不知道如何创建发布订阅生产者的参考：[https://mp.csdn.net/postedit/81948730][https_mp.csdn.net_postedit_81948730]

首先创建一个新的工程，在pom.xml

<properties>
            <spring.version>4.2.4.RELEASE</spring.version>
        </properties>
     
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-jms</artifactId>
                <version>${spring.version}</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-test</artifactId>
                <version>${spring.version}</version>
            </dependency>
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.9</version>
            </dependency>
            <dependency>
                <groupId>org.apache.activemq</groupId>
                <artifactId>activemq-client</artifactId>
                <version>5.13.4</version>
            </dependency>
        </dependencies>

在资源文件包中添加applicationContext-jms-consumer-topic.xml文件

<?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.xsd">
    
    	
    	<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
    		<property name="brokerURL" value="tcp://192.168.25.140:61616"/>
    	</bean>
    	
    	<bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
    		
    		<property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    	</bean>
    	
    	<bean id="topicTextDestination" class="org.apache.activemq.command.ActiveMQTopic">
    		<constructor-arg value="topic_text"/>
    	</bean>
    	
    	<bean id="myMessageListener" class="com.demo.MyMessageListener"></bean>
    	
    	<bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    		<property name="connectionFactory" ref="connectionFactory" />
    		<property name="destination" ref="topicTextDestination" />
    		<property name="messageListener" ref="myMessageListener" />
    	</bean>
    
    </beans>

编写监听器：

package com.demo;
    
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.MessageListener;
    import javax.jms.TextMessage;
    
    /**
     * @author lyc
     * @Description:
     * @create 2018-08-22
     */
    public class MyMessageListener implements MessageListener {
        //监听的message
        public void onMessage(Message message) {
            TextMessage textMessage=(TextMessage)message;
            try {
                System.out.println("接收到消息："+textMessage.getText());
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    
    }

注意配置文件中的监听器地址和你自定义的监听器地址。

编写测试类：

package com.test;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import java.io.IOException;
    
    /**
     * @author lyc
     * @Description:
     * @create 2018-08-22
     */
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations="classpath:applicationContext-jms-consumer-topic.xml")
    public class TestTopic {
    
        @Test
        public void testTopic(){
            try {
                //为了启动进行监听
                System.in.read();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    
    
    }

运行测试类：正在运行

此时我们运行发布订阅的生产者：此时我们收到了信息

![70 1][] 再来观察管理端：已经发生了变化
