>[?qualifiers=QualifierType1[,...[,QualifierTypeN]...]]

cdi-event://PayloadType<T1,...,Tn>[?qualifiers=QualifierType1[,...[,QualifierTypeN]...]]

Copy to Clipboard

Toggle word wrap

With the authority PayloadType (resp. the QualifierType) being the URI escaped fully qualified name of the payload (resp. qualifier) raw type followed by the type parameters section delimited by angle brackets for payload parameterized type. Which leads to unfriendly URIs, e.g.:

cdi-event://org.apache.camel.cdi.example.EventPayload%3Cjava.lang.Integer%3E?qualifiers=org.apache.camel.cdi.example.FooQualifier%2Corg.apache.camel.cdi.example.BarQualifier

cdi-event://org.apache.camel.cdi.example.EventPayload%3Cjava.lang.Integer%3E?qualifiers=org.apache.camel.cdi.example.FooQualifier%2Corg.apache.camel.cdi.example.BarQualifier

But more fundamentally, that would prevent efficient binding between the endpoint instances and the observer methods as the CDI container doesn’t have any ways of discovering the Camel context model during the deployment phase.

59.11. Camel XML configuration import
复制链接

Available as of Camel 2.18

While CDI favors a typesafe dependency injection mechanism, it may be useful to reuse existing Camel XML configuration files into a Camel CDI application. In other use cases, it might be handy to rely on the Camel XML DSL to configure its Camel context(s).

You can use the @ImportResource annotation that’s provided by Camel CDI on any CDI beans and Camel CDI will automatically load the Camel XML configuration at the specified locations, e.g.:

@ImportResource("camel-context.xml")
class MyBean {
}

@ImportResource("camel-context.xml")
class MyBean {
}

Copy to Clipboard

Toggle word wrap

Camel CDI will load the resources at the specified locations from the classpath (other protocols may be added in the future).

Every CamelContext elements and other Camel primitives from the imported resources are automatically deployed as CDI beans during the container bootstrap so that they benefit from the auto-configuration provided by Camel CDI and become available for injection at runtime. If such an element has an explicit id attribute set, the corresponding CDI bean is qualified with the @Named qualifier, e.g., given the following Camel XML configuration:

<camelContext id="foo">
    <endpoint id="bar" uri="seda:inbound">
        <property key="queue" value="#queue"/>
        <property key="concurrentConsumers" value="10"/>
    </endpoint>
<camelContext/>

<camelContext id="foo">
    <endpoint id="bar" uri="seda:inbound">
        <property key="queue" value="#queue"/>
        <property key="concurrentConsumers" value="10"/>
    </endpoint>
<camelContext/>

Copy to Clipboard

Toggle word wrap

The corresponding CDI beans are automatically deployed and can be injected, e.g.:

@Inject
@ContextName("foo")
CamelContext context;

@Inject
@Named("bar")
Endpoint endpoint;

@Inject
@ContextName("foo")
CamelContext context;

@Inject
@Named("bar")
Endpoint endpoint;

Copy to Clipboard

Toggle word wrap

Note that the CamelContext beans are automatically qualified with both the @Named and @ContextName qualifiers. If the imported CamelContext element doesn’t have an id attribute, the corresponding bean is deployed with the built-in @Default qualifier.

Conversely, CDI beans deployed in the application can be referred to from the Camel XML configuration, usually using the ref attribute, e.g., given the following bean declared:

@Produces
@Named("baz")
Processor processor = exchange -> exchange.getIn().setHeader("qux", "quux");

@Produces
@Named("baz")
Processor processor = exchange -> exchange.getIn().setHeader("qux", "quux");

A reference to that bean can be declared in the imported Camel XML configuration, e.g.:

    </route>
<camelContext/>

<camelContext id="foo">

59.12. Transaction support
复制链接

Available as of Camel 2.19

Camel CDI provides support for Camel transactional client using JTA.

That support is optional hence you need to have JTA in your application classpath, e.g., by explicitly add JTA as a dependency when using Maven:

<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>javax.transaction-api</artifactId>
    <scope>runtime</scope>
</dependency>

<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>javax.transaction-api</artifactId>
    <scope>runtime</scope>
</dependency>

Copy to Clipboard

Toggle word wrap

You’ll have to have your application deployed in a JTA capable container or provide a standalone JTA implementation.

Important

Note that, for the time being, the transaction manager is looked up as JNDI resource with the java:/TransactionManager key.

More flexible strategies will be added in the future to support a wider range of deployment scenarios.

59.12.1. Transaction policies
复制链接

Camel CDI provides implementation for the typically supported Camel TransactedPolicy as CDI beans. It is possible to have these policies looked up by name using the transacted EIP, e.g.:

class MyRouteBean extends RouteBuilder {

    @Override
    public void configure() {
        from("activemq:queue:foo")
            .transacted("PROPAGATION_REQUIRED")
            .bean("transformer")
            .to("jpa:my.application.entity.Bar")
            .log("${body.id} inserted");
    }
}

class MyRouteBean extends RouteBuilder {

    @Override
    public void configure() {
        from("activemq:queue:foo")
            .transacted("PROPAGATION_REQUIRED")
            .bean("transformer")
            .to("jpa:my.application.entity.Bar")
            .log("${body.id} inserted");
    }
}

        from("activemq:queue:foo")
            .policy(required)
            .bean("transformer")
            .to("jpa:my.application.entity.Bar")
            .log("${body.id} inserted");
    }
}

class MyRouteBean extends RouteBuilder {

    @Inject
    @Named("PROPAGATION_REQUIRED")
    Policy required;

    @Override
    public void configure() {
        from("activemq:queue:foo")
            .policy(required)
            .bean("transformer")

59.12.2. Transactional error handler

Camel CDI provides a transactional error handler that extends the redelivery error handler, forces a rollback whenever an exception occurs and creates a new transaction for each redelivery.

Camel CDI provides the CdiRouteBuilder class that exposes the transactionErrorHandler helper method to enable quick access to the configuration, e.g.:

class MyRouteBean extends CdiRouteBuilder {

    @Override
    public void configure() {
        errorHandler(transactionErrorHandler()
            .setTransactionPolicy("PROPAGATION_SUPPORTS")
            .maximumRedeliveries(5)
            .maximumRedeliveryDelay(5000)
            .collisionAvoidancePercent(10)
            .backOffMultiplier(1.5));
    }
}

class MyRouteBean extends CdiRouteBuilder {

    @Override
    public void configure() {
        errorHandler(transactionErrorHandler()
            .setTransactionPolicy("PROPAGATION_SUPPORTS")
            .maximumRedeliveries(5)
            .maximumRedeliveryDelay(5000)

59.13. Auto-configured OSGi integration
复制链接

Available as of Camel 2.17

The Camel context beans are automatically adapted by Camel CDI so that they are registered as OSGi services and the various resolvers (like ComponentResolver and DataFormatResolver) integrate with the OSGi registry. That means that the Karaf Camel commands can be used to operate the Camel contexts auto-configured by Camel CDI, e.g.:

karaf@root()> camel:context-list
 Context        Status              Total #       Failed #     Inflight #   Uptime
 -------        ------              -------       --------     ----------   ------

59.14. Lazy Injection / Programmatic Lookup
复制链接

While the CDI programmatic model favors a typesafe resolution mechanism that occurs at application initialization time, it is possible to perform dynamic / lazy injection later during the application execution using the programmatic lookup mechanism.

Camel CDI provides for convenience the annotation literals corresponding to the CDI qualifiers that you can use for standard injection of Camel primitives. These annotation literals can be used in conjunction with the javax.enterprise.inject.Instance interface which is the CDI entry point to perform lazy injection / programmatic lookup.

For example, you can use the provided annotation literal for the @Uri qualifier to lazily lookup for Camel primitives, e.g. for ProducerTemplate beans:

@Any
@Inject
Instance<ProducerTemplate> producers;

ProducerTemplate inbound = producers
    .select(Uri.Literal.of("direct:inbound"))
    .get();

@Any
@Inject
Instance<ProducerTemplate> producers;

ProducerTemplate inbound = producers
    .select(Uri.Literal.of("direct:inbound"))
    .get();

Or for Endpoint beans, e.g.:

@Any
@Inject
Instance<Endpoint> endpoints;

MockEndpoint outbound = endpoints
    .select(MockEndpoint.class, Uri.Literal.of("mock:outbound"))
    .get();

@Any
@Inject
Instance<Endpoint> endpoints;

MockEndpoint outbound = endpoints
    .select(MockEndpoint.class, Uri.Literal.of("mock:outbound"))
    .get();

Copy to Clipboard

Toggle word wrap

Similarly, you can use the provided annotation literal for the @ContextName qualifier to lazily lookup for CamelContext beans, e.g.:

@Any
@Inject
Instance<CamelContext> contexts;

CamelContext context = contexts
    .select(ContextName.Literal.of("foo"))
    .get();

@Any
@Inject
Instance<CamelContext> contexts;

CamelContext context = contexts
    .select(ContextName.Literal.of("foo"))
    .get();

Copy to Clipboard

Toggle word wrap

You can also refined the selection based on the Camel context type, e.g.:

@Any
@Inject
Instance<CamelContext> contexts;

// Refine the selection by type
Instance<DefaultCamelContext> context = contexts.select(DefaultCamelContext.class);

// Check if such a bean exists then retrieve a reference
if (!context.isUnsatisfied())
    context.get();

@Any
@Inject
Instance<CamelContext> contexts;

// Refine the selection by type
Instance<DefaultCamelContext> context = contexts.select(DefaultCamelContext.class);

// Check if such a bean exists then retrieve a reference
if (!context.isUnsatisfied())
    context.get();

59.19. Camel CDI for EAR deployments on {wildfly-camel}
复制链接

Camel CDI EAR deployments on {wildfly-camel} have some differences in class and resource loading behaviour, compared to standard WAR or JAR deployments.

{wildfly} bootstraps Weld using the EAR deployment ClassLoader. {wildfly} also mandates that only a single CDI extension is created and shared by all EAR sub-deployments.

This results in the 'Auto-configured' CDI Camel Context using the EAR deployment ClassLoader to dynamically load classes and resources. By default, this ClassLoader does not have access to resources within EAR sub-deployments.

For EAR deployments, it is recommended that usage of the 'Auto-configured' CDI Camel Context is avoided and that RouteBuilder classes are annotated with @ContextName, or that a CamelContext is created via the @ImportResource annotation or through CDI producer methods and fields. This helps {wildfly-camel} to determine the correct ClassLoader to use with Camel.

You can prefix with: classpath, file, http, ref, or bean. classpath, file and http loads the resource using these protocols (classpath is default). ref will lookup the resource in the registry. bean will call a method on a bean to be used as the resource. For bean you can specify the method name after dot, eg bean:myBean.myMethod.		String

61.2.2. Query Parameters (7 parameters):
复制链接

Expand

Name	Description	Default	Type
contentCache (producer)	Sets whether to use resource content cache or not	false	boolean
encoding (producer)	Define the encoding of the body		String
extension (producer)	Define the file extension of the template		String
themeFolder (producer)	Define the themes folder to scan		String
themeLayer (producer)	Define the theme layer to elaborate		String
themeSubfolder (producer)	Define the themes subfolder to scan		String
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean

Chunk component will look for a specific template in themes folder with extensions .chtml or _.cxml. _If you need to specify a different folder or extensions, you will need to use the specific options listed above.

61.3. Chunk Context
复制链接

Camel will provide exchange information in the Chunk context (just a Map). The Exchange is transferred as:

Expand

key	value
`exchange`	The `Exchange` itself.
`exchange.properties`	The `Exchange` properties.
`headers`	The headers of the In message.
`camelContext`	The Camel Context.
`request`	The In message.
`body`	The In message body.
`response`	The Out message (only for InOut message exchange pattern).

61.4. Dynamic templates
复制链接

Camel provides two headers by which you can define a different resource location for a template or the template content itself. If any of these headers is set then Camel uses this over the endpoint configured resource. This allows you to provide a dynamic template at runtime.

Expand

Header	Type	Description	Support Version
ChunkConstants.CHUNK_RESOURCE_URI	String	A URI for the template resource to use instead of the endpoint configured.
ChunkConstants.CHUNK_TEMPLATE	String	The template to use instead of the endpoint configured.

61.5. Samples
复制链接

For example you could use something like:

from("activemq:My.Queue").
to("chunk:template");

from("activemq:My.Queue").
to("chunk:template");

Copy to Clipboard

Toggle word wrap

To use a Chunk template to formulate a response for a message for InOut message exchanges (where there is a JMSReplyTo header).

If you want to use InOnly and consume the message and send it to another destination you could use:

from("activemq:My.Queue").
to("chunk:template").
to("activemq:Another.Queue");

from("activemq:My.Queue").
to("chunk:template").
to("activemq:Another.Queue");

Copy to Clipboard

Toggle word wrap

It’s possible to specify what template the component should use dynamically via a header, so for example:

from("direct:in").
setHeader(ChunkConstants.CHUNK_RESOURCE_URI).constant("template").
to("chunk:dummy");

from("direct:in").
setHeader(ChunkConstants.CHUNK_RESOURCE_URI).constant("template").
to("chunk:dummy");

Copy to Clipboard

Toggle word wrap

An example of Chunk component options use:

from("direct:in").
to("chunk:file_example?themeFolder=template&themeSubfolder=subfolder&extension=chunk");

from("direct:in").
to("chunk:file_example?themeFolder=template&themeSubfolder=subfolder&extension=chunk");

Copy to Clipboard

Toggle word wrap

In this example Chunk component will look for the file file_example.chunk in the folder template/subfolder.

61.6. The Email Sample
复制链接

In this sample we want to use Chunk templating for an order confirmation email. The email template is laid out in Chunk as:

 
Dear {$headers.lastName}, {$headers.firstName}

Thanks for the order of {$headers.item}.

Regards Camel Riders Bookstore
{$body}

 
Dear {$headers.lastName}, {$headers.firstName}

multiParameterArray (advanced)	Deprecated How to treat the parameters which are passed from the message body; if it is true, the message body should be an array of parameters. Note: This option is used internally by Camel, and is not intended for end users to use. Deprecation note: This option is used internally by Camel, and is not intended for end users to use.	false	boolean
parameters (advanced)	Used for configuring additional properties on the bean		Map
synchronous (advanced)	Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).	false	boolean

62.3. Using
复制链接

You simply use the class component just as the Bean component but by specifying the fully qualified classname instead.
For example to use the MyFooBean you have to do as follows:

    from("direct:start").to("class:org.apache.camel.component.bean.MyFooBean").to("mock:result");

    from("direct:start").to("class:org.apache.camel.component.bean.MyFooBean").to("mock:result");

Copy to Clipboard

Toggle word wrap

You can also specify which method to invoke on the MyFooBean, for example hello:

    from("direct:start").to("class:org.apache.camel.component.bean.MyFooBean?method=hello").to("mock:result");

    from("direct:start").to("class:org.apache.camel.component.bean.MyFooBean?method=hello").to("mock:result");

Copy to Clipboard

62.4. Setting properties on the created instance
复制链接

In the endpoint uri you can specify properties to set on the created instance, for example if it has a setPrefix method:

   // Camel 2.17 onwards
   from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?bean.prefix=Bye")
        .to("mock:result");
 
   // Camel 2.16 and older 
   from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?prefix=Bye")
        .to("mock:result");

   // Camel 2.17 onwards
   from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?bean.prefix=Bye")
        .to("mock:result");
 
   // Camel 2.16 and older 
   from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?prefix=Bye")
        .to("mock:result");

Copy to Clipboard

Toggle word wrap

And you can also use the # syntax to refer to properties to be looked up in the Registry.

    // Camel 2.17 onwards
    from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?bean.cool=#foo")
        .to("mock:result");

    // Camel 2.16 and older
    from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?cool=#foo")
        .to("mock:result");

    // Camel 2.17 onwards
    from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?bean.cool=#foo")
        .to("mock:result");

    // Camel 2.16 and older
    from("direct:start")
        .to("class:org.apache.camel.component.bean.MyPrefixBean?cool=#foo")
        .to("mock:result");

Copy to Clipboard

Toggle word wrap

Which will lookup a bean from the Registry with the id foo and invoke the setCool method on the created instance of the MyPrefixBean class.
