Spring JMS异步发收消息 ActiveMQ

JMS(使用消息中介：ActiveMQ)
JMS为JAVA开发者提供了一个与消息中介进行交互，以及发送和接收消息的标准API，而且每一个消

息中介的实现都会支持JMS。（即JMS为所有消息中介提供了统一接口）；JmsTemplate是Spring消

除冗长和重复JMS代码的解决方案。JmsTemplate可以创建连接，获取会话，以及发送和接收消息。
1.在Spring中安装ActiveMQ
www.activemq.org    apache-activemq-4.1.0-incubator.zip ，把apache-activemq-4.1.0-

incubator.jar复制到lib中
启动ActiveMQ的脚本：运行刚下载的文件/bin/activemq.bat.  这样就可以使用ActiveMQ进行中介服

务了。
2.applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans
 xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<!--创建连接工厂-->
<bean id="connectionFactory"
  class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616"></property>
</bean>
<!-- 声明ActiveMQ消息目标,目标可以是一个队列，也可以是一个主题ActiveMQTopic-->
<bean id="destination" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg index="0" value="rantz.marketing.queue"></constructor-arg>
</bean>
<!---->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
  <property name="connectionFactory" ref="connectionFactory"></property>
  <property name="defaultDestination" ref="destination"></property>
  <property name="receiveTimeout" value="6000"></property>

</bean>
<bean id="sender" class="com.roadrantz.marketing.Sender">
  <property name="jmsTemplate" ref="jmsTemplate"></property>

</bean>
<bean id="receiver" class="com.roadrantz.marketing.Receiver">
  <property name="jmsTemplate" ref="jmsTemplate"></property>
</bean>
</beans>

3.发送消息Sender.java
package com.roadrantz.marketing;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MapMessage;
import javax.jms.Message;
import javax.jms.Session;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
public class Sender {
 private JmsTemplate jmsTemplate;
   public void sendInfo()
   {
  jmsTemplate.send(new MessageCreator(){
   public Message createMessage(Session session) throws JMSException
   {   MapMessage message=session.createMapMessage();
         message.setString("lastName", "pp");
      return message;
   }
  
  });
   }
public JmsTemplate getJmsTemplate() {
 return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
 this.jmsTemplate = jmsTemplate;
}
}
4.接收消息Receiver.java
package com.roadrantz.marketing;
import javax.jms.JMSException;
import javax.jms.MapMessage;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.support.JmsUtils;
public class Receiver {
   private JmsTemplate jmsTemplate;
   public Receiver() {}
   public String receiveMessage()
 {   String my="";
  MapMessage message=(MapMessage)jmsTemplate.receive();
    try{
     my= message.getString("lastName");
    }
    catch(JMSException e)
    {  throw JmsUtils.convertJmsAccessException(e); }
  return my;
 }
 public JmsTemplate getJmsTemplate() {
  return jmsTemplate;
 }
 public void setJmsTemplate(JmsTemplate jmsTemplate) {
  this.jmsTemplate = jmsTemplate;
 }
5.测试
test.java发
package com.roadrantz.marketing;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class test {
 public static void main(String[] args) {
  // TODO 自动生成方法存根
   ApplicationContext context = new ClassPathXmlApplicationContext

("applicationContext.xml");
   Sender sender = (Sender) context.getBean("sender");
         sender.sendInfo(); 
 }
}
test2.java收
package com.roadrantz.marketing;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class test2 {
 public static void main(String[] args) {
  // TODO 自动生成方法存根
   ApplicationContext context = new ClassPathXmlApplicationContext

("applicationContext.xml");
   Receiver receiver = (Receiver) context.getBean("receiver");
   System.out.print(receiver.receiveMessage());  }
}
