Springboot + netty + rabbitmq + myBatis+mysql流量消峰

0.为什么用消息队列
1.代码文件创建结构
2.pom.xml文件
3.三个配置文件开发和生产环境
4.Rabbitmq 基础配置类 TtlQueueConfig
5.建立netty服务器 + rabbitmq消息生产者
6.建立常规队列的消费者 Consumer
7.建立死信队列的消费者 DeadLetterConsumer
8.建立mapper.xml文件
9.建立mapper文件接口
10.建立接口ProducerController 测试
11.测试接口请求1
12.测试接口请求2
13.网络助手测试NetAssist.exe
14.观察rabbitmq界面管理简单介绍
