Spring + ActiveMQ实现生产者消费者模式和发布订阅模式

环境准备

  1. 安装最新版ActiveMQ
  2. Jdk1.8
  3. Spring

创建工程

通过gradle构建项目

引入依赖包

在build.gradle文件中加入以下依赖

RESTful Api接口

QueueActiveApi

package api;

import java.text.MessageFormat;

import javax.ws.rs.Consumes;

import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;

import service.SendQueueMessage;

@Path("active")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class QueueActiveApi {

    private final Logger log = Logger.getLogger(getClass());
    private final int counts=10;
    @Autowired
    private SendQueueMessage sendMessage;
    @POST
    @Path("/queue")
    public Response setSmsActiveQueue() {
        log.info("队列模式--开始发送消息");
        System.out.println("队列模式--开始发送消息");
        for (int i = 1; i < counts; i++) {
            String message=MessageFormat.format("我是第{0}条消息", i);
            log.info(message);
            sendMessage.doSendAction(message);
        }
        return Response.ok().build();
    }
}

TopicActiveApi

package api;

import java.text.MessageFormat;

import javax.ws.rs.Consumes;

import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import service.SendQueueMessage;
import service.SendTopicMessage;

@Path("active")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class TopicActiveApi {

    private final Logger log = Logger.getLogger(getClass());
    private final int counts=10;
    @Autowired
    private SendTopicMessage sendMessage;
    @POST
    @Path("/topic")
    public Response setSmsActiveTopic() {
        log.info("订阅模式--开始发送消息");
        System.out.println("订阅模式--开始发送消息");
        for (int i = 1; i < counts; i++) {
            String message=MessageFormat.format("我是第{0}条消息", i);
            sendMessage.doSendAction(message);
        }
        return Response.ok().build();
    }
}

发送消息

SendQueueMessage

package service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;

@Service
public class SendQueueMessage {

    @Autowired
    @Qualifier("jmsQueueTemplate")
    private JmsTemplate jmsQueueTemplate;

    public void doSendAction(String message) {
        jmsQueueTemplate.convertAndSend("test.queue",message);
    }
}

SendTopicMessage

package service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;

@Service
public class SendTopicMessage {

    @Autowired
    @Qualifier("jmsTopicTemplate")
    private JmsTemplate jmsTopicTemplate;

    public void doSendAction(String message) {
        jmsTopicTemplate.convertAndSend("test.topic", message);
    }


}

消息监听者

Point-to-Point模式实现两个消费者

queueReceiver1

package listener.queue;

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

import org.springframework.stereotype.Component;
@Component
public class queueReceiver1 implements MessageListener{

    @Override
    public void onMessage(Message message) {
        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("QueueReceiver1接收到消息:"+tm.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }

    }

}

queueReceiver2

package listener.queue;

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

import org.springframework.stereotype.Component;
@Component
public class queueReceiver2 implements MessageListener{

    @Override
    public void onMessage(Message message) {
        TextMessage textMessage=(TextMessage) message;
        try {
            System.out.println("QueueReceiver2接收到消息:"+textMessage.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }

    }

}

Pub-Sub模式实现两个订阅者

topicReceiver1

package listener.topic;

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

import org.springframework.stereotype.Component;

@Component
public class topicReceiver1 implements MessageListener{

    @Override
    public void onMessage(Message message) {
        try {
            System.out.println("TopicReceiver1接收到消息:"+((TextMessage)message).getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

}

topicReceiver2

package listener.topic;

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

import org.springframework.stereotype.Component;

@Component
public class topicReceiver2 implements MessageListener{

    @Override
    public void onMessage(Message message) {
        try {
            System.out.println("TopicReceiver1接收到消息:"+((TextMessage)message).getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

}

运行结果

  1. 对于Point-to-Point模式，一条消息只会被一个消费者消费
  2. 对于Pub-Sub模式，一条消息会被所有订阅者消费
