Chapter 12. Azure ServiceBus
Since Camel 3.12
Both producer and consumer are supported
The azure-servicebus component that integrates Azure ServiceBus. Azure ServiceBus is a fully managed enterprise integration message broker. Service Bus can decouple applications and services. Service Bus offers a reliable and secure platform for asynchronous transfer of data and state. Data is transferred between different applications and services using messages.
Prerequisites
You must have a valid Windows Azure Storage account. More information is available at Azure Documentation Portal.
12.1. Dependencies
When using azure-servicebus with Red Hat build of Camel Spring Boot, add the following Maven dependency to your pom.xml to have support for auto configuration:
<dependency> <groupId>org.apache.camel.springboot</groupId> <artifactId>camel-azure-servicebus-starter</artifactId> </dependency>
12.2. Configuring Options
Camel components are configured on two levels:
- Component level
- Endpoint level
12.2.1. Component Level Options
The component level is the highest level. The configurations you define at this level are inherited by all the endpoints. For example, a component can have security settings, credentials for authentication, urls for network connection, and so on.
Since components typically have pre-configured defaults for the most common cases, you may need to only configure a few component options, or maybe none at all.
You can configure components with Component DSL in a configuration file (application.properties|yaml), or directly with Java code.
12.2.2. Endpoint Level Options
At the Endpoint level you have many options, which you can use to configure what you want the endpoint to do. The options are categorized according to whether the endpoint is used as a consumer (from) or as a producer (to) or used for both.
You can configure endpoints directly in the endpoint URI as path and query parameters. You can also use Endpoint DSL and DataFormat DSL as type safe ways of configuring endpoints and data formats in Java.
When configuring options, use Property Placeholders for urls, port numbers, sensitive information, and other settings.
Placeholders allows you to externalize the configuration from your code, giving you more flexible and reusable code.
12.3. Component Options
The Azure ServiceBus component supports 25 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
| amqpRetryOptions (common) | Sets the retry options for Service Bus clients. If not specified, the default retry options are used. | AmqpRetryOptions | |
| amqpTransportType (common) | Sets the transport type by which all the communication with Azure Service Bus occurs. Default value is AmqpTransportType#AMQP. Enum values:
| AMQP | AmqpTransportType |
| clientOptions (common) | Sets the ClientOptions to be sent from the client built from this builder, enabling customization of certain properties, as well as support the addition of custom header information. Refer to the ClientOptions documentation for more information. | ClientOptions | |
| configuration (common) | The component configurations. | ServiceBusConfiguration | |
| proxyOptions (common) | Sets the proxy configuration to use for ServiceBusSenderAsyncClient. When a proxy is configured, AmqpTransportType#AMQP_WEB_SOCKETS must be used for the transport type. | ProxyOptions | |
| serviceBusType (common) | Required The service bus type of connection to execute. Queue is for typical queue option and topic for subscription based model. Enum values:
| queue | ServiceBusType |
| 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 |
| consumerOperation (consumer) | Sets the desired operation to be used in the consumer. Enum values:
| receiveMessages | ServiceBusConsumerOperationDefinition |
| disableAutoComplete (consumer) | Disables auto-complete and auto-abandon of received messages. By default, a successfully processed message is \\{link ServiceBusReceiverAsyncClient#complete(ServiceBusReceivedMessage) completed}. If an error happens when the message is processed, it is \\{link ServiceBusReceiverAsyncClient#abandon(ServiceBusReceivedMessage) abandoned}. | false | boolean |
| maxAutoLockRenewDuration (consumer) | Sets the amount of time to continue auto-renewing the lock. Setting Duration#ZERO or null disables auto-renewal. For \\{link ServiceBusReceiveMode#RECEIVE_AND_DELETE RECEIVE_AND_DELETE} mode, auto-renewal is disabled. | 5m | Duration |
| peekNumMaxMessages (consumer) | Set the max number of messages to be peeked during the peek operation. | Integer | |
| prefetchCount (consumer) | Sets the prefetch count of the receiver. For both \\{link ServiceBusReceiveMode#PEEK_LOCK PEEK_LOCK} and \\{link ServiceBusReceiveMode#RECEIVE_AND_DELETE RECEIVE_AND_DELETE} modes the default value is 1. Prefetch speeds up the message flow by aiming to have a message readily available for local retrieval when and before the application asks for one using ServiceBusReceiverAsyncClient#receiveMessages(). Setting a non-zero value will prefetch that number of messages. Setting the value to zero turns prefetch off. | int | |
| receiverAsyncClient (consumer) | Autowired Sets the receiverAsyncClient in order to consume messages by the consumer. | ServiceBusReceiverAsyncClient | |
| serviceBusReceiveMode (consumer) | Sets the receive mode for the receiver. Enum values:
| PEEK_LOCK | ServiceBusReceiveMode |
| subQueue (consumer) | Sets the type of the SubQueue to connect to. Enum values:
| SubQueue | |
| subscriptionName (consumer) | Sets the name of the subscription in the topic to listen to. topicOrQueueName and serviceBusType=topic must also be set. This property is required if serviceBusType=topic and the consumer is in use. | String | |
| lazyStartProducer (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean |
| producerOperation (producer) | Sets the desired operation to be used in the producer. Enum values:
| sendMessages | ServiceBusProducerOperationDefinition |
| scheduledEnqueueTime (producer) | Sets OffsetDateTime at which the message should appear in the Service Bus queue or topic. | OffsetDateTime | |
| senderAsyncClient (producer) | Autowired Sets SenderAsyncClient to be used in the producer. | ServiceBusSenderAsyncClient | |
| serviceBusTransactionContext (producer) | Represents transaction in service. This object just contains transaction id. | ServiceBusTransactionContext | |
| autowiredEnabled (advanced) | Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. | true | boolean |
| connectionString (security) | Sets the connection string for a Service Bus namespace or a specific Service Bus resource. | String | |
| fullyQualifiedNamespace (security) | Fully Qualified Namespace of the service bus. | String | |
| tokenCredential (security) | A TokenCredential for Azure AD authentication, implemented in com.azure.identity. | TokenCredential |
