Single Queue, multiple @RabbitListener but different services

Question

Is it possible to have a single @RabbitListener, e.g:

@RabbitListener(queues = STORAGE_REQUEST_QUEUE_NAME)
public FindApplicationByIdResponse findApplication         


        

Answer 1

That doesn't work with @RabbitListener on the method level, but it is possible on the class level with the @RabbitHandler on methods:

@RabbitListener(queues = STORAGE_REQUEST_QUEUE_NAME)
public class MultiListenerBean {

    @RabbitHandler
    public String bar(Bar bar) {
        ...
    }

    @RabbitHandler
    public String baz(Baz baz) {
        ...
    }

    @RabbitHandler
    public String qux(@Header("amqp_receivedRoutingKey") String rk, @Payload Qux qux) {
        ...
    }

}
