ActiveMQ 整合 spring

一、添加 jar 包

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-all</artifactId>
    <version>5.11.2</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jms</artifactId>
    <version>4.2.4.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>4.2.4.RELEASE</version>
</dependency>

二、发送消息层 ：applicationContext-activemq.xml

<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://192.168.25.129:61616" />
    </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><!--根据业务修改名称-->
        </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" /><!--根据业务修改名称-->
    </bean>
    
</beans>

三、发送消息

/**
 * 点到点形式发送消息
 * @throws Exception
 */
@Test
public void sendMessage() throws Exception{
    //初始化 spring 容器
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
    //从容器中获得 JMsTemplate 对象
    JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class);
    //从容器中获得一个 Destination 对象
    Destination destination = (Destination) applicationContext.getBean("queueDestination");
    //发送消息
    jmsTemplate.send(destination, new MessageCreator() {
        
        @Override
        public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage("send avtivemq message");
        }
    });
}

实际工作中怎么注入呢 。( @Autowired 通过类型注入；@Resource 默认先通过 id 注入，如果没有 id，再通过类型注入 )

@Autowired
Private JmsTemplate jmsTemplate ;
@Resource
Private Destination topicDestination ; //默认在配置文件的 <bean> 中找 id 为 topicDestination 的。如果没有，再去找类型为 Destination  的<bean>

四、接收消息

1、新建一个类 MyMessageLister ( 根据自己业务，命名这个类，注意配置文件对应起来 )，用来监听接收消息

package com.fw.search.message;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

public class MyMessageLister implements MessageListener{

    @Override
    public void onMessage(Message message) {
        //取消息内容
        TextMessage textMessage = (TextMessage) message;
        
        try {
            String text = textMessage.getText();
            System.out.println(text);
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

2、接收消息层：applicationContext-activemq.xml

<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://192.168.25.129:61616" />
    </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="com.fw.search.message.MyMessageLister" />
    <!-- 消息监听容器 -->
    <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destination" ref="queueDestination" /><!-- 这里可以配置点对点或者广播 -->
        <property name="messageListener" ref="myMessageListener" />
    </bean>
    
</beans>

3、怎么接收消息

　　初始化这个 spring ( applicationContext-activemq.xml ) 容器就可以了

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