To use class-based injection, decorate the class with a @Resource annotation, and set the required name and type elements.
@Resource(name="myMessageQueue", type="javax.jms.ConnectionFactory") public class SomeMessageBean { ... }
The @Resources annotation is used to group together multiple @Resource declarations for class-based injection.
@Resources({ @Resource(name="myMessageQueue", type="javax.jms.ConnectionFactory"), @Resource(name="myMailSession", type="javax.mail.Session") }) public class SomeMessageBean { ... }
The code above shows the @Resources annotation containing two @Resource declarations. One is a Java Message Service (JMS) message queue, and the other is a JavaMailTM session.
