一、依赖配置引入
1. 引入SpringBoot整合RabbitMQ依赖
<!--springboot整合RabbitMQ依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency>
2. 生产者配置文件
#RabbitMQ 连接信息
spring:rabbitmq:addresses: 127.0.0.1port: 5672username: adminpassword: admin#虚拟主机virtual-host: /admin#连接超时时间connection-timeout: 15000##开启 confirm 确认机制#发送确认 对应RabbitTemplate.ConfirmCallback接口#消息发送成功 有2个重要参数# ack 状态为true correlationId 全局唯一ID用于标识每一支队列publisher-confirms: true#开启 return 确认机制publisher-returns: true#设置为 true 后 消费者在消息没有被路由到合适队列情况下会被return监听，而不会自动删除#发送失败回退，对应RabbitTemplate.ReturnCallback接口template:mandatory: true
3. 主配置
package com.gblfy.springboot.config;import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;@Configuration
@ComponentScan({"com.gblfy.springboot.*"})
public class MainConfig {
}
二、代码Conding

}2.2. 实体对象
