Package org.springframework.jms.listener.adapter

Class JmsResponse<T>

java.lang.Object

org.springframework.jms.listener.adapter.JmsResponse<T>

Type Parameters:

T - the type of the response

public class JmsResponse<T>
extends Object

Return type of any JMS listener method used to indicate the actual response destination alongside the response itself. Typically used when said destination needs to be computed at runtime.

The example below sends a response with the content of the result argument to the queueOut Queue:

 package com.acme.foo;

 public class MyService {
     @JmsListener
     public JmsResponse process(String msg) {
         // process incoming message
         return JmsResponse.forQueue(result, "queueOut");
     }
 }

If the destination does not need to be computed at runtime, @SendTo is the recommended declarative approach.
