Spring整合ActiveMQ消息中间件

在上一篇我们介绍了ActiveMQ的两种模式下消息的发送与接收，现在我们来与spring进行整合

Spring框架整合ActiveMQ

首先，我们创建一个maven项目。我们要整合spring肯定要导入相关依赖，这里我们贴出这个项目完整的依赖：

<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">

        <version>1.0version>

    dependencies>

接下来，我们将创建一个common.xml配置文件来配置我们连接ActiveMQ的连接信息，这样避免我们重复编写代码：
common.xml

<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.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
    <context:annotation-config/>
    
    <bean id="targetConnectionFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://127.0.0.1:61616"/>
    bean>
    
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    bean>
    
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="queue"/>
    bean>
    
    <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="topic"/>
    bean>
beans>

这里 ，我们来创建一个ProducerServer接口

public interface ProductorServer {
    void SendMessage(String message);
}

接下来是它的一个实现类

import javax.annotation.Resource;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
import javax.jms.TextMessage;

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

public class ProductorServerImpl implements ProductorServer{
    @Autowired
    JmsTemplate jmsTemplate;
    //队列模式
//  @Resource(name="queueDestination")  //因为我们可能在spring容器中注入多个目的地，所以这里使用@Resource注解
    //主题模式，消费者和订阅者
    @Resource(name="topicDestination")
    Destination destination;
    public void SendMessage(final String message) {
        //使用JmsTemplate发送消息
        jmsTemplate.send(destination, new MessageCreator() {
            //创建一个消息
            public Message createMessage(Session session) throws JMSException {
                TextMessage textMessage=session.createTextMessage(message);
                return textMessage;
            }
        });
        System.out.println("发送消息:"+message);
    }
}

接着我们来编写配置文件：producer.xml

<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.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
    <import resource="common.xml"/>
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
    bean>
    <bean class="cn.shinelon.jms.ProductorServerImpl"/>
beans> 

现在我们可以测试我们的生产者了：

public class AppProducer {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext("productor.xml");
        ProductorServer server=context.getBean(ProductorServer.class);
        for(int i=0;i<100;i++) {
            server.SendMessage("test"+i);
        }
        context.close();
    }
}

运行上面的代码，我们可以在ActiveMQ服务器上看到100消息，这是没哟消费者，我们下面来创建消费者：

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

public class JmsMessageListener implements MessageListener{
    public void onMessage(Message message) {
        TextMessage textMessage=(TextMessage) message;
        try {
            System.out.println(textMessage.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

consumer.xml配置文件

<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.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
    
    <import resource="common.xml"/>
    
    <bean id="JmsMessageListener" class="cn.shinelon.MessageListener.JmsMessageListener"/>
    
    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory"/>
        
        
        <property name="destination" ref="topicDestination"/>

        <property name="messageListener" ref="JmsMessageListener"/>
    bean>
beans>

下面我们来加载我们的消费者并且启动就会返现100条消息被全部消费

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

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

至此，Spring和ActiveMQ整合完毕。
