Serialization_ProtoBuf包下为客户端和服务端的nettyDemo

#### Client/ReqClient为客户端启动程序
#### Server/ReqServer为服务端启动程序
#### ProtoBuf包下为Protobuf的传输协议文件

Websocket包下为websocket服务端

#### NettyServer为启动程序

wsHtml放在tomcat8下的webapp中即可

#### Client.html为纯websocket聊天demo(不包含protobuf方式)
#### PFClient.html为以protobuf向服务端发送消息
#### 后端的区分协议在Websocket.MyWebSocketServerHandler。java
