1. 生产者

1.1 引入maven依赖

1.2 application.yml配置

spring:
  activemq:
  ###MQ连接通讯地址
    broker-url: tcp://127.0.0.1:61616
  ###账号
    user: admin
  ###密码  
    password: admin

#
##自定义队列    
my_queue: springboot2.0-queue

server:
  port: 8089

1.3 创建配置类ConfigQueue

@Component
public class ConfigQueue {

    @Value("${my_queue}")
    private String myQueue;

    /**
     * 1.首先需要将队列注入springboot容器中
     *
     * @return
     */

    @Bean
    public Queue queue() {
        return new ActiveMQQueue(myQueue);
    }

}

1.4 创建生产者类Producer

@Component
public class Producer {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    private Queue queue;

    /**
     * 每隔5秒种时间向队列中发送消息
     */

    @Scheduled(fixedDelay = 5000)
    public void send() {
        String userName = System.currentTimeMillis() + "";
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("userName", userName);
        jsonObject.put("email""apkdream@163.com");
        String msg = jsonObject.toJSONString();
        jmsMessagingTemplate.convertAndSend(queue, msg);
        System.out.println("采用点对点通讯模式,msg:" + msg);
    }
}

1.5 启动类AppProducer

@SpringBootApplication
@EnableScheduling
public class AppProducer {

    public static void main(String[] args) {
        SpringApplication.run(AppProducer.class, args);
    }

}

2. 消费者

2.2 application.yml配置

spring:
  activemq:
  ###MQ连接通讯地址
    broker-url: tcp://127.0.0.1:61616
  ###账号
    user: admin
  ###密码

#
##自定义队列    
my_queue: springboot2.0-queue

server:
  port: 8088

2.3 创建消费者类Consumer

import com.alibaba.fastjson.JSONObject;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;

/**
 * 消费者
 */

@Component
public class Consumer {

    @Autowired
    private JavaMailSender javaMailSender;

    /**
     * 幂等性
     * @param msg
     * @throws Exception
     */

    @JmsListener(destination = "${my_queue}")
    public void receive(String msg) throws Exception {
        if (StringUtils.isEmpty(msg)) {
            return;
        }
        /** 1.解析json **/
        JSONObject parseObject = JSONObject.parseObject(msg);
        String userName = parseObject.getString("userName");
        String email = parseObject.getString("email");
        sendSimpleMail(email, userName);
        System.out.println("采用点对点模式,消费者成功获取到生产者的消息,msg:" + msg);

    }

    public void sendSimpleMail(String eamil, String userName) throws Exception {
        SimpleMailMessage message = new SimpleMailMessage();
        /** 邮件来自 自己发自己 **/
        message.setFrom(eamil);
        /** 发送给谁 **/
        message.setTo(eamil);
        /** 邮件标题 **/
        message.setSubject("niceyoo 新邮件提醒");
        /** 邮件内容 **/
        message.setText("收到一批新的" + userName + "邮件!");
        /** 发送邮件 **/
        javaMailSender.send(message);
        System.out.println("邮件发送完成," + JSONObject.toJSONString(message));
    }

}

2.4 启动类AppConsumer

@SpringBootApplication
public class AppConsumer {

    public static void main(String[] args) {
        SpringApplication.run(AppConsumer.class, args);
    }

}

3. 启动截图

3.1 生产者截图

3.2 消费者截图

3.3 ActiveMQ后台截图

  1. Number Of Consumers 消费者 这个是消费者端的消费者数量 ;
  2. Number Of Pending Messages 等待消费的消息 这个是当前未出队列的数量。可以理解为总接收数-总出队列数;
  3. Messages Enqueued 进入队列的消息 进入队列的总数量,包括出队列的。 这个数量只增不减 ;
  4. Messages Dequeued 出了队列的消息 可以理解为是消费这消费掉的数量 ;

3.4 邮件系统截图
