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

近期一段时间以来，mina非常火，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。你们的鼓舞就是我最大的动力。好了，废话少说。我们来看下tcp通讯吧。

tcp通讯对于java来说是非常easy的。就是socket，也就是大家常说的套接字。大家不要把它看的非常难。

说白了tcp通讯事实上就是数据流的读写。一条输入流，一条输出流。分别复杂发消息和接收消息。

明确了这些，ok。我们来看看我写的样例吧。

先看服务器端的測试类的源代码：

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......");
		}
	}
}

服务端连接代码：
