Is it possible to have a single @RabbitListener, e.g:
@RabbitListener(queues = STORAGE_REQUEST_QUEUE_NAME)
public FindApplicationByIdResponse findApplicationById(FindApplicationByIdRequest request) {
return repository.findByUuid(request.getId())
.map(e -> new FindApplicationByIdResponse(conversionService.convert(e, Application.class)))
.orElse(new FindApplicationByIdResponse(null));
}
@RabbitListener(queues = STORAGE_REQUEST_QUEUE_NAME)
public PingResponse ping(PingRequest request) {
return new PingResponse();
}
And on the consumer side, it will send requests to the same request queue, but with different operations? Now it converts the objects from Json to a object (e.g.: FindApplicationByIdRequest, or PingRequest).
But now, when i get it back:
@Override
public FindApplicationByIdResponse findApplicationById(FindApplicationByIdRequest request) {
Object object = template.convertSendAndReceive(Queues.STORAGE_REQUEST_QUEUE_NAME, request);
return handleResponse(FindApplicationByIdResponse.class, object);
}
@Override
public PingResponse ping(PingRequest request) {
Object object = template.convertSendAndReceive(Queues.STORAGE_REQUEST_QUEUE_NAME, request);
return handleResponse(PingResponse.class, object);
}
It looks like it failed to correlate the two. So I call the ping method, then I get a FindApplicationByIdResponse back in that method. Why is that?
When I used different queues for them, it works fine. But I end up having to make a lot of queues to support all the RPC calls I wish to make. Anyone know if its possible to use the request type as a qualifier to which one it's going to use?
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) {
...
}
}
