设想有如下场景：若干的客户端与服务器端建立连接，建立连接后，服务器端随机发送字符串给客户端，客户端打印输出。该节案例使用TCP编程。

简言： 首先我们得先弄清楚websocket和tcpSocket的区别。websocket也是基于tcp的应用层协议，只是在传统的socket上进行了封装。...ChannelActiveHandle()); pipeline.addLast("socketChoose",new SocketChooseHandle()); //tcpsocket...反之，如果是tcpsocket连接，会直接走tcpSocketHandle处理。这里我们用的LengthFieldBasedFrameDecoder长度占包粘包处理器。
