spring整合activemq之订阅(topic)

spring整合activemq之订阅

　　(1) 创建订阅生产者子工程(war),引入相关依赖

    <dependencies>
        <!-- activemq -->
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-client</artifactId>
            <version>5.13.4</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>
        <!-- 测试相关依赖 -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
        </dependency>
    </dependencies>

　　(2) 编写配置文件:applicationContext-jms-producer.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:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core"
    xmlns:jms="http://www.springframework.org/schema/jms"
    xsi:schemaLocation="http://www.springframework.org/schema/beans   
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context   
        http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.demo.activemq.producer.service"></context:component-scan>

    <!-- 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://127.0.0.1:61616" />
    </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>

    <!-- 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，订阅的 -->
    <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="activemqDemo_topic" />
    </bean>

</beans>

　　(3) 编写订阅生产者类

package com.demo.activemq.producer.service;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Component;

@Component
public class SpringActivemqTopicProducer {
    @Autowired
    private JmsTemplate jmsTemplate;
    
    @Autowired
    private Destination topicDestination;
    
    /**
     * 发送文本消息
     * @param text
     */
    public void sendTextMessage(final String text){
        jmsTemplate.send(topicDestination, new MessageCreator() {            
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(text);
            }
        });        
    }
}

　　(4) 编写测试类,发送订阅消息

package com.demo.activemq.producer.service;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-jms-producer.xml")
public class SpringActivemqTopicProducerTexst {
    @Autowired
    private SpringActivemqTopicProducer topicProducer;
    
    /**
     * @Description: TODO 发送订阅消息
     * @throws
     */
    @Test
    public void testSend(){
        topicProducer.sendTextMessage("SpringActivemqTopicProducer-订阅");
    }    
}

　　(5) 创建订阅消费者1子工程(war),引入相关依赖

    <dependencies>
        <!-- activemq -->
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-client</artifactId>
            <version>5.13.4</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>
        <!-- 测试相关依赖 -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
        </dependency>
    </dependencies>

　　(6) 编写配置文件:applicationContext-jms-consumer.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:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core"
    xmlns:jms="http://www.springframework.org/schema/jms"
    xsi:schemaLocation="http://www.springframework.org/schema/beans   
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context   
        http://www.springframework.org/schema/context/spring-context.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://127.0.0.1:61616" />
    </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>

    <!-- 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>

    <!-- 我的监听类 -->
    <bean id="myMessageListener" class="com.demo.activemq.customer.service.QueueMessageListener"></bean>
    <!-- 消息监听容器 -->
    <bean
        class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destination" ref="topicDestination" />
        <property name="messageListener" ref="myMessageListener" />
    </bean>

    <!--这个是队列目的地，订阅的 -->
    <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="activemqDemo_topic" />
    </bean>
</beans>

　　(7) 编写订阅消费者类(监听)

package com.demo.activemq.customer.service;

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

public class QueueMessageListener implements MessageListener {
    public void onMessage(Message message) {
        TextMessage textMessage = (TextMessage) message;
        try {
            System.out.println("接收到消息：" + textMessage.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

　　(8) 编写测试类,接收订阅消息

package com.demo.activemq.customer.service;

import java.io.IOException;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-jms-consumer.xml")
public class SpringActivemqTopicCustomerTexst {

    @Test
    public void testQueue(){
        try {
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        }        
    }
}
