Spring与Jms组合的实例

Spring与Jms结合的实例

另见：ActiveMQ5.0实战一: 安装配置ActiveMQ5.0 ActiveMQ5.0实战二: 基本配置 http://www.iteye.com/topic/234101================================================

环境：apache-activemq-5.4.2 ,spring2.5,jdk1.6

首先启动消息代理：在apache-activemq-5.4.2\bin下
运行
activemq.bat。

example1：

package jms.activemq.myexample.spring;

import java.util.Date;

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

import org.springframework.jms.core.MessageCreator;

public class MyMessageCreator implements MessageCreator {

?/**
? * 消息序号
? */
?private int msgNo;

?public MyMessageCreator(int no) {
??this.msgNo = no;
?}

?@Override
?public Message createMessage(Session session) throws JMSException {
??TextMessage textMsg = session.createTextMessage();
??textMsg.setText(new Date() + "第" + this.msgNo + "条消息发出");

??return textMsg;
?}

}

package jms.activemq.myexample.spring;

import javax.jms.*;

/**

????System.out.println("Message of wrong type: "
??????+ message.getClass().getName());
???}
??} catch (JMSException e) {
???System.out.println("JMSException in onMessage(): " + e.toString());
??} catch (Throwable t) {
???System.out.println("Exception in onMessage():" + t.getMessage());
??}
?}
}

????new String[] { "SpringJms/SpringJms.xml" });

??SpringPublisher publisher = (SpringPublisher) context
????.getBean("springPublisher");
??publisher.start();
?}
}

package jms.activemq.myexample.spring;

import javax.jms.Destination;

import org.springframework.jms.core.JmsTemplate;

public class SpringPublisher {
?/**

运行发送端三次：
成功发送了一条JMS消息

Process finished with exit code 0
然后再运行接收端一次：
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！
继续测试发现，接收端接收一条消息后不退出程序，而是继续等待，一旦有消息发送过来，就获取到，然后输出！
