1.controller

@Controller
@RequestMapping( "/test")
public class TestController  {
    @Resource(name= "jmsTemplate")
    private JmsTemplate  jmsTemplate;
    @Resource(name= "jmsTemplate2")
    private JmsTemplate  jmsTemplate2;

    @RequestMapping(value =  "/send")
    public void sendmessage(){
        Examination examination= new Examination();
        examination.setSno( "学校");
        TestMessage testMessage =  new TestMessage();
        jmsTemplate.send(testMessage);
        jmsTemplate.convertAndSend(examination);
        jmsTemplate2.convertAndSend(examination);
    }

}

2.converter

public class ExaminationMessageConverter  implements MessageConverter {
    @Override
    public Object fromMessage(Message message)  throws JMSException,
            MessageConversionException {
        if(!(message  instanceof MapMessage)){
            throw new MessageConversionException( "Message isn't a MapMessage");
        }
        MapMessage msg = (MapMessage)message;
        //Examination为实体类
        Examination messageDescription =  new Examination();
        messageDescription.setSno(msg.getString( "sno"));
        return messageDescription;
    }

    @Override
    public Message toMessage(Object object, Session session)  throws JMSException,
            MessageConversionException {
        if(!(object  instanceof Examination)){
            throw new MessageConversionException( "Object isn't a Examination");
        }
        Examination messageDescription = (Examination)object;
        MapMessage message = session.createMapMessage();
        message.setString( "sno", messageDescription.getSno());
        return message;
    }

}

3.entity 

public class Examination {
    private  String  sno;

    public  String getSno() {
        return  sno;
    }

    public void setSno( String sno) {
        this. sno = sno;
    }

}

4.listener

public class FilterListener  implements MessageListener {
    @Autowired
    private  ExaminationMessageConverter  examinationMessageConverter;

    @Override
    public void onMessage(Message msg) {
        try {
            Examination entity=(Examination) examinationMessageConverter.fromMessage(msg);
            System. out.println( "1号监听器收到消息："+entity.getSno());
        }  catch (JMSException e) {
            e.printStackTrace();
        }
    }

}

5.message

public class TestMessage  implements MessageCreator {

    @Override
    public Message createMessage(Session session)  throws JMSException {
        MapMessage message = session.createMapMessage();
        message.setJMSMessageID( "101");
        return message;
    }

}
