application.yml

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

#自定义队列名称
my_queue: springboot-queue
server:
  port: 8080

config类

package com.vhukze.config;

import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

import javax.jms.Queue;
import javax.jms.Topic;


@Component
public class ConfigQueue {

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

    //首先将队列注入到springboot容器中
    @Bean
    public Queue queue(){
        return new ActiveMQQueue(myQueue);
    }

//    //首先将主题注入到springboot容器中
//    @Bean
//    public Topic topic(){
//        return new ActiveMQTopic(myQueue);
//    }
}

生产者类

package com.vhukze.producer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import javax.jms.Queue;
import javax.jms.Topic;

@Component
public class P2pProducer {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue queue;

//    @Autowired
//    private Topic topic;

    //每隔五秒向队列发送消息
    @Scheduled(fixedDelay = 5000)
    public void send(){
        String msg = System.currentTimeMillis() + "";
        jmsMessagingTemplate.convertAndSend(queue,msg);
//        jmsMessagingTemplate.convertAndSend(topic,str);
        System.out.println("采用点对点模式发送消息"+msg);
    }
}

注意：在启动类添加开启定时任务 

@EnableScheduling

 

消费者

依赖依然是上面的那些

配置文件把端口号改了，8080生产者用了

消费者类

package com.vhukze.consumer;

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

@Component
public class P2pConsumer {

    //使用此注解即可监听指定名称的队列
    @JmsListener(destination = "${my_queue}")
    public void recive(String msg){

        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);
    }

}

这是点对点模式，发布订阅模式只需要把代码中注释打开，换了Queue的即可

然后在配置文件中添加开启发布订阅模式
