How do we use uri endpoint mapping in spring integration - web-services

Question

I am trying to configure spring integration using annotation. Instead of payloadqnameendpoint mapping I would like to use URI endpoint mapping. I found many examples with default URI endpoint but I required an annotation example without default end point.

Let's take a look to the AnnotationActionEndpointMapping support in the Spring WS! As you see it is based on the division between POJO methods and annotations on the them. The POJO is a main word there. This kind of framework magic allow us to separate low-level protocol from end-application business logic. From other side Spring Integration's AbstractWebServiceInboundGateway implements MessageEndpoint meaning that the whole SOAP hard work will be done in this implementation. It isn't a POJO.
Of course this topic is a different story, but you should understand from here that MessageEndpoint and MethodEndpoint work a bit different. At least they do messaging logic from different levels of SOAP request.
So, we really can't map <int-ws:inbound-gateway> with #Action or similar just because it is a whole SOAP endpoint already.
From other side, having AnnotationActionEndpointMapping from Java config, you can fully get rid of <int-ws:inbound-gateway> and configure your Endpoint to delegate desired #Action to the methods of #MessagingGateway. And it will work beucase the hard SOAP work has been done already by Spring WS framework.
I don't know you that this code will work, but you can check or let me know and I'll test it and come back to again:
#Endpoint
#MessagingGateway
public interface OrderEndpoint {
#Action("http://samples/RequestOrder")
#Gateway(requestChannel = "getOrderChannel")
Order getOrder(OrderRequest orderRequest);
#Action("http://samples/CreateOrder")
#Gateway(requestChannel = "createOrderChannel")
void order(Order order);
}
