Make EnableRabbitRetryAndDlq applicable to ElementType.ANNOTATION_TYPE

[antoniobarcelos]

This could be really useful to organize the code because in this way you could define an annotation like this in a configuration package:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@RabbitListener(containerFactory = "event", queues = "${spring.rabbitmq.custom.event.queue}")
@EnableRabbitRetryAndDlq(
        event = "event",
        retryWhen = {},
        discardWhen = {},
        directToDlqWhen = { Exception.class }
)
public @interface EventListener {

}

and the use like this in your application class:

@Service
class MyService {

   @EventListener
   public void onEvent(Event event) {
      //... do something
   }
}
