没有版本号，表示springboot已经整合好了

项目结构：

![324564c35f89102ca8a964b23d524f65.png][]

yml：

spring:
      activemq:
        broker-url: tcp://192.168.91.6:61616
        user: admin
        password: admin
    my_queue: springboot-queue-toov5
    server:
      port: 8080

config：

package com.toov5.config;
    
    import javax.jms.Queue;
    
    import org.apache.activemq.command.ActiveMQQueue;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.stereotype.Component;
    
    @Component
    public class ConfigQueue {
       @Value("${my_queue}")
       private String myQueue;
        
        //首先将队列注入到SpringBoot容器中去
        @Bean
        public Queue queue() {
            return new ActiveMQQueue(myQueue); 
        } 
        
    }

producer

package com.toov5.Producer;
    
    import javax.jms.Queue;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.core.JmsMessagingTemplate;
    import org.springframework.scheduling.annotation.Scheduled;
    import org.springframework.stereotype.Component;
    
    @Component
    public class P2PProducer {
        @Autowired
        private JmsMessagingTemplate jmsMessagingTemplate;
        //把队列注入进来 
        @Autowired  //此注解默认是以类型找  在配置文件中 已经注入的  @Bean 
        private Queue queue;
        
        //每隔5s时间向队列发送消息
        @Scheduled(fixedDelay=5000)  //每间隔2s向队列发送消息
        public void send() {
            String msgString = System.currentTimeMillis()+" ";
            jmsMessagingTemplate.convertAndSend(queue,msgString);
            System.out.println("点对点通讯，msg"+msgString);
        }
    }

启动类：

package com.toov5;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.scheduling.annotation.EnableScheduling;
    
    @SpringBootApplication
    @EnableScheduling  //开启定时任务
    public class AppProducer {
       public static void main(String[] args) {
        SpringApplication.run(AppProducer.class, args);
    }
    }

运行：

一直在增加

**思路总结： queue 注入到springboot容器， 然后producer 去取出来 spring定时任务 5s定时写入消息**

然后创建另外一个Consumer 的maven 项目：

        public void receiver(String msg) {
            System.out.println("消费者成功获取到生产者的消息，msg"+msg);
        }
        
        
    }

            SpringApplication.run(AppConsumer.class, args);
        }
        
    }

修改为两个不同的端口一起跑：
