Chapter 11 ■ Integrating Your Spring Application with External Systems Figure 11-5. The Message Is Listed and Ready 150 Figure 11-5 shows the message that you sent to the queue. Spring JMS Next, you are going to create a consumer that will consume that message. The Spring Framework already has a template (for sending JMS messages to any JMS broker) and a Simple Listener container (that connects to a JMS broker and listens for any new messages incoming from a queue or topic). Listing 11-2 shows the consumer you are going to use to consume the XML message from the Apache ActiveMQ container. Listing 11-2.
