使用Spring2.0发送和接受JMS消息

使用Spring2.0发送和接受JMS消息

1.JmsQueueSender类,用于发送消息

package  com.sitinspring.springjms;

import  javax.jms.ConnectionFactory;
import  javax.jms.JMSException;
import  javax.jms.Message;
import  javax.jms.Queue;
import  javax.jms.Session;

import  org.springframework.context.ApplicationContext;
import  org.springframework.context.support.FileSystemXmlApplicationContext;
import  org.springframework.jms.core.JmsTemplate;
import  org.springframework.jms.core.JmsTemplate102;
import  org.springframework.jms.core.MessageCreator;

public   class  JmsQueueSender  {

    private JmsTemplate jmsTemplate;

    private Queue queue;

    public void setConnectionFactory(ConnectionFactory cf) {
        this.jmsTemplate = new JmsTemplate102(cf, false);
    }

    public void setQueue(Queue queue) {
        this.queue = queue;
    }

    public void simpleSend() {
        this.jmsTemplate.send(this.queue, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("hello queue world");
            }
        });
    }
    
    public static void main(String[] args){
        
        ApplicationContext appContext = new FileSystemXmlApplicationContext("spring-jms.xml");

        JmsQueueSender jmsSender = (JmsQueueSender)appContext.getBean("jmsQueueSender");        
        jmsSender.simpleSend();
    }
}

2.ExampleListener,用于接受消息,他是一个Message Driven Pojo.

package  com.sitinspring.springjms;

import  javax.jms.JMSException;
import  javax.jms.Message;
import  javax.jms.MessageListener;
import  javax.jms.TextMessage;

public   class  ExampleListener  implements  MessageListener  {

    public void onMessage(Message message) {
        //org.springframework.jms.listener.DefaultMessageListenerContainer102
        if (message instanceof TextMessage) {
            System.out.print("I have received a msg:");
            try {
                System.out.println(((TextMessage) message).getText());
            } catch (JMSException ex) {
                throw new RuntimeException(ex);
            }
        } else {
            throw new IllegalArgumentException(
                    "Message must be of type TextMessage");
        }
    }
}

3.配置文件spring-jms.xml,所有配置均在其中.
值得注意的是标有102处,如果你使用的是DefaultMessageListenerContainer,你将为异常所困扰.
