2019 08 20 netty案例，netty4.1中级拓展篇五《基于Netty搭建WebSocket，模仿微信聊天页面》
作者：小傅哥
博客：https://bugstack.cn - 原创系列专题
沉淀、分享、成长，让自己和他人都能有所收获！
本章节我们模仿微信聊天页面，开发一个基于Netty搭建WebSocket通信案例。Netty的应用方面非常广；聊天、MQ、RPC、数据等等，在5G到来的时候更加需要大量数据传输，Netty的应用也会更加广阔。
- 这个案例使用SpringBoot+Netty+WebSocket搭建功能。
- 使用Netty提供的HttpServerCodec、HttpObjectAggregator、ChunkedWriteHandler进行编码解码处理。
- 通信逻辑尽可能简化到只了解根本，便于后续个人应用及开发的拓展。
- 客户端链接成功后，向服务端发送请求获取个人信息，也可以拓展为登录请求。
- 获取个人信息后，就可以知道差异化展示消息到页面。
- jdk1.8【jdk1.7以下只能部分支持netty】
- Netty4.1.36.Final【netty3.x 4.x 5每次的变化较大，接口类名也随着变化】
- jquery.min.js、jquery.serialize-object.min.js
