nfs-rpc 是一个抽象的高性能的 RPC 框架，基于 mina/netty/grizzly/aio 实现。

• client proxy,so u can call remote just like call local: UserService.getById(id);
• server reflection,so u can intergrate the rpc framework with difference server implemenation,such as spring;
• server direct call,u can implement a specify interface to provide for client call;
• single or multi connections,in most case,single connection is enough,but in some cases,u'll need multi connections;
• connection reuse,so u don't need block user thread to wait for connection;
• synchronize call,rpc always need synchronize call;
• timeout,u cann't wait for server return response forever,so u need timeout policy,especially for online app;
• multi or custom serialize protocol(java/hessian/protobuf);
• custom your protocol.
