hession简单模拟
闲来无事，自己手动写写代码，如有错误不必深究，哈哈……

hession的实现：
1、业务接口
2、业务实现，继承HessianServlet
3、服务端配置HessianServlet
4、客户端调用利用HessianProxyFactory的create方法根据接口创建代理类

我的简单实现：
1、业务接口
2、业务实现类，类中方法最好抛出个Exception，方便客户端接受异常信息
3、服务端配置实现了自己的业务逻辑的servlet，继承自AbstractServiceSrv
4、客户端调用利用ProxyFactory的create方法根据接口创建代理类
5、简单的单点登录

简单模拟hession代理类：
