How to receive what was sent by convertAndSend?

Question

I'm reading Spring Framework reference, chapter about JMS integration. There are some examples for sending text messages and asynchronously receiving them (by listeners). And there is also an example for JmsTemplate function convertAndSend which converts given object to a message. The reference says:

By using the converter, you and your application code can focus on the business object that is being sent or received via JMS and not be concerned with the details of how it is represented as a JMS message.

But there is no example for receiving such messages. They mention function receiveAndConvert but, unfortunately, it receives synchronously.
So how am I to receive it asynchronously? Must I be aware that when I convertAndSend a Map, the resulting message will be a MapMessage, and just check in my listener for this type of message and handle it? But they promised I'm not to be concerned with the details of how it is represented as a JMS message.
So is there a better way?

Answer 1

While JmsTemplate provides basic synchronous receive methods, asynchronous reception is a whole lot more complicated, and is beyond the scope of JmsTemplate.

Asynchronous reception of JMS messages is done in Spring using Message Listener Containers, which asynchronously take messages from the JMS destination and pass them to your application. You can plug a MessageConverter in to your message listener container via the MessageListenerAdapter class (plug the converter into the adapter, plug your application's listener into the adapter, then plug the adapter into the listener container).
