### 操作步骤 ###

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，负责监听  
第三步：配置MessageListener监听器  
第四步：初始化Spring容器，进行监听

### 添加jar包 ###

<dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-all</artifactId>
    </dependency>

### 创建监听器 ###

创建MessageListener对象  
用于接收消息

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

### 配置监听器 ###

配置MessageListener  
添加配置文件  
applicationContext-activemq.xml

<?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">
            <constructor-arg name="brokerURL" value="tcp://192.168.25.168:61616"/>
        </bean>
        
        <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
            <property name="targetConnectionFactory" ref="targetConnectionFactory"></property>
        </bean>
        
        <bean id="test-queue" class="org.apache.activemq.command.ActiveMQQueue">
            <constructor-arg name="name" value="test-queue"></constructor-arg>
        </bean>
        <bean id="itemAddTopic" class="org.apache.activemq.command.ActiveMQTopic">
            <constructor-arg name="name" value="item-add-topic"></constructor-arg>
        </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="test-queue" />
            <property name="messageListener" ref="myMessageListener" />
        </bean>
    </beans>

### 加载配置文件 ###

初始化Spring容器  
进行监听

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