Apache MINA(Multipurpose Infrastructure for Network Applications) 是 Apache 组织一个较新的项目，它为开发高性能和高可用性的网络应用程序提供了非常便利的框架。当前发行的 MINA 版本支持基于 Java NIO 技术的 TCP/UDP 应用程序开发、串口通讯程序（只在最新的预览版中提供），MINA 所支持的功能也在进一步的扩展中。

新项目里的web service需要高并发服务能力，tomcat目前最多支持到200个并发。远达不到要求。

0.测试环境：

client和server:CPU：单核2G，内存:4GB;

网络:局域网

1.下载mina2.0安装包
http://labs.renren.com/apache-mirror//mina/2.0.4/apache-mina-2.0.4-bin.tar.gz
http://mina.apache.org/downloads.html
2.解压后
打开eclipse建立工程HelloServer，把mina-core-2.0.4.jar,mina-filter-compression-2.0.4.jar
,slf4j-api-1.6.1.jar导入,注意java必须要1.5以上
3.写代码

也可按照官方例子httpserver http://mina.apache.org/report/trunk/xref/org/apache/mina/example/httpserver/
把代码写好，官方例子是1.x的，我在附件里把例子里的import错误改过来
 
另外为了好测试，把ServerHandler.java改为(粗体那段是我加的)：
 
4.打成jar包
先运行一下工程
点击工程右键->export->Runable jar file->选择“server-HelloServer”（若是没有的话先运行一下工程就有了）->finish
5.测试
把jar上传到linux(192.168.13.120)下
执行：
