ActiveMQ 整合 Spring 发送和接收消息

1.配置环境
     第一步：引用相关的jar包。

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

     第二步：配置Activemq整合spring。配置ConnectionFactory

<?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"> 
<!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://192.168.25.168:61616" />
</bean>
<!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
<bean id="connectionFactory"
class="org.springframework.jms.connection.SingleConnectionFactory">
<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
<property name="targetConnectionFactory" ref="targetConnectionFactory" />
</bean>
</beans>

     第三步：配置生产者。
     第四步：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
dbbe
: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"> 
<!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://192.168.25.168:61616" />
</bean>
<!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
<bean id="connectionFactory"
class="org.springframework.jms.connection.SingleConnectionFactory">
<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
<property name="targetConnectionFactory" ref="targetConnectionFactory" />
</bean>
<!-- 配置生产者 -->
<!-- Spring提供的JMS工具类，它可以进行消息发送、接收等 -->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
<property name="connectionFactory" ref="connectionFactory" />
</bean>
<!--这个是队列目的地，点对点的 -->
<bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg>
<value>spring-queue</value>
</constructor-arg>
</bean>
<!--这个是主题目的地，一对多的 -->
<bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
<constructor-arg value="topic" />
</bean>
</beans>

     第五步：代码测试

@Test

public void testSpringActiveMq() throws Exception {
//初始化spring容器
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
//从spring容器中获得JmsTemplate对象
JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class);
//从spring容器中取Destination对象
Destination destination = (Destination) applicationContext.getBean("queueDestination");
//使用JmsTemplate对象发送消息。
jmsTemplate.send(destination, new MessageCreator() {

@Override
public Message createMessage(Session session) throws JMSException {
//创建一个消息对象并返回
TextMessage textMessage = session.createTextMessage("spring activemq queue message");
return textMessage;
}
});
}

2.发送消息
     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;
}
});
}

3.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"> 
<!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://192.168.25.168:61616" />
</bean>
<!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
<bean id="connectionFactory"
class="org.springframework.jms.connection.SingleConnectionFactory">
<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
<property name="targetConnectionFactory" ref="targetConnectionFactory" />
</bean>
<!--这个是队列目的地，点对点的 -->
<bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg>
<value>spring-queue</value>
</constructor-arg>
</bean>
<!--这个是主题目的地，一对多的 -->
<bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
<constructor-arg value="topic" />
</bean>
<!-- 接收消息 -->
<!-- 配置监听器 -->
<bean id="myMessageListener" class="cn.e3mall.search.listener.MyMessageListener" />
<!-- 消息监听容器 -->
<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();
}
