mina的编码和解码以及断包的处理,发送自定义协议,仿qq聊天,发送xml或json

最近一段时间以来，mina很火，和移动开发一样，异常的火爆。前面写了几篇移动开发的文章，都还不错，你们的鼓励就是我最大的动力。好了，废话少说。我们来看下tcp通讯吧。
tcp通讯对于java来说是很简单的。就是socket，也就是大家常说的套接字。大家不要把它看的很难。说白了tcp通讯其实就是数据流的读写。一条输入流，一条输出流。分别复杂发消息和接收消息。
明白了这些，ok，我们来看看我写的例子吧。先看服务器端的测试类的源码：

package com.minaqq.test;import com.minaqq.server.ServerMsgProtocol;import com.minaqq.worker.ServerSendMsgThread;public class MsgServerTest {public static void main(String[] args) {if(ServerMsgProtocol.serverStart()){System.out.println("服务器启动成功......");ServerSendMsgThread ssmt=new ServerSendMsgThread();ssmt.start();System.out.println("工作线程启动成功......");}}}
