1、导入jar包

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
    </dependency>
    <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
    </dependency>

2、发送消息  
配置Activemq整合spring，配置ConnectionFactory  
配置生产者，使用JMSTemplate对象发送消息  
在spring容器中配置Destination。

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
    
        
        <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL" value="tcp://192.168.25.168:61616" />
        </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="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
            <constructor-arg>
                <value>spring-queue</value>
            </constructor-arg>
        </bean>
        
        <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
            <constructor-arg value="topic" />
        </bean>
    </beans>

3、代码测试  
第一步：初始化一个spring容器  
第二步：从容器中获得JMSTemplate对象。  
第三步：从容器中获得一个Destination对象  
第四步：使用JMSTemplate对象发送消息，需要知道Destination

@Test
        public void testQueueProducer() throws Exception {
            // 第一步：初始化一个spring容器
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
            // 第二步：从容器中获得JMSTemplate对象。
            JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class);
            // 第三步：从容器中获得一个Destination对象
            Queue queue = (Queue) applicationContext.getBean("queueDestination");
            // 第四步：使用JMSTemplate对象发送消息，需要知道Destination
            jmsTemplate.send(queue, new MessageCreator() {
    
                @Override
                public Message createMessage(Session session) throws JMSException {
                    TextMessage textMessage = session.createTextMessage("spring activemq test");
                    return textMessage;
                }
            });
        }

4、接收消息  
第一步：把Activemq相关的jar包添加到工程中。  
第二步：创建一个MessageListener的实现类。

public class MyMessageListener implements MessageListener { 
    
        @Override
        public void onMessage(Message message) {
    
            try {
                TextMessage textMessage = (TextMessage) message;
                //取消息内容
                String text = textMessage.getText();
                System.out.println(text);
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    
    }

第三步：配置spring和Activemq整合。

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
    
        
        <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL" value="tcp://192.168.25.168:61616" />
        </bean>
        
        <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
            
            <property name="targetConnectionFactory" ref="targetConnectionFactory" />
        </bean>
        
        <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
            <constructor-arg>
                <value>spring-queue</value>
            </constructor-arg>
        </bean>
        
        <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
            <constructor-arg value="topic" />
        </bean>
        
        
        <bean id="myMessageListener" class="com.taotao.search.listener.MyMessageListener" />
        
        <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
            <property name="connectionFactory" ref="connectionFactory" />
            <property name="destination" ref="queueDestination" />
            <property name="messageListener" ref="myMessageListener" />
        </bean>
    </beans>

第四步：测试代码。

@Test
        public void testQueueConsumer() throws Exception {
            //初始化spring容器
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
            //等待
            System.in.read();
        }
