Multiple Camel contexts support

Configuration properties

Auto-configured type converters

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) {
        //...
    }
}

Note that CDI injection is supported within the type converters.

Camel bean integration

Camel events to CDI events

...

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.

Auto-configured type converters

@Converter
public class MyTypeConverter {

    @Converter

mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes -DarchetypeArtifactId=camel-archetype-cdi

Supported containers

The Camel CDI component is compatible with any CDI 1.0, CDI 1.1 and CDI 1.2 compliant runtime. It's been successfully tested against the following runtimes:

Examples

The following examples are available in the examples directory of the Camel project:

• camel-example-cdi-metrics - illustrates the integration between Camel, Dropwizard Metrics and CDI,
• camel-example-cdi-properties - illustrates the integration between Camel, DeltaSpike and CDI for configuration properties,
• camel-example-cdi-osgi - a CDI application using the SJMS component that can be executed inside an OSGi container using PAX CDI,
• camel-example-cdi-rest-servlet - illustrates the Camel REST DSL being used in a Web application that uses CDI as dependency injection framework,
• camel-example-widget-gadget-cdi - The Widget and Gadget use-case from the EIP book implemented in Java with CDI dependency Injection.
