Annotation Type RabbitHandler

@Target({METHOD,ANNOTATION_TYPE})
@Retention(RUNTIME)
@MessageMapping
@Documented
public @interface RabbitHandler

Annotation that marks a method to be the target of a Rabbit message listener within a class that is annotated with RabbitListener.

See the RabbitListener for information about permitted method signatures and available parameters.

It is important to understand that when a message arrives, the method selection depends on the payload type. The type is matched with a single non-annotated parameter, or one that is annotated with @Payload. There must be no ambiguity - the system must be able to select exactly one method based on the payload type.
