补充一下，spring 集成activeMQ：

1.首先安装MQ和配置环境变量

见下图：

2.1 配置maven ：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>jms8</groupId>
	<artifactId>jms8</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>war</packaging>
	<name />
	<description />
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>
	<dependencies>

		<dependency>
			<groupId>javax.jms</groupId>
			<artifactId>jms</artifactId>
			<version>1.1</version>
		</dependency>
		<dependency>
			<groupId>org.apache.activemq</groupId>
			<artifactId>activemq-core</artifactId>
			<version>5.7.0</version>
		</dependency>
		<dependency>
			<groupId>org.apache.activemq</groupId>
			<artifactId>activemq-pool</artifactId>
			<version>5.7.0</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jms</artifactId>
			<version>3.0.7.RELEASE</version>
		</dependency>
	</dependencies>
	<build>
		<sourceDirectory>${basedir}/src</sourceDirectory>
		<outputDirectory>${basedir}/WebRoot/WEB-INF/classes</outputDirectory>
		<resources>
			<resource>
				<directory>${basedir}/src</directory>
				<excludes>
					<exclude>**/*.java</exclude>
				</excludes>
			</resource>
		</resources>
		<plugins>
			<plugin>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<webappDirectory>${basedir}/WebRoot</webappDirectory>
					<warSourceDirectory>${basedir}/WebRoot</warSourceDirectory>
				</configuration>
			</plugin>
			<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>1.6</source>
					<target>1.6</target>
				</configuration>
			</plugin>
		</plugins>
		<defaultGoal>compile</defaultGoal>
	</build>
</project>

2.配置属性文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd 
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-2.5.xsd"
	default-autowire="byName">


	<!-- 配置connectionFactory -->
	<bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory"
		destroy-method="stop">
		<property name="connectionFactory">
			<bean class="org.apache.activemq.ActiveMQConnectionFactory">
				<property name="brokerURL">
					<value>tcp://127.0.0.1:61616</value>
				</property>
			</bean>
		</property>
		<property name="maxConnections" value="100"></property>
	</bean>

	<!-- Spring JMS Template -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
		<property name="connectionFactory">
			<ref local="jmsFactory" />
		</property>
		<property name="defaultDestinationName" value="subject" />
		<!-- 区别它采用的模式为false是p2p，为true是订阅 -->
		<property name="pubSubDomain" value="true" />
		<property name="messageConverter" ref="myConvert"></property>
	</bean>

	<!-- 发送消息的目的地（一个队列） -->
	<bean id="destination" class="org.apache.activemq.command.ActiveMQTopic">
		<!-- 设置消息队列的名字 -->
		<constructor-arg index="0" value="subject" />
	</bean>
	
    <!-- 消息监听  -->  
    <bean id="listenerContainer"  
        class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <!-- 消息监听器输出消息的数量 -->  
        <property name="concurrentConsumers" value="1" />  
        <property name="connectionFactory" ref="jmsFactory" />  
        <property name="destinationName" value="subject" />  
        <property name="messageListener" ref="myMessageListener" />  
        <property name="pubSubNoLocal" value="false"></property>  
    </bean> 
     
	<!-- 消息转换器 -->
	<bean id="myConvert" class="com.acca.activemq.convert.MyConvert">
	</bean>

   <!-- 消息侦听器 -->
   <bean id="myMessageListener" class="com.acca.activemq.listener.MyMessageListener"></bean>

   <!-- 
	<bean id="messageReceiver" class="com.acca.activemq.ProxyJMSConsumer">
		<property name="jmsTemplate" ref="jmsTemplate"></property>
		<property name="destination" ref="destination"></property>
	</bean>
	-->

    

</beans>

3.写一个发送者：

 public static void main(String[] args) {
        
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");

        JmsTemplate template = (JmsTemplate) applicationContext.getBean("jmsTemplate");
        User user=new User();
        user.setUserName("张三");
        template.convertAndSend(user);
        System.out.println("成功发送了一条JMS消息");

    }

4.写一个转换器：

public class MyConvert implements MessageConverter {

    /**
     * @param arg0
     * @return
     * @throws JMSException
     * @throws MessageConversionException
     * @see org.springframework.jms.support.converter.MessageConverter#fromMessage(javax.jms.Message)
     */
    public Object fromMessage(Message message) throws JMSException, MessageConversionException {
        User user=null;
            if(message instanceof ActiveMQObjectMessage){
                ActiveMQObjectMessage aMsg = (ActiveMQObjectMessage) message; 
                 user=(User) aMsg.getObject();
            }
        return user;
    }

    /**
     * @param arg0
     * @param arg1
     * @return
     * @throws JMSException
     * @throws MessageConversionException
     * @see org.springframework.jms.support.converter.MessageConverter#toMessage(java.lang.Object, javax.jms.Session)
     */
    public Message toMessage(Object object, Session session) throws JMSException,
        MessageConversionException {
        
        ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session.createObjectMessage();
        msg.setObject((Serializable) object);
        return msg; 
    }

}

5.消息监听者：

public class MyMessageListener implements MessageListener {

    /**
     * @param arg0
     * @see javax.jms.MessageListener#onMessage(javax.jms.Message)
     */
    public void onMessage(Message message) {
       System.out.println(message.toString());
       System.out.println("MyMessageListener");
       if(message instanceof ObjectMessage){
           ObjectMessage objectMessage=(ObjectMessage) message;
           try {
            User user=(User) objectMessage.getObject();
            System.out.println(user.getUserName());
        } catch (JMSException e) {
            e.printStackTrace();
        }
       }
    }

}

7.效果：
