在Spring下集成ActiveMQ
1.参考文献
2.环境
在前面的一篇ActiveMQ入门实例中我们实现了消息的异步传送，这篇博文将如何在spring环境下集成ActiveMQ。如果要在spring下集成ActiveMQ，那么就需要将如下jar包导入项目：
本文有两篇参考文献，因此有两个实例，项目结构如下图所示：
3.实例1
信息发送者：HelloSender.java
package edu.sjtu.erplab.springactivemq;
import javax.jms.JMSException;
import javax.jms.Session;
import javax.jms.Destination;
import javax.jms.Message;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
public class HelloSender {
/**
* @param args
* jmsTemplate和destination都是在spring配置文件中进行配制的
* Sender只使用了配置文件中的jmsFactory，jmsTemplate，还有destination这三个属性
*/
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
JmsTemplate template = (JmsTemplate) applicationContext.getBean("jmsTemplate");
Destination destination = (Destination) applicationContext.getBean("destination");
template.send(destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("发送消息：Hello ActiveMQ Text Message2！");
}
});
System.out.println("成功发送了一条JMS消息");
}
}
信息接受者：ProxyJMSConsumer.java
package edu.sjtu.erplab.springactivemq;
import javax.jms.Destination;
import javax.jms.TextMessage;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
/**
* JMS消费者
* 消息题的内容定义
* 消息对象 接收消息对象后： 接收到的消息体* <p>
*/
public class ProxyJMSConsumer {
public ProxyJMSConsumer() {
}
private JmsTemplate jmsTemplate;
public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
/**
* 监听到消息目的有消息后自动调用onMessage(Message message)方法
*/
public void recive() {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
Destination destination = (Destination) applicationContext.getBean("destination");
while (true) {
try {
TextMessage txtmsg = (TextMessage) jmsTemplate
.receive(destination);
if (null != txtmsg) {
System.out.println("[DB Proxy] " + txtmsg);
System.out.println("[DB Proxy] 收到消息内容为: "
+ txtmsg.getText());
} else
break;
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
客户端：JMSTest.java
package edu.sjtu.erplab.springactivemq;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class JMSTest {
/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext.getBean("messageReceiver");
proxyJMSConsumer.recive();
System.out.println("初始化消息消费者");
}
}
Spring配置文件：applicationContext-jms.xml

测试方法：首先运行JMSTest，然后运行HelloSender。

return my;
