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》

前言介绍

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。

1、这个案例使用SpringBoot+Netty+WebSocket搭建功能。

2、使用Netty提供的HttpServerCodec、HttpObjectAggregator、ChunkedWriteHandler进行编码解码处理。

3、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。

3.1、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。

3.2、获取个人信息后,就可以知道差异化展示消息到页面。

开发环境

1、jdk1.8【jdk1.7以下只能部分支持netty】

2、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】

3、jquery.min.js、jquery.serialize-object.min.js
