mina HTTP协议实例 minaHttp编码解码器

minaHTTP请求实例
有的时候我们需要高性能的响应服务，而传统的webService方式，tomcat_Web服务器不能满足我们的要求时，mina是一个很好的选择（netty也很不错）,正是因其快速的处理能力，备受游戏开发者的喜爱、有高性能要求的接口开发者喜爱，本文给出一个mina的HTTP服务实例，编码解码都已写好，可直接测试。

只给出了以部分代码，详细代码请在附件中下载

测试方法.
启动HttpServer.java服务端

浏览器中输入：
//http://127.0.0.1:8882/execute.do?method=hello&user=eric&pwd=123321&age=23

//服务端输出结果：

2015-09-29 22:34:38  sessionCreated...2015-09-29 10:34:38
2015-09-29 22:34:38  sessionOpened...2015-09-29 10:34:38
context...execute.do
method====hello
user====eric
pwd====123321
age====23
user parameters====1----eric
2015-09-29 22:34:38  sessionClosed...2015-09-29 10:34:38
2015-09-29 22:34:38  messageSent...2015-09-29 10:34:38
//浏览器上显示的响应内容：
