Messaging

Abstract

In this chapter, you will learn about Spring’s support for Java Message Service (JMS). JMS defines a set of standard APIs for message-oriented communication (using “message-oriented middleware,” a.k.a MOM) in the Java EE platform. With JMS, different applications can communicate in a loosely coupled way compared with other remoting technologies such as RMI. However, when using the JMS API to send and receive messages, you have to manage the JMS resources yourself and handle the JMS API’s exceptions, which results in many lines of JMS-specific code. Spring simplifies JMS’s usage with a template-based approach, just as it does for JDBC. Moreover, Spring enables beans declared in its IoC container to listen for JMS messages and react to them.
