2.2.3. Additional Camel Quarkus configuration

Beyond standard usages known from vanilla Camel, Camel Quarkus adds the possibility to parse the Avro schema at build time both in JVM and Native mode.

The approach to generate Avro classes from Avro schema files is the one coined by the quarkus-avro extension. It requires the following:

Store *.avsc files in a folder named src/main/avro or src/test/avro

In addition to the usual build goal of quarkus-maven-plugin, add the generate-code goal:

<plugin>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>generate-code-and-build</id>
            <goals>
                <goal>generate-code</goal>
                <goal>build</goal>

2.4.3. SSL in native mode

This extension auto-enables SSL support in native mode. Hence you do not need to add quarkus.ssl.native=true to your application.properties yourself. See also Quarkus SSL guide.

2.4.4. Additional Camel Quarkus configuration

2.4.4.1. Optional integration with Quarkus Amazon DynamoDB

If desired, it is possible to use the Quarkus Amazon DynamoDB extension in conjunction with Camel Quarkus AWS 2 DynamoDB. Note that this is fully optional and not mandatory at all. Please follow the Quarkus documentation but beware of the following caveats:

The client type apache has to be selected by configuring the following property:
```
quarkus.dynamodb.sync-client.type=apache
```

The DynamoDbClient has to be made "unremovable" in the sense of Quarkus CDI reference so that Camel Quarkus is able to look it up at runtime. You can reach that e.g. by adding a dummy bean injecting DynamoDbClient:

import javax.enterprise.context.ApplicationScoped;
import io.quarkus.arc.Unremovable;
import software.amazon.awssdk.services.dynamodb.DynamoDbClient;

@ApplicationScoped
@Unremovable
class UnremovableDynamoDbClient {

If desired, it is possible to use the Quarkus Amazon S3 extension in conjunction with Camel Quarkus AWS 2 S3 Storage Service. Note that this is fully optional and not mandatory at all. Please follow the Quarkus documentation but beware of the following caveats:

The client type apache has to be selected by configuring the following property:
```
quarkus.s3.sync-client.type=apache
```

The S3Client has to be made "unremovable" in the sense of Quarkus CDI reference so that Camel Quarkus is able to look it up at runtime. You can reach that e.g. by adding a dummy bean injecting S3Client:

import javax.enterprise.context.ApplicationScoped;
import io.quarkus.arc.Unremovable;
import software.amazon.awssdk.services.s3.S3Client;

@ApplicationScoped
@Unremovable

The client type apache has to be selected by configuring the following property:
```
quarkus.sqs.sync-client.type=apache
```

The SqsClient has to be made "unremovable" in the sense of Quarkus CDI reference so that Camel Quarkus is able to look it up at runtime. You can reach that e.g. by adding a dummy bean injecting SqsClient:

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-bean-validator</artifactId>
</dependency>

2.12.3. Usage

2.12.3.1. Configuring the ValidatorFactory

Implementation of this extension leverages the Quarkus Hibernate Validator extension.

Therefore it is not possible to configure the ValidatorFactory by Camel’s properties (constraintValidatorFactory, messageInterpolator, traversableResolver, validationProviderResolver and validatorFactory).

You can configure the ValidatorFactory by the creation of beans which will be injected into the default ValidatorFactory (created by Quarkus). See the Quarkus CDI documentation for more information.

2.12.3.2. Custom validation groups in native mode

When using custom validation groups in native mode, all the interfaces need to be registered for reflection (see the documentation).

Example:

@RegisterForReflection
public interface OptionalChecks {
}

2.12.4. Camel Quarkus limitations

It is not possible to describe your constraints as XML (by providing the file META-INF/validation.xml), only Java annotations are supported. This is caused by the limitation of the Quarkus Hibernate Validator extension (see the issue).

2.13. Bean

Invoke methods of Java beans

2.13.1. What’s inside

Bean component, URI syntax: bean:beanName
Bean Method language
Class component, URI syntax: class:beanName

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-bean</artifactId>
</dependency>

2.13.3. Usage

Except for invoking methods of beans available in Camel registry, Bean component and Bean method language can also invoke Quarkus CDI beans.

2.14. Bindy

Marshal and unmarshal between POJOs on one side and Comma separated values (CSV), fixed field length or key-value pair (KVP) formats on the other side using Camel Bindy

2.14.1. What’s inside

Please refer to the above links for usage and configuration details.

2.14.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

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

2.14.3. Camel Quarkus limitations

When using camel-quarkus-bindy in native mode, only the build machine’s locale is supported.

For instance, on build machines with french locale, the code below:

BindyDataFormat dataFormat = new BindyDataFormat();
dataFormat.setLocale("ar");

formats numbers the arabic way in JVM mode as expected. However, it formats numbers the french way in native mode.

Without further tuning, the build machine’s default locale would be used. Another locale could be specified with the quarkus.native.user-language and quarkus.native.user-country configuration properties.

2.15. Browse

Inspect the messages received on endpoints supporting BrowsableEndpoint.

2.15.1. What’s inside

</dependency>

2.16.3. Additional Camel Quarkus configuration

2.16.3.1. Cassandra aggregation repository in native mode

In order to use Cassandra aggregation repositories like CassandraAggregationRepository in native mode, you must enable native serialization support.

In addition, if your exchange bodies are custom types, then they must be registered for serialization by annotating their class declaration with @RegisterForReflection(serialization = true).

2.17. Control Bus

Manage and monitor Camel routes.

2.17.1. What’s inside

Control Bus component, URI syntax: controlbus:command:language

Please refer to the above link for usage and configuration details.

2.17.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-controlbus</artifactId>
</dependency>

2.17.3. Usage

2.17.3.1. Languages

The following languages are supported for use in the Control Bus extension in Camel Extensions for Quarkus:

2.17.3.1.1. Bean

The Bean language can be used to invoke a method on a bean to control the state of routes. The org.apache.camel.quarkus:camel-quarkus-bean extension must be added to the classpath. Maven users must add the following dependency to the POM:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-bean</artifactId>
</dependency>

In native mode, the bean class must be annotated with @RegisterForReflection.

2.17.3.1.2. Simple

The Simple language can be used to control the state of routes. The following example uses a ProducerTemplate to stop a route with the id foo:

template.sendBody(
    "controlbus:language:simple",
    "${camelContext.getRouteController().stopRoute('foo')}"
);

To use the OGNL notation, the org.apache.camel.quarkus:camel-quarkus-bean extension must be added as a dependency.

In native mode, the classes used in the OGNL notation must be registered for reflection. In the above code snippet, the org.apache.camel.spi.RouteController class returned from camelContext.getRouteController() must be registered. As this is a third-party class, it cannot be annotated with @RegisterForReflection directly - instead you can annotate a different class and specifying the target classes to register. For example, the class defining the Camel routes could be annotated with @RegisterForReflection(targets = { org.apache.camel.spi.RouteController.class }).

Alternatively, add the following line to your src/main/resources/application.properties:

quarkus.camel.native.reflection.include-patterns = org.apache.camel.spi.RouteController

2.17.4. Camel Quarkus limitations

2.17.4.1. Statistics

This feature is not supported in Camel Extensions for Quarkus.

2.18. Core

Camel core functionality and basic Camel languages/ Constant, ExchangeProperty, Header, Ref, Simple and Tokenize

2.18.1. What’s inside

Please refer to the above links for usage and configuration details.

2.18.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-core</artifactId>
</dependency>

2.18.3. Additional Camel Quarkus configuration

2.18.3.1. Simple language

2.18.3.1.1. Using the OGNL notation

When using the OGNL notation from the simple language, the camel-quarkus-bean extension should be used.

For instance, the simple expression below is accessing the getAddress() method on the message body of type Client.

---
simple("${body.address}")
---

In such a situation, one should take an additional dependency on the camel-quarkus-bean extension as described here. Note that in native mode, some classes may need to be registered for reflection. In the example above, the Client class needs to be registered for reflection.

2.18.3.1.2. Using dynamic type resolution in native mode

When dynamically resolving a type from simple expressions like:

simple("${mandatoryBodyAs(TYPE)}")
simple("${type:package.Enum.CONSTANT}")
from("…").split(bodyAs(TYPE.class))
simple("${body} is TYPE")

It may be needed to register some classes for reflection manually.

For instance, the simple expression below is dynamically resolving the type java.nio.ByteBuffer at runtime:

---
simple("${body} is 'java.nio.ByteBuffer'")
---

As such, the class java.nio.ByteBuffer needs to be registered for reflection.

2.18.3.1.3. Using the simple language with classpath resources in native mode

If your route is supposed to load a Simple script from classpath, like in the following example

from("direct:start").transform().simple("resource:classpath:mysimple.txt");

then you need to use Quarkus quarkus.native.resources.includes property to include the resource in the native executable as demonstrated below:

quarkus.native.resources.includes = mysimple.txt

2.18.3.1.4. Configuring a custom bean via properties in native mode

When specifying a custom bean via properties in native mode with configuration like #class:* or #type:*, it may be needed to register some classes for reflection manually.

For instance, the custom bean definition below involves the use of reflection for bean instantiation and setter invocation:

---
camel.beans.customBeanWithSetterInjection = #class:org.example.PropertiesCustomBeanWithSetterInjection
camel.beans.customBeanWithSetterInjection.counter = 123
---

As such, the class PropertiesCustomBeanWithSetterInjection needs to be registered for reflection, note that field access could be omitted in this case.

Configuration property	Type	Default
`quarkus.camel.bootstrap.enabled` When set to true, the `CamelRuntime` will be started automatically.	`boolean`	`true`
`quarkus.camel.service.discovery.exclude-patterns` A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will not be discoverable via the `org.apache.camel.spi.FactoryFinder` mechanism. The excludes have higher precedence than includes. The excludes defined here can also be used to veto the discoverability of services included by Camel Quarkus extensions. Example values: `META-INF/services/org/apache/camel/foo/,META-INF/services/org/apache/camel/foo/*/bar`	`string`
`quarkus.camel.service.discovery.include-patterns` A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will be discoverable via the `org.apache.camel.spi.FactoryFinder` mechanism unless the given file is excluded via `exclude-patterns`. Note that Camel Quarkus extensions may include some services by default. The services selected here added to those services and the exclusions defined in `exclude-patterns` are applied to the union set. Example values: `META-INF/services/org/apache/camel/foo/,META-INF/services/org/apache/camel/foo/*/bar`	`string`
`quarkus.camel.service.registry.exclude-patterns` A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will not be added to Camel registry during application’s static initialization. The excludes have higher precedence than includes. The excludes defined here can also be used to veto the registration of services included by Camel Quarkus extensions. Example values: `META-INF/services/org/apache/camel/foo/,META-INF/services/org/apache/camel/foo/*/bar`	`string`
`quarkus.camel.service.registry.include-patterns` A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will be added to Camel registry during application’s static initialization unless the given file is excluded via `exclude-patterns`. Note that Camel Quarkus extensions may include some services by default. The services selected here added to those services and the exclusions defined in `exclude-patterns` are applied to the union set. Example values: `META-INF/services/org/apache/camel/foo/,META-INF/services/org/apache/camel/foo/*/bar`	`string`
`quarkus.camel.runtime-catalog.components` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel components available in the application; otherwise component JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.runtime-catalog.languages` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel languages available in the application; otherwise language JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.runtime-catalog.dataformats` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel data formats available in the application; otherwise data format JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.runtime-catalog-models` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel EIP models available in the application; otherwise EIP model JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.routes-discovery.enabled` Enable automatic discovery of routes during static initialization.	`boolean`	`true`
`quarkus.camel.routes-discovery.exclude-patterns` Used for exclusive filtering scanning of RouteBuilder classes. The exclusive filtering takes precedence over inclusive filtering. The pattern is using Ant-path style pattern. Multiple patterns can be specified separated by comma. For example to exclude all classes starting with Bar use: */Bar To exclude all routes form a specific package use: com/mycompany/bar/* To exclude all routes form a specific package and its sub-packages use double wildcards: com/mycompany/bar/** And to exclude all routes from two specific packages use: com/mycompany/bar/,com/mycompany/stuff/	`string`
`quarkus.camel.routes-discovery.include-patterns` Used for inclusive filtering scanning of RouteBuilder classes. The exclusive filtering takes precedence over inclusive filtering. The pattern is using Ant-path style pattern. Multiple patterns can be specified separated by comma. For example to include all classes starting with Foo use: */Foo To include all routes form a specific package use: com/mycompany/foo/* To include all routes form a specific package and its sub-packages use double wildcards: com/mycompany/foo/** And to include all routes from two specific packages use: com/mycompany/foo/,com/mycompany/stuff/	`string`
`quarkus.camel.native.resources.exclude-patterns` Replaced by `quarkus.native.resources.excludes` in Camel Quarkus 2.0.0. Using this property throws an exception at build time.	`string`
`quarkus.camel.native.resources.include-patterns` Replaced by `quarkus.native.resources.includes` in Camel Quarkus 2.0.0. Using this property throws an exception at build time.	`string`
`quarkus.camel.native.reflection.exclude-patterns` A comma separated list of Ant-path style patterns to match class names that should be excluded from registering for reflection. Use the class name format as returned by the `java.lang.Class.getName()` method: package segments delimited by period `.` and inner classes by dollar sign `$`. This option narrows down the set selected by `include-patterns`. By default, no classes are excluded. This option cannot be used to unregister classes which have been registered internally by Quarkus extensions.	`string`
`quarkus.camel.native.reflection.include-patterns` A comma separated list of Ant-path style patterns to match class names that should be registered for reflection. Use the class name format as returned by the `java.lang.Class.getName()` method: package segments delimited by period `.` and inner classes by dollar sign `$`. By default, no classes are included. The set selected by this option can be narrowed down by `exclude-patterns`. Note that Quarkus extensions typically register the required classes for reflection by themselves. This option is useful in situations when the built in functionality is not sufficient. Note that this option enables the full reflective access for constructors, fields and methods. If you need a finer grained control, consider using `io.quarkus.runtime.annotations.RegisterForReflection` annotation in your Java code. For this option to work properly, at least one of the following conditions must be satisfied: - There are no wildcards (`` or `/`) in the patterns - The artifacts containing the selected classes contain a Jandex index (`META-INF/jandex.idx`) - The artifacts containing the selected classes are registered for indexing using the `quarkus.index-dependency.` family of options in `application.properties` - e.g. quarkus.index-dependency.my-dep.group-id = org.my-group quarkus.index-dependency.my-dep.artifact-id = my-artifact where `my-dep` is a label of your choice to tell Quarkus that `org.my-group` and with `my-artifact` belong together.	`string`
`quarkus.camel.native.reflection.serialization-enabled` If `true`, basic classes are registered for serialization; otherwise basic classes won’t be registered automatically for serialization in native mode. The list of classes automatically registered for serialization can be found in CamelSerializationProcessor.BASE_SERIALIZATION_CLASSES. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `true` except for making the behavior consistent with native mode.	`boolean`	`false`
`quarkus.camel.csimple.on-build-time-analysis-failure` What to do if it is not possible to extract CSimple expressions from a route definition at build time.	`org.apache.camel.quarkus.core.CamelConfig.FailureRemedy`	`warn`
`quarkus.camel.event-bridge.enabled` Whether to enable the bridging of Camel events to CDI events. This allows CDI observers to be configured for Camel events. E.g. those belonging to the `org.apache.camel.quarkus.core.events`, `org.apache.camel.quarkus.main.events` & `org.apache.camel.impl.event` packages. Note that this configuration item only has any effect when observers configured for Camel events are present in the application.	`boolean`	`true`
`quarkus.camel.source-location-enabled` Build time configuration options for enable/disable camel source location	`boolean`	`false`
`quarkus.camel.main.shutdown.timeout` A timeout (with millisecond precision) to wait for `CamelMain#stop()` to finish	`java.time.Duration`	`PT3S`
`quarkus.camel.main.arguments.on-unknown` The action to take when `CamelMain` encounters an unknown argument. fail - Prints the `CamelMain` usage statement and throws a `RuntimeException` ignore - Suppresses any warnings and the application startup proceeds as normal warn - Prints the `CamelMain` usage statement but allows the application startup to proceed as normal	`org.apache.camel.quarkus.core.CamelConfig.FailureRemedy`	`warn`

</dependency>

2.25.3. Additional Camel Quarkus configuration

2.25.3.1. Having only a single consumer in a cluster consuming from a given endpoint

When the same route is deployed on multiple JVMs, it could be interesting to use this extension in conjunction with the Master one. In such a setup, a single consumer will be active at a time across the whole camel master namespace.

For instance, having the route below deployed on multiple JVMs:

from("master:ns:timer:test?period=100").log("Timer invoked on a single JVM at a time");

It’s possible to enable the file cluster service with a property like below:

quarkus.camel.cluster.file.enabled = true
quarkus.camel.cluster.file-root = target/cluster-folder-where-lock-file-will-be-held

As a result, a single consumer will be active across the ns camel master namespace. It means that, at a given time, only a single timer will generate exchanges across all JVMs. In other words, messages will be logged every 100ms on a single JVM at a time.

The file cluster service could further be tuned by tweaking quarkus.camel.cluster.file.* properties.

Configuration property	Type	Default
`quarkus.camel.cluster.file.enabled` Whether a File Lock Cluster Service should be automatically configured according to 'quarkus.camel.cluster.file.*' configurations.	`boolean`	`false`
`quarkus.camel.cluster.file-id` The cluster service ID (defaults to null).	`string`
`quarkus.camel.cluster.file-root` The root path (defaults to null).	`string`
`quarkus.camel.cluster.file-order` The service lookup order/priority (defaults to 2147482647).	`java.lang.Integer`
`quarkus.camel.cluster.file.acquire-lock-delay` The time to wait before starting to try to acquire lock (defaults to 1000ms).	`string`
`quarkus.camel.cluster.file.acquire-lock-interval` The time to wait between attempts to try to acquire lock (defaults to 10000ms).	`string`
`quarkus.camel.cluster.file.attributes` The custom attributes associated to the service (defaults to empty map).	`Map<String,String>`

2.27.3. Additional Camel Quarkus configuration

2.27.3.1. Marshaling/Unmarshaling objects in native mode

When marshaling/unmarshaling objects in native mode, all the serialized classes need to be registered for reflection. As such, when using GsonDataFormat.setUnmarshalType(…), GsonDataFormat.setUnmarshalTypeName(…) and even GsonDataFormat.setUnmarshalGenericType(…), the unmarshal type as well as sub field types should be registered for reflection. See a working example in this integration test.

2.29.3. Camel Quarkus limitations

By default, the Camel PubSub component uses JDK object serialization via ObjectOutputStream whenever the message body is anything other than String or byte[].

Since such serialization is not yet supported by GraalVM, this extension provides a custom Jackson based serializer to serialize complex message payloads as JSON.

If your payload contains binary data, then you will need to handle that by creating a custom Jackson Serializer / Deserializer. Refer to the Quarkus Jackson guide for information on how to do this.

2.33.3. Usage

2.33.3.1. Configuring the Jackson `ObjectMapper`

There are a few ways of configuring the ObjectMapper that the JacksonDataFormat uses. These are outlined below.

2.33.3.1.1. `ObjectMapper` created internally by `JacksonDataFormat`

By default, JacksonDataFormat will create its own ObjectMapper and use the various configuration options on the DataFormat to configure additional Jackson modules, pretty printing and other features.

2.33.3.1.2. Custom `ObjectMapper` for `JacksonDataFormat`

You can pass a custom ObjectMapper instance to JacksonDataFormat as follows.

import com.fasterxml.jackson.databind.ObjectMapper;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.jackson.JacksonDataFormat;

public class Routes extends RouteBuilder {
    public void configure() {
        ObjectMapper mapper = new ObjectMapper();
        JacksonDataFormat dataFormat = new JacksonDataFormat();
        dataFormat.setObjectMapper(mapper);
        // Use the dataFormat instance in a route definition
        from("direct:my-direct").marshal(dataFormat)
    }
}

2.33.3.1.3. Using the Quarkus Jackson `ObjectMapper` with `JacksonDataFormat`

The Quarkus Jackson extension exposes an ObjectMapper CDI bean which can be discovered by the JacksonDataFormat.

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.jackson.JacksonDataFormat;

public class Routes extends RouteBuilder {
    public void configure() {
        JacksonDataFormat dataFormat = new JacksonDataFormat();
        // Make JacksonDataFormat discover the Quarkus Jackson `ObjectMapper` from the Camel registry
        dataFormat.setAutoDiscoverObjectMapper(true);
        // Use the dataFormat instance in a route definition
        from("direct:my-direct").marshal(dataFormat)
    }
}

If you are using the JSON binding mode in the Camel REST DSL and want to use the Quarkus Jackson ObjectMapper, it can be achieved as follows.

import org.apache.camel.builder.RouteBuilder;

@ApplicationScoped
public class Routes extends RouteBuilder {
    public void configure() {
        restConfiguration().dataFormatProperty("autoDiscoverObjectMapper", "true");
        // REST definition follows...
    }
}

You can perform customizations on the Quarkus ObjectMapper with a ObjectMapperCustomizer.

import com.fasterxml.jackson.databind.ObjectMapper;
import io.quarkus.jackson.ObjectMapperCustomizer;

@Singleton
public class RegisterCustomModuleCustomizer implements ObjectMapperCustomizer {
    public void customize(ObjectMapper mapper) {
        mapper.registerModule(new CustomModule());
    }
}

It’s also possible to @Inject the Quarkus ObjectMapper and pass it to the JacksonDataFormat.

import com.fasterxml.jackson.databind.ObjectMapper;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.jackson.JacksonDataFormat;

@ApplicationScoped
public class Routes extends RouteBuilder {
    @Inject
    ObjectMapper mapper;

    public void configure() {
        JacksonDataFormat dataFormat = new JacksonDataFormat();
        dataFormat.setObjectMapper(mapper);
        // Use the dataFormat instance in a route definition
        from("direct:my-direct").marshal(dataFormat)
    }
}

    <artifactId>camel-quarkus-jaxb</artifactId>
</dependency>

2.35.3. Usage

2.35.3.1. Native mode `ObjectFactory` instantiation of non-JAXB annotated classes

When performing JAXB marshal operations with a custom ObjectFactory to instantiate POJO classes that do not have JAXB annotations, you must register those POJO classes for reflection in order for them to be instantiated in native mode. E.g via the @RegisterForReflection annotation or configuration property quarkus.camel.native.reflection.include-patterns.

Refer to the Native mode user guide for more information.

2.36. Jira

    <artifactId>camel-quarkus-jms</artifactId>
</dependency>

2.37.3. Usage

2.37.3.1. Message mapping with `org.w3c.dom.Node`

The Camel JMS component supports message mapping between javax.jms.Message and org.apache.camel.Message. When wanting to convert a Camel message body type of org.w3c.dom.Node, you must ensure that the camel-quarkus-jaxp extension is present on the classpath.

2.37.3.2. Native mode support for javax.jms.ObjectMessage

When sending JMS message payloads as javax.jms.ObjectMessage, you must annotate the relevant classes to be registered for serialization with @RegisterForReflection(serialization = true).

Note

This extension automatically sets quarkus.camel.native.reflection.serialization-enabled = true for you. Refer to the native mode user guide for more information.

2.37.3.3. Support for Connection pooling and X/Open XA distributed transactions

Note

Connection pooling is a Technical Preview feature in this release of Camel Extensions for Quarkus.

To use connection pooling in the camel-quarkus-jms components, you must add io.quarkiverse.artemis:quarkus-artemis-jms and io.quarkiverse.messaginghub:quarkus-pooled-jms to your pom.xml and set the following configuration:

quarkus.pooled-jms.max-connections = 8

You can use the quarkus-pooled-jms extension to get pooling and XA support for JMS connections. Refer to the quarkus-pooled-jms extension documentation for more information. Currently, it only works with quarkus-artemis-jms extension. Just add these two dependencies to your pom.xml:

<dependency>
    <groupId>io.quarkiverse.messaginghub</groupId>
    <artifactId>quarkus-pooled-jms</artifactId>
</dependency>
<dependency>
    <groupId>io.quarkiverse.artemis</groupId>
    <artifactId>quarkus-artemis-jms</artifactId>
    <version>2.0.1</version>
</dependency>

Note

Pooling is enabled by default.

To enable XA, you need to add the following configuration to your application.properties:

quarkus.pooled-jms.xa.enabled=true

Note

clientID and durableSubscriptionName are not supported in pooling connections. If setClientID is called on a reused connection from the pool, an IllegalStateException will be thrown. You will get some error messages such like Cause: setClientID can only be called directly after the connection is created

2.37.4. transferException option in native mode

To use the transferException option in native mode, you must enable support for object serialization. Refer to the native mode user guide for more information.

You will also need to enable serialization for the exception classes that you intend to serialize. For example.

@RegisterForReflection(targets = { IllegalStateException.class, MyCustomException.class }, serialization = true)

2.38. JPA

Store and retrieve Java objects from databases using Java Persistence API (JPA).

2.41.1. What’s inside

JSLT component, URI syntax: jslt:resourceUri

Please refer to the above link for usage and configuration details.

2.41.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-jslt</artifactId>
</dependency>

2.41.3. allowContextMapAll option in native mode

The allowContextMapAll option is not supported in native mode as it requires reflective access to security sensitive camel core classes such as CamelContext & Exchange. This is considered a security risk and thus access to the feature is not provided by default.

2.41.4. Additional Camel Quarkus configuration

2.41.4.1. Loading JSLT templates from classpath in native mode

This component typically loads the templates from classpath. To make it work also in native mode, you need to explicitly embed the templates files in the native executable by using the quarkus.native.resources.includes property.

For instance, the route below would load the JSLT schema from a classpath resource named transformation.json:

from("direct:start").to("jslt:transformation.json");

To include this (an possibly other templates stored in .json files) in the native image, you would have to add something like the following to your application.properties file:

quarkus.native.resources.includes = *.json

2.41.4.2. Using JSLT functions in native mode

When using JSLT functions from camel-quarkus in native mode, the classes hosting the functions would need to be registered for reflection. When registering the target function is not possible, one may end up writing a stub as below.

@RegisterForReflection
public class MathFunctionStub {
    public static double pow(double a, double b) {
        return java.lang.Math.pow(a, b);
    }
}

The target function Math.pow(…) is now accessible through the MathFunctionStub class that could be registered in the component as below:

@Named
JsltComponent jsltWithFunction() throws ClassNotFoundException {
    JsltComponent component = new JsltComponent();
    component.setFunctions(singleton(wrapStaticMethod("power", "org.apache.cq.example.MathFunctionStub", "pow")));
    return component;
}

2.42. Kafka

Sent and receive messages to/from an Apache Kafka broker.

2.42.1. What’s inside

Kafka component, URI syntax: kafka:topic

Please refer to the above link for usage and configuration details.

2.42.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>

    <artifactId>camel-quarkus-kafka</artifactId>
</dependency>

2.42.3. Usage

2.42.3.1. Quarkus Kafka Dev Services

Camel Quarkus Kafka can take advantage of Quarkus Kafka Dev services to simplify development and testing with a local containerized Kafka broker.

Kafka Dev Services is enabled by default in dev & test mode. The Camel Kafka component is automatically configured so that the brokers component option is set to point at the local containerized Kafka broker. Meaning that there’s no need to configure this option yourself.

This functionality can be disabled with the configuration property quarkus.kafka.devservices.enabled=false.

2.42.4. Additional Camel Quarkus configuration

Configuration property Type Default

Configuration property	Type	Default
`quarkus.camel.kafka.kubernetes-service-binding.merge-configuration` If `true` then any Kafka configuration properties discovered by the Quarkus Kubernetes Service Binding extension (if configured) will be merged with those set via Camel Kafka component or endpoint options. If `false` then any Kafka configuration properties discovered by the Quarkus Kubernetes Service Binding extension are ignored, and all of the Kafka component configuration is driven by Camel.	`boolean`	`true`

quarkus.camel.kafka.kubernetes-service-binding.merge-configuration

If true then any Kafka configuration properties discovered by the Quarkus Kubernetes Service Binding extension (if configured) will be merged with those set via Camel Kafka component or endpoint options. If false then any Kafka configuration properties discovered by the Quarkus Kubernetes Service Binding extension are ignored, and all of the Kafka component configuration is driven by Camel.

2.43. Kamelet

Materialize route templates

2.43.1. What’s inside

Kamelet component, URI syntax: kamelet:templateId/routeId

Please refer to the above link for usage and configuration details.

2.43.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-kamelet</artifactId>
</dependency>

2.43.3. Usage

2.43.3.1. Pre-load Kamelets at build-time

This extension allows to pre-load a set of Kamelets at build time using the quarkus.camel.kamelet.identifiers property.

2.43.3.2. Using the Kamelet Catalog

A set of pre-made Kamelets can be found on the /camel-kamelets/latest[Kamelet Catalog]. To use the Kamelet from the catalog you need to copy their yaml definition (that you can find in the camel-kamelet repo) on your project in the classpath. Alternatively you can add the camel-kamelets-catalog artifact to your pom.xml:

<dependency>
    <groupId>org.apache.camel.kamelets</groupId>
    <artifactId>camel-kamelets-catalog</artifactId>
</dependency>

This artifact add all the kamelets available in the catalog to your Camel Quarkus application for build time processing. If you include it with the scope provided the artifact should not be part of the runtime classpath, but at build time, all the kamelets listed via quarkus.camel.kamelet.identifiers property should be preloaded.

2.43.4. Additional Camel Quarkus configuration

Configuration property Type Default

Configuration property	Type	Default
`quarkus.camel.kamelet.identifiers` List of kamelets identifiers to pre-load at build time. Each individual identifier is used to set the related `org.apache.camel.model.RouteTemplateDefinition` id.	`string`

2.44. Kubernetes

Perform operations against Kubernetes API

2.44.1. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-kubernetes</artifactId>
</dependency>

2.44.2. Additional Camel Quarkus configuration

Important

In this release of Camel Extensions for Quarkus, the camel-quarkus-kubernetes extension is only supported when used with the camel-quarkus-master extension as a cluster service. Additionally, in order for the camel-quarkus-kubernetes extension to be supported, you must explicitly add a dependency on the quarkus-openshift-client extension in your application.

2.44.2.1. Automatic registration of a Kubernetes Client instance

The extension automatically registers a Kubernetes Client bean named kubernetesClient. You can reference the bean in your routes like this:

from("direct:pods")
    .to("kubernetes-pods:///?kubernetesClient=#kubernetesClient&operation=listPods")

By default the client is configured from the local kubeconfig file. You can customize the client configuration via properties within application.properties:

quarkus.kubernetes-client.master-url=https://my.k8s.host
quarkus.kubernetes-client.namespace=my-namespace

The full set of configuration options are documented in the Quarkus Kubernetes Client guide.

2.44.2.2. Having only a single consumer in a cluster consuming from a given endpoint

When the same route is deployed on multiple pods, it could be interesting to use this extension in conjunction with the Master one. In such a setup, a single consumer will be active at a time across the whole camel master namespace.

For instance, having the route below deployed on multiple pods:

from("master:ns:timer:test?period=100").log("Timer invoked on a single pod at a time");

It’s possible to enable the kubernetes cluster service with a property like below:

quarkus.camel.cluster.kubernetes.enabled = true

As a result, a single consumer will be active across the ns camel master namespace. It means that, at a given time, only a single timer will generate exchanges across the whole cluster. In other words, messages will be logged every 100ms on a single pod at a time.

The kubernetes cluster service could further be tuned by tweaking quarkus.camel.cluster.kubernetes.* properties.

Configuration property	Type	Default
`quarkus.camel.cluster.kubernetes.enabled` Whether a Kubernetes Cluster Service should be automatically configured according to 'quarkus.camel.cluster.kubernetes.*' configurations.	`boolean`	`false`
`quarkus.camel.cluster.kubernetes-id` The cluster service ID (defaults to null).	`string`
`quarkus.camel.cluster.kubernetes.master-url` The URL of the Kubernetes master (read from Kubernetes client properties by default).	`string`
`quarkus.camel.cluster.kubernetes.connection-timeout-millis` The connection timeout in milliseconds to use when making requests to the Kubernetes API server.	`java.lang.Integer`
`quarkus.camel.cluster.kubernetes.namespace` The name of the Kubernetes namespace containing the pods and the configmap (autodetected by default).	`string`
`quarkus.camel.cluster.kubernetes.pod-name` The name of the current pod (autodetected from container host name by default).	`string`
`quarkus.camel.cluster.kubernetes.jitter-factor` The jitter factor to apply in order to prevent all pods to call Kubernetes APIs in the same instant (defaults to 1.2).	`java.lang.Double`
`quarkus.camel.cluster.kubernetes.lease-duration-millis` The default duration of the lease for the current leader (defaults to 15000).	`java.lang.Long`
`quarkus.camel.cluster.kubernetes.renew-deadline-millis` The deadline after which the leader must stop its services because it may have lost the leadership (defaults to 10000).	`java.lang.Long`
`quarkus.camel.cluster.kubernetes.retry-period-millis` The time between two subsequent attempts to check and acquire the leadership. It is randomized using the jitter factor (defaults to 2000).	`java.lang.Long`
`quarkus.camel.cluster.kubernetes-order` Service lookup order/priority (defaults to 2147482647).	`java.lang.Integer`
`quarkus.camel.cluster.kubernetes.resource-name` The name of the lease resource used to do optimistic locking (defaults to 'leaders'). The resource name is used as prefix when the underlying Kubernetes resource can manage a single lock.	`string`
`quarkus.camel.cluster.kubernetes.lease-resource-type` The lease resource type used in Kubernetes, either 'config-map' or 'lease' (defaults to 'lease').	`org.apache.camel.component.kubernetes.cluster.LeaseResourceType`
`quarkus.camel.cluster.kubernetes.rebalancing` Whether the camel master namespace leaders should be distributed evenly across all the camel contexts in the cluster.	`boolean`	`true`
`quarkus.camel.cluster.kubernetes-labels` The labels key/value used to identify the pods composing the cluster, defaults to empty map.	`Map<String,String>`

2.49.3. Usage

By default, classes extending AbstractHealthCheck are registered as both liveness and readiness checks. You can override the isReadiness method to control this behaviour.

Any checks provided by your application are automatically discovered and bound to the Camel registry. They will be available via the Quarkus health endpoints /q/health/live and /q/health/ready.

You can also provide custom HealthCheckRepository implementations and these are also automatically discovered and bound to the Camel registry for you.

Refer to the Quarkus health guide for further information.

2.49.3.1. Provided health checks

Some checks are automatically registered for your application.

2.49.3.1.1. Camel Context Health

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-mock</artifactId>
</dependency>

2.52.3. Usage

To use camel-mock capabilities in tests it is required to get access to MockEndpoint instances.

CDI injection could be used for accessing instances (see Quarkus documentation). You can inject camelContext into test using @Inject annotation. Camel context can be then used for obtaining mock endpoints. See the following example:

import javax.inject.Inject;

import org.apache.camel.CamelContext;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.component.mock.MockEndpoint;
import org.junit.jupiter.api.Test;

import io.quarkus.test.junit.QuarkusTest;

@QuarkusTest
public class MockJvmTest {

    @Inject
    CamelContext camelContext;

    @Inject
    ProducerTemplate producerTemplate;

    @Test
    public void test() throws InterruptedException {

        producerTemplate.sendBody("direct:start", "Hello World");

        MockEndpoint mockEndpoint = camelContext.getEndpoint("mock:result", MockEndpoint.class);
        mockEndpoint.expectedBodiesReceived("Hello World");

        mockEndpoint.assertIsSatisfied();
    }
}

Route used for the example test:

import javax.enterprise.context.ApplicationScoped;

import org.apache.camel.builder.RouteBuilder;

@ApplicationScoped
public class MockRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("direct:start").to("mock:result");
    }
}

2.52.4. Camel Quarkus limitations

Injection of CDI beans (described in Usage) does not work in native mode.

In the native mode the test and the application under test are running in two different processes and it is not possible to share a mock bean between them (see Quarkus documentation).

2.53. MongoDB

Perform operations on MongoDB documents and collections.

2.53.1. What’s inside

MongoDB component, URI syntax: mongodb:connectionBean

Please refer to the above link for usage and configuration details.

2.53.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-mongodb</artifactId>
</dependency>

2.53.3. Additional Camel Quarkus configuration

The extension leverages the Quarkus MongoDB Client extension. The Mongo client can be configured via the Quarkus MongoDB Client configuration options.

The Camel Quarkus MongoDB extension automatically registers a MongoDB client bean named camelMongoClient. This can be referenced in the mongodb endpoint URI connectionBean path parameter. For example:

from("direct:start")
.to("mongodb:camelMongoClient?database=myDb&collection=myCollection&operation=findAll")

If your application needs to work with multiple MongoDB servers, you can create a "named" client and reference in your route by injecting a client and the related configuration as explained in the Quarkus MongoDB extension client injection. For example:

//application.properties
quarkus.mongodb.mongoClient1.connection-string = mongodb://root:example@localhost:27017/

//Routes.java

    @ApplicationScoped
    public class Routes extends RouteBuilder {
        @Inject
        @MongoClientName("mongoClient1")
        MongoClient mongoClient1;

        @Override
        public void configure() throws Exception {
            from("direct:defaultServer")
                .to("mongodb:camelMongoClient?database=myDb&collection=myCollection&operation=findAll")

            from("direct:otherServer")
                .to("mongodb:mongoClient1?database=myOtherDb&collection=myOtherCollection&operation=findAll");
        }
    }

Note that when using named clients, the "default" camelMongoClient bean will still be produced. Refer to the Quarkus documentation on Multiple MongoDB Clients for more information.

2.54. Netty

2.55. OpenAPI Java

Expose OpenAPI resources defined in Camel REST DSL

2.55.1. What’s inside

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-openapi-java</artifactId>
</dependency>

2.55.3. Usage

You can use this extension to expose REST DSL services to Quarkus OpenAPI. With quarkus-smallrye-openapi, you can access them by /q/openapi?format=json.

Refer to the Quarkus OpenAPI guide for further information.

This is an experimental feature. You can enable it by

quarkus.camel.openapi.expose.enabled=true

Warning

It’s the user’s responsibility to use @RegisterForReflection to register all model classes for reflection.

It doesn’t support the rest services used in org.apache.camel.builder.LambdaRouteBuilder right now. Also, it can not use CDI injection in the RouteBuilder configure() since we get the rest definitions at build time while CDI is unavailable.

2.55.4. Camel Quarkus limitations

The apiContextIdListing configuration option is not supported. Since multiple CamelContext`s are not supported and Quarkus applications run standalone, there is no scenario where attempting to resolve OpenApi specifications for a specific `CamelContext would be useful. It also introduces some additional overhead of requiring JMX (which is not supported in native mode) & additional Camel Quarkus extensions for processing XML.

2.56. OpenTelemetry

Distributed tracing using OpenTelemetry

2.56.1. What’s inside

OpenTelemetry

Please refer to the above link for usage and configuration details.

2.56.2. Maven coordinates

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-opentelemetry</artifactId>
</dependency>

2.56.3. Usage

The extension automatically creates a Camel OpenTelemetryTracer and binds it to the Camel registry.

In order to send the captured traces to a tracing system, you need to configure some properties within application.properties like those below.

# Identifier for the origin of spans created by the application
quarkus.application.name=my-camel-application

# For OTLP
quarkus.opentelemetry.tracer.exporter.otlp.endpoint=http://localhost:4317

# For Jaeger
quarkus.opentelemetry.tracer.exporter.jaeger.endpoint=http://localhost:14250

Note that you must add a dependency to the OpenTelemetry exporter that you want to work with.

Refer to the Quarkus OpenTelemetry guide for a full list of configuration options.

Route endpoints can be excluded from tracing by configuring a property named quarkus.camel.opentelemetry.exclude-patterns in application.properties. For example:

# Exclude all direct & netty-http endpoints from tracing
quarkus.camel.opentelemetry.exclude-patterns=direct:*,netty-http:*

2.56.4. Additional Camel Quarkus configuration

2.59. Platform HTTP

This extension allows for creating HTTP endpoints for consuming HTTP requests.

It is built on top of the Eclipse Vert.x HTTP server provided by the quarkus-vertx-http extension.

2.59.1. What’s inside

Platform HTTP component, URI syntax: platform-http:path

Please refer to the above link for usage and configuration details.

2.59.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-platform-http</artifactId>
</dependency>

2.59.3. Usage

2.59.3.1. Basic Usage

Serve all HTTP methods on the /hello endpoint:

from("platform-http:/hello").setBody(simple("Hello ${header.name}"));

Serve only GET requests on the /hello endpoint:

from("platform-http:/hello?httpMethodRestrict=GET").setBody(simple("Hello ${header.name}"));

2.59.3.2. Using `platform-http` via Camel REST DSL

To be able to use Camel REST DSL with the platform-http component, add camel-quarkus-rest to your pom.xml:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-rest</artifactId>
</dependency>

Then you can use the Camel REST DSL:

rest()
    .get("/my-get-endpoint")
        .to("direct:handleGetRequest");

    .post("/my-post-endpoint")
        .to("direct:handlePostRequest");

2.59.3.3. Handling `multipart/form-data` file uploads

You can restrict the uploads to certain file extensions by white listing them:

from("platform-http:/upload/multipart?fileNameExtWhitelist=html,txt&httpMethodRestrict=POST")
    .to("log:multipart")
    .process(e -> {
        final AttachmentMessage am = e.getMessage(AttachmentMessage.class);
        if (am.hasAttachments()) {
            am.getAttachments().forEach((fileName, dataHandler) -> {
                try (InputStream in = dataHandler.getInputStream()) {
                    // do something with the input stream
                } catch (IOException ioe) {
                    throw new RuntimeException(ioe);
                }
            });
        }
    });

2.59.3.4. Securing `platform-http` endpoints

Quarkus provides a variety of security and authentication mechanisms which can be used to secure platform-http endpoints. Refer to the Quarkus Security documentation for further details.

Within a route, it is possible to obtain the authenticated user and its associated SecurityIdentity and Principal:

from("platform-http:/secure")
    .process(e -> {
        Message message = e.getMessage();
        QuarkusHttpUser user = message.getHeader(VertxPlatformHttpConstants.AUTHENTICATED_USER, QuarkusHttpUser.class);
        SecurityIdentity securityIdentity = user.getSecurityIdentity();
        Principal principal = securityIdentity.getPrincipal();
        // Do something useful with SecurityIdentity / Principal. E.g check user roles etc.
    });

Also check the quarkus.http.body.* configuration options in Quarkus documentation, esp. quarkus.http.body.handle-file-uploads, quarkus.http.body.uploads-directory and quarkus.http.body.delete-uploaded-files-on-end.

2.59.3.5. Implementing a reverse proxy

Platform HTTP component can act as a reverse proxy, in that case Exchange.HTTP_URI, Exchange.HTTP_HOST headers are populated from the absolute URL received on the request line of the HTTP request.

Here’s an example of a HTTP proxy that simply redirects the Exchange to the origin server.

from("platform-http:proxy")
    .toD("http://"
        + "${headers." + Exchange.HTTP_HOST + "}");

2.59.4. Additional Camel Quarkus configuration

2.59.4.1. Platform HTTP server configuration

Configuration of the platform HTTP server is managed by Quarkus. Refer to the Quarkus HTTP configuration guide for the full list of configuration options.

To configure SSL for the Platform HTTP server, follow the secure connections with SSL guide. Note that configuring the server for SSL with SSLContextParameters is not currently supported.

2.59.4.2. Character encodings

Check the Character encodings section of the Native mode guide if you expect your application to send or receive requests using non-default encodings.

2.60. Protobuf Jackson

Marshal POJOs to Protobuf and back using Jackson.

2.60.1. What’s inside

Protobuf Jackson data format

Please refer to the above link for usage and configuration details.

2.60.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-jackson-protobuf</artifactId>
</dependency>

2.61. Quartz

Schedule sending of messages using the Quartz 2.x scheduler.

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-quartz</artifactId>
</dependency>

2.61.3. Usage

2.62. Ref

Route messages to an endpoint looked up dynamically by name in the Camel Registry.

2.62.1. What’s inside

Ref component, URI syntax: ref:name

Please refer to the above link for usage and configuration details.

2.62.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-ref</artifactId>
</dependency>

2.62.3. Usage

CDI producer methods can be harnessed to bind endpoints to the Camel registry, so that they can be resolved using the ref URI scheme in Camel routes.

For example, to produce endpoint beans:

@ApplicationScoped
public class MyEndpointProducers {
    @Inject
    CamelContext context;

    @Singleton
    @Produces
    @Named("endpoint1")
    public Endpoint directStart() {
        return context.getEndpoint("direct:start");
    }

    @Singleton
    @Produces
    @Named("endpoint2")
    public Endpoint logEnd() {
        return context.getEndpoint("log:end");
    }
}

Use ref: to refer to the names of the CDI beans that were bound to the Camel registry:

public class MyRefRoutes extends RouteBuilder {
    @Override
    public void configure() {
        // direct:start -> log:end
        from("ref:endpoint1")
            .to("ref:endpoint2");
    }
}

2.63. Rest

Expose REST services and their OpenAPI Specification or call external REST services.

2.63.1. What’s inside

REST component, URI syntax: rest:method:path:uriTemplate
REST API component, URI syntax: rest-api:path

Please refer to the above links for usage and configuration details.

2.63.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-rest</artifactId>
</dependency>

2.63.3. Additional Camel Quarkus configuration

This extension depends on the Platform HTTP extension and configures it as the component that provides the REST transport.

2.63.3.1. Path parameters containing special characters with platform-http

When using the platform-http REST transport, some characters are not allowed within path parameter names. This includes the '-' and '$' characters.

In order to make the below example REST /dashed/param route work correctly, a system property is required io.vertx.web.route.param.extended-pattern=true.

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() {
        rest("/api")
            // Dash '-' is not allowed by default
            .get("/dashed/param/{my-param}")
            .to("direct:greet")

            // The non-dashed path parameter works by default
            .get("/undashed/param/{myParam}")
            .to("direct:greet");

            from("direct:greet")
                .setBody(constant("Hello World"));
    }
}

There is some more background to this in the Vert.x Web documentation.

2.63.3.2. Configuring alternate REST transport providers

To use another REST transport provider, such as netty-http or servlet, you need to add the respective extension as a dependency to your project and set the provider in your RouteBuilder. E.g. for servlet, you’d have to add the org.apache.camel.quarkus:camel-quarkus-servlet dependency and the set the provider as follows:

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() {
        restConfiguration()
                .component("servlet");
        ...
    }
}

2.64. REST OpenApi

Configure REST producers based on an OpenAPI specification document delegating to a component implementing the RestProducerFactory interface.

2.64.1. What’s inside

REST OpenApi component, URI syntax: rest-openapi:specificationUri#operationId

Please refer to the above link for usage and configuration details.

2.64.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-rest-openapi</artifactId>
</dependency>

2.64.3. Usage

2.64.3.1. Required Dependencies

A RestProducerFactory implementation must be available when using the rest-openapi extension. The currently known extensions are:

camel-quarkus-http

Maven users will need to add one of these dependencies to their pom.xml, for example:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-http</artifactId>
</dependency>

Depending on which mechanism is used to load the OpenApi specification, additional dependencies may be required. When using the file resource locator, the org.apache.camel.quarkus:camel-quarkus-file extension must be added as a project dependency. When using ref or bean to load the specification, not only must the org.apache.camel.quarkus:camel-quarkus-bean dependency be added, but the bean itself must be annotated with @RegisterForReflection.

When using the classpath resource locator with native code, the path to the OpenAPI specification must be specified in the quarkus.native.resources.includes property of the application.properties file. For example:

quarkus.native.resources.includes=openapi.json

2.65. Salesforce

Communicate with Salesforce using Java DTOs.

2.65.1. What’s inside

</dependency>

2.70.3. Camel Quarkus limitations

Oracle JDBC driver brings some GraalVM native-image configuration that breaks the serialization support in Camel Quarkus and Quarkus in general. See this quarkus issue for more details.

Aggregation repository does not work in native mode with Oracle db, because of this issue.

2.70.4. Additional Camel Quarkus configuration

2.70.4.1. Configuring a DataSource

This extension leverages Quarkus Agroal for DataSource support. Setting up a DataSource can be achieved via configuration properties.

quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=your-username
quarkus.datasource.password=your-password
quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/your-database
quarkus.datasource.jdbc.max-size=16

The Camel SQL component will automatically resolve the DataSource bean from the registry. When configuring multiple datasources, you can specify which one is to be used on an SQL endpoint via the URI options datasource or dataSourceRef. Refer to the SQL component documentation for more details.

2.70.4.1.1. Zero configuration with Quarkus Dev Services

In dev and test mode you can take advantage of Configuration Free Databases. The Camel SQL component will be automatically configured to use a DataSource that points to a local containerized instance of the database matching the JDBC driver type that you have selected.

2.70.4.2. SQL scripts

When configuring sql or sql-stored endpoints to reference script files from the classpath, set the following configuration property to ensure that they are available in native mode.

quarkus.native.resources.includes = queries.sql, sql/*.sql

2.70.4.3. SQL aggregation repository in native mode

In order to use SQL aggregation repositories like JdbcAggregationRepository in native mode, you must enable native serialization support.

In addition, if your exchange bodies are custom types, they must be registered for serialization by annotating their class declaration with @RegisterForReflection(serialization = true).

2.71. Telegram

Send and receive messages acting as a Telegram Bot Telegram Bot API.

2.71.1. What’s inside

Telegram component, URI syntax: telegram:type

Please refer to the above link for usage and configuration details.

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-telegram</artifactId>
</dependency>

2.71.3. SSL in native mode

This extension auto-enables SSL support in native mode. Hence you do not need to add quarkus.ssl.native=true to your application.properties yourself. See also Quarkus SSL guide.

2.72. Timer

Generate messages in specified intervals using java.util.Timer.

2.72.1. What’s inside

Timer component, URI syntax: timer:timerName

Please refer to the above link for usage and configuration details.

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-velocity</artifactId>
</dependency>

2.74.3. Usage

2.74.3.1. Custom body as domain object in the native mode

When using a custom object as message body and referencing its properties in the template in the native mode, all the classes need to be registered for reflection (see the documentation).

Example:

@RegisterForReflection
public interface CustomBody {
}

2.74.4. allowContextMapAll option in native mode

The allowContextMapAll option is not supported in native mode as it requires reflective access to security sensitive camel core classes such as CamelContext & Exchange. This is considered a security risk and thus access to the feature is not provided by default.

2.74.5. Additional Camel Quarkus configuration

This component typically loads Velocity templates from classpath. To make it work also in native mode, you need to explicitly embed the templates in the native executable by using the quarkus.native.resources.includes property.

For instance, the route below would load the Velocity template from a classpath resource named template/simple.vm:

from("direct:start").to("velocity://template/simple.vm");

To include this (an possibly other templates stored in .vm files in the template directory) in the native image, you would have to add something like the following to your application.properties file:

quarkus.native.resources.includes = template/*.vm

2.75. XPath

Evaluates an XPath expression against an XML payload

2.75.1. What’s inside

XPath language

Please refer to the above link for usage and configuration details.

2.75.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-xpath</artifactId>
</dependency>

2.75.3. Additional Camel Quarkus configuration

This component is able to load xpath expressions from classpath resources. To make it work also in native mode, you need to explicitly embed the expression files in the native executable by using the quarkus.native.resources.includes property.

For instance, the route below would load an XPath expression from a classpath resource named myxpath.txt:

from("direct:start").transform().xpath("resource:classpath:myxpath.txt");

To include this (an possibly other expressions stored in .txt files) in the native image, you would have to add something like the following to your application.properties file:

quarkus.native.resources.includes = *.txt

2.76. XQuery

Query and/or transform XML payloads using XQuery and Saxon.

2.76.1. What’s inside

XQuery component, URI syntax: xquery:resourceUri
XQuery language

Please refer to the above links for usage and configuration details.

2.76.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-saxon</artifactId>
</dependency>

2.76.3. Additional Camel Quarkus configuration

This component is able to load XQuery definitions from classpath. To make it work also in native mode, you need to explicitly embed the queries in the native executable by using the quarkus.native.resources.includes property.

For instance, the two routes below load an XQuery script from two classpath resources named myxquery.txt and another-xquery.txt respectively:

from("direct:start").transform().xquery("resource:classpath:myxquery.txt", String.class);
from("direct:start").to("xquery:another-xquery.txt");

To include these (an possibly other queries stored in .txt files) in the native image, you would have to add something like the following to your application.properties file:

quarkus.native.resources.includes = *.txt

2.77. XSLT

Transforms XML payload using an XSLT template.

2.77.1. What’s inside

XSLT component, URI syntax: xslt:resourceUri

Please refer to the above link for usage and configuration details.

2.77.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-xslt</artifactId>
</dependency>

2.77.3. Additional Camel Quarkus configuration

To optimize XSLT processing, the extension needs to know the locations of the XSLT templates at build time. The XSLT source URIs have to be passed via the quarkus.camel.xslt.sources property. Multiple URIs can be separated by comma.

quarkus.camel.xslt.sources = transform.xsl, classpath:path/to/my/file.xsl

Scheme-less URIs are interpreted as classpath: URIs.

Only classpath: URIs are supported on Quarkus native mode. file:, http: and other kinds of URIs can be used on JVM mode only.

<xsl:include> and <xsl:messaging> XSLT elements are also supported in JVM mode only right now.

If aggregate DSL is used, XsltSaxonAggregationStrategy has to be used such as

from("file:src/test/resources?noop=true&sortBy=file:name&antInclude=*.xml")
   .routeId("aggregate").noAutoStartup()
   .aggregate(new XsltSaxonAggregationStrategy("xslt/aggregate.xsl"))
   .constant(true)
   .completionFromBatchConsumer()
   .log("after aggregate body: ${body}")
   .to("mock:transformed");

Also, it’s only supported on JVM mode.

2.77.3.1. Configuration

TransformerFactory features can be configured using following property:

quarkus.camel.xslt.features."http\://javax.xml.XMLConstants/feature/secure-processing"=false

2.77.3.2. Extension functions support

Xalan’s extension functions do work properly only when:

Secure-processing is disabled
Functions are defined in a separate jar
Functions are augmented during native build phase. For example, they can be registered for reflection:

@RegisterForReflection(targets = { my.Functions.class })
public class FunctionsConfiguration {
}

Note

The content of the XSLT source URIs is parsed and compiled into Java classes at build time. These Java classes are the only source of XSLT information at runtime. The XSLT source files may not be included in the application archive at all.
