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

<!-- 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)

<?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. Serializable class not available to broke-->
        <property name="trustAllPackages" value="true"/>
        <!-- 是否异步发送 -->
        <property name="useAsyncSend" value="true" />
    </bean>
 
    <!--============================监听模块==============-->
    <bean id="queueDestination3" class="org.apache.activemq.command.ActiveMQQueue">
        <!-- 设置消息队列的名字 -->
        <constructor-arg>
            <value>queue3</value>
        </constructor-arg>
    </bean>
 
    <bean id="studentInfoHandler" class="org.soa.test.activemq.listeners.StudentInfoHandler" />
 
    <!-- 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-->
    <bean id="jmsContainer"
          class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destination" ref="queueDestination3" />
        <property name="messageListener" ref="studentInfoHandler" />
    </bean>
</beans>

三、监听代码

1、监听代码

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：\t"+ tm.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

2、测试代码

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");
    }
}
