干货--JMS(java消息服务)整合Spring项目案例

Sprng-jms消息服务小项目

所需的包:
spring的基础包
spring-jms-xx包
spring-message–xx包
commons-collection-xx包
commons-pool2-xx包
aop切面的包: spring-aop,spring-aspect,aopalliance,aspectjrt.jar,aspectjweaver.jar

配置:
1.配置ConnectionFactory
2.配置jmsTemplate;
3.配置Destination

4.配置listener
5.配置container

话不多说，直接上代码
前提是你已经开启了activemq服务
看一下项目架构

这里写图片描述

临听器有两种实现方案: 一种是采用原生的jms的MessageListener
另一种是采用spring的方案:SessionAwareMessageListener
前一种只能消费消息,不能发送回送消息
后一种可以再接到消息后，给生产者回送消息,它自己即是生产者也是消费者
所有所需的连接工、目的地等都是通过Spring注入的,具体看后面的配置文件

发送消息的接口

package com.tg.service;


public interface PersonService {
    public void sendMessage(String message);

}

生产者一

package com.tg.service;

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

import org.springframework.context.annotation.Scope;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;


    @Service("personServiceImpl")
    @Scope("prototype")
    public class PersonServiceImpl implements PersonService {

        private Destination destination;
        private JmsTemplate jsmTemplate;
        private Destination replyQueueDestination;


        @Override
        public void sendMessage(final String message) {
            System.out.println("生产者发送消息"+ message);

            //回调
            jsmTemplate.send(destination, new MessageCreator(){
                @Override
                public Message createMessage(Session session) throws JMSException {
                    //创建一个文本消息
                    Message msg = session.createTextMessage(message);
                    //指定为非持久化方式
                    msg.setJMSDeliveryMode(   DeliveryMode.NON_PERSISTENT   );
                    return msg;
                }
            });
        }

        @Resource(name="queueDestination")
        public void setDestination(Destination destination) {
            this.destination = destination;
        }

        @Resource(name="jmsTemplate")
        public void setJsmTemplate(JmsTemplate jsmTemplate) {
            this.jsmTemplate = jsmTemplate;
        }

        @Resource(name = "replyQueueDestination")
        public void setReplyDestination(Destination replyDestination) {
            this.replyQueueDestination = replyDestination;
        }


}

生产者二

package com.tg.service;

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

import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

@Service("personServiceImpl2")
public class PersonServiceImpl2 implements PersonService {
    private Destination destination;   //用于存发送信息的队列
    private JmsTemplate jsmTemplate;   //jms操作模板
    private Destination replyQueueDestination;   //用于存回复信息的队列,
    @Override
    public void sendMessage(final String message) {
        System.out.println("生产者2->发送消息" + message);
        // 回调
        jsmTemplate.send(destination, new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                Message msg = session.createTextMessage(message);
                // 设置回复的信息的目的地.
                msg.setJMSReplyTo(replyQueueDestination);
                // 设置发送的信息类型 为非持久化信息
                msg.setJMSDeliveryMode(DeliveryMode.NON_PERSISTENT);

                //创建一个消费者，用于接收对方回复的信息   注意，这个消费者临听   replyDestination
                MessageConsumer comsumer2 = session.createConsumer(replyQueueDestination);
                comsumer2.setMessageListener(new MessageListener() {
                    public void onMessage(Message m) {
                        try {
                            System.out.println("接收到的回复信息:" + ((TextMessage) m).getText());
                        } catch (JMSException e) {
                            e.printStackTrace();
                        }
                    }
                });
                return msg;
            }
        });
    }
    @Resource(name = "replyQueueDestination")
    public void setReplyDestination(Destination replyDestination) {
        this.replyQueueDestination = replyDestination;
    }
    @Resource(name = "sendQueueDestination")
    public void setDestination(Destination destination) {
        this.destination = destination;
    }

    @Resource(name = "jmsTemplate")
    public void setJsmTemplate(JmsTemplate jsmTemplate) {
        this.jsmTemplate = jsmTemplate;
    }

}

消费者一

package com.tg.service;

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

//临听器有两种实现方案: 一种是采用原生的jms的MessageListener
//                    另一种是采用spring的方案:SessionAwareMessageListener 

//注意: 这里的MessageListener接口是  jms的接口
public class ConsumerMessageListener1 implements MessageListener {

    @Override
    public void onMessage(Message message) {
        if(  message instanceof TextMessage){
            TextMessage text=(TextMessage) message;
            System.out.println("接收到的消息是一个文本消息:"+ text);

            //这种方式无法回复   所以采用第二种
        }
    }

}

消费者二

package com.tg.service;

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

import org.springframework.jms.listener.SessionAwareMessageListener;
import org.springframework.stereotype.Component;

/**
 * SessionAwareMessageListener：是由spring提供，它可以在回调方法中传入session，以此回送信息到生产者
 * @author Administrator
 *
 */
@Component("consumerMessageListener2")
public class ConsumerMessageListener2 implements SessionAwareMessageListener<TextMessage> {

    private Destination destination;

    @Override
    public void onMessage(TextMessage message, Session session) throws JMSException {
            System.out.println("接收到的消息是一个文本消息:"+ message.getText());
            //通过session 创建  producer对象，再回送信息
            //从message中取出信息回送的目的地,以便创建生产者.
            MessageProducer producer=session.createProducer( message.getJMSReplyTo()   );
            //创建一条消息
            Message textMessage=session.createTextMessage(  "生产者发过来的信息已经处理完毕，game over..."   );   
            //调用发送
            producer.send(textMessage);
    }

    @Resource(name="sendQueueDestination")
    public void setDestination(Destination destination) {
        this.destination = destination;
    }




}

看一下第一种的测试类

package com.tg.test;

import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.context.ApplicationContext;

import com.tg.service.PersonService;

//测试生产者发送了一个消息，消费者接收

//整合spring    http://haohaoxuexi.iteye.com/blog/1893038
public class Test1 {

    public static void main(String[] args) {
        ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
        PersonService ps=(PersonService) ac.getBean("personServiceImpl");
        for( int i=0;i<10;i++){
            Thread t=new Thread(new User(ps,"汤"+i));
            t.start();
        }
    }
}

class User implements Runnable{
    private PersonService ps;
    private String name;
    public User(PersonService ps, String name) {
        super();
        this.ps = ps;
        this.name = name;
    }

    @Override
    public void run() {
        for( int i=0;i<10;i++){
            ps.sendMessage(name+"向你问好");
        }

    }

}
