一、安装Erlang与Rabbitmq

安装教程本教程是在centos8下试验的，其实linux系统的都差不多RabbitMQ官方：Messaging that just works — RabbitMQRabbitMQ是开源AMQP实现，服务器端用Erlang语言编写，Python、Ruby、 NET、Java、JMS、c、PHP、action screcrive AMQP (高级消息队列协议)和高级消息队列协议是APP应用层协议的开放标准，是为面向消息的中间件而设计的。消息中间件主要用于组件之间的解耦，其中消息的发送方不需要知道消息使用者的存在，反之_rabbitmq安装https://blog.csdn.net/weixin_44545251/article/details/128216395

二、在springboot中使用rabbitmq

1.导入依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2.编写配置文件

spring：rabbitmq:host: localhostport: 5672username: guestpassword: guest

3.配置一个队列

package com.example.Rabbtimq.config;import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class QueueAndExchangeConfig {@Bean("myFirstQueue")public Queue getFirstQueue(){return new Queue("my-first-queue");}
}

4.编写一个生产者类

package com.example.Rabbtimq.controller;import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("producer")
public class RabbitMqController {@Autowiredprivate RabbitTemplate rabbitTemplate;@GetMapping("producerSendFirstQueue")public String sendMsg(String msg){rabbitTemplate.convertAndSend("my-first-queue",msg);return msg;}}

5.编写一个消费者监听队列中的消息

package com.example.Rabbtimq.controller;import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@Component
public class ConsumerHandler {@RabbitListener(queues = "my-first-queue")public void getFirstQueue(String msg){System.out.println("消费者1："+msg);}
}
