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-producer.xml文件

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	   xmlns:context="http://www.springframework.org/schema/context"
    	   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
    		http://www.springframework.org/schema/context   
    		http://www.springframework.org/schema/context/spring-context.xsd">
     
    	
    	<context:component-scan base-package="com.demo"/>
     
        
    	<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="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
    	    
    	    <property name="connectionFactory" ref="connectionFactory"/>
    	</bean>
        
    	<bean id="queueTextDestination" class="org.apache.activemq.command.ActiveMQQueue">
    	    <constructor-arg value="queue_text"/>
    	</bean>
     
    	
    	<bean id="topicTextDestination" class="org.apache.activemq.command.ActiveMQTopic">
    	    <constructor-arg value="topic_text"/>
    	</bean>
     
    </beans>

编写TopicProducer类

package com.pinyougou.demo;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.core.JmsTemplate;
    import org.springframework.jms.core.MessageCreator;
    import org.springframework.stereotype.Component;
    
    import javax.jms.Destination;
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.Session;
    
    /**
     * @author lyc
     * @Description:
     * @create 2018-08-22
     */
    @Component
    public class TopicProducer {
    
        @Autowired
        private JmsTemplate jmsTemplate;
    
        @Autowired
        private Destination topicTextDestination;
    
        /**
         * 发送文本消息
         * @param text
         */
        public void sendTextMessage(final String text){
            jmsTemplate.send(topicTextDestination, new MessageCreator() {
                public Message createMessage(Session session) throws JMSException, JMSException {
                    return session.createTextMessage(text);
                }
            });
        }
    
    
    }

编写测试类

package com.test;
    
    import com.demo.TopicProducer;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    /**
     * @author lyc
     * @Description:
     * @create 2018-08-22
     */
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations="classpath:applicationContext-jms-producer.xml")
    public class TestTopic {
        @Autowired
        private TopicProducer topicProducer;
        @Test
        public void sendTextQueue(){
            topicProducer.sendTextMessage("spring jsm 发布订阅");
        }
    
    }

运行测试类，运行成功

再看管理端：成功
