本文介绍了如何使用Spring框架整合消息队列（MQ），包括发送消息的实现方式和监听消息的配置方法。通过示例代码展示了如何创建消息发送者和接收者，以及如何配置ActiveMQ连接工厂和监听容器。

一、spring对MQ的支持

注：要添加事务的jar

package org.nick.mq;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

public class Sender {
  public static void main(String args[]) throws Exception {
    ApplicationContext context = new ClassPathXmlApplicationContext(
        new String[] { "conf/beans.xml" });
    JmsTemplate jmsTemplate = (JmsTemplate) context.getBean("jmsTemplate");
    Destination destination = (Destination) context.getBean("destination");
    jmsTemplate.send(destination, new MessageCreator() {
      public Message createMessage(Session session) throws JMSException {
        return session.createTextMessage("大家好这个是测试！");
      }
    });
  }
}

package org.nick.mq;

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

public class MQlistener implements MessageListener {

	  public void onMessage(Message message) {
	    // TODO Auto-generated method stub
	    TextMessage msg=null;
	    try {
	      if(message instanceof TextMessage){
	        msg=(TextMessage)message;
	        System.out.println("Reading message:"+msg.getText());
	      } else {
	                System.out.println("Message of wrong type: "
	                        + message.getClass().getName());
	            }
	    } catch (JMSException e) {
	      // TODO: handle exception
	      System.out.println("JMSEXCEPTION:"+e.toString());
	    } catch (Throwable e) {
	      // TODO: handle exception
	      System.out.println("EXCEPTION:"+e.getMessage());
	    }
	  }

	}
