ActiveMQ_监听器(四)

一、本文章包含的内容

1、列举了ActiveMQ中监听器的使用

2、spring+activemq方式

1 2 3

<!-- 消息监听容器（Queue），配置连接工厂，监听的队列是queue3，监听器是上面定义的监听器 --> <!--加载spring配置后，studentInfoHandler的onMessage方法自动运行并接收队列-->

 

二、配置文件(spring-jms.xml)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xmlns:context="http://www.springframework.org/schema/context"        xmlns:jms="http://www.springframework.org/schema/jms"        xmlns:amq="http://activemq.apache.org/schema/core"        xsi:schemaLocation="                     http://www.springframework.org/schema/beans                     http://www.springframework.org/schema/beans/spring-beans-3.2.xsd                     http://www.springframework.org/schema/context                     http://www.springframework.org/schema/context/spring-context-3.2.xsd                     http://www.springframework.org/schema/jms                     http://www.springframework.org/schema/jms/spring-jms-3.2.xsd">       <!-- 启用spring mvc 注解 -->     <context:component-scan base-package="org.soa.test.activemq"/>       <!-- 配置JMS连接工厂 -->     <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">         <property name="brokerURL" value="failover:(tcp://192.168.146.129:61616)" />         <!--解决接收消息抛出异常：javax.jms.JMSException: Failed to build body from content.

三、监听代码

1、监听代码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

package org.soa.test.activemq.listeners;   import org.soa.test.activemq.StudentInfo;   import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage;   /**  * Created by JamesC on 16-9-22.  */ public class StudentInfoHandler implements MessageListener {       //加载spring配置后，studentInfoHandler的onMessage方法自动运行并接收队列     @Override     public void onMessage(Message message) {         TextMessage tm = (TextMessage) message;         try {             System.out.println("ConsumerMessageListener收到了文本消息： "+ tm.getText());         } catch (JMSException e) {             e.printStackTrace();         }     } }

2、测试代码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

package org.soa.test.activemq.listeners;   import org.junit.Test; import org.junit.runner.RunWith; import org.soa.test.activemq.queues.ProduceMsg; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;   import javax.jms.Destination;   /**  * Created by JamesC on 16-9-22.  */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("/spring-jms.xml") public class ListenerTest {       @Autowired     @Qualifier("queueDestination3")//配置文件中只配置了接收queueDestination3的消息     private Destination destination;       @Autowired     private ProduceMsg produceMsg;       @Test     public void sendMsg(){         produceMsg.sendMessage(destination,"----这里测试使用配置实现监听器测试消息接收");     } }
