SpringBoot+RabbitMQ收发消息

首先下面两个博客安装rabbitmq所需环境和软件

参考文档：

1. window下安装ErLang环境
2. window下安装rabbitmq

创建springboot项目，引入依赖

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

mq上创建队列

项目结构

增加配置

spring:
    rabbitmq:
        username: guest
        password: guest
        # 默认端口
        port: 5672
        host: 127.0.0.1

创建配置类

package com.example.mqdemo.conf;

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;

/**
 * mq配置类
 *
 * @Version 0.0.1
 * @Date 2022/4/11 10:40
 */
public class RabbitConfig{
    @Bean
    public Queue helloQueue() {
    	//mq上队列名称对应
        return new Queue("test");
    }
}

创建收发信息处理类

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 *
 * @Version 0.0.1
 * @Date 2022/4/11 10:42
 */
@RestController
public class TestController {
    
    @Autowired
    RabbitTemplate rabbitTemplate;
    
    @GetMapping("/send")
    public void send() {
        String context = "需要发送的内容";
        rabbitTemplate.convertAndSend("test", context);
    }
    @RabbitListener(queues = "test")
    public void receiveMessageTest(String test) {
        // test则是接收的内容
        System.out.println(test);
    }
}

测试 请求或调用send方法即可
