前面七篇文章分析了Thrfit的方方面面，看到这里时应该对Thrift有了深入的理解。

Thrift源代码分析（一）-- 基本概念

Thrift源代码分析（二）-- 协议和编解码

Thrift源代码分析（三）-- IDL和生成代码分析

Thrift源代码分析（四）-- 方法调用模型分析

Thrift源代码分析（五）-- FrameBuffer类分析

Thrift源代码分析（六）-- Transport传输层分析

Thrift源代码分析（七）-- TServerserver分析

以下通过一个实际能够执行的样例来跑一跑Thrift，结束这个主题

1. 通过IDL来定义接口:   DemoService.thrift

  1. namespace java com.thrift.test
  2.  
  3. service DemoService{
  4. 	string sayHi(1:string name);
  5. }

2. 依据IDL自己主动生成代码

  1. thrift -r --gen java DemoService.thrift

3. 生成的代码供server和client调用

  1. /**
  2.  * Autogenerated by Thrift Compiler (0.8.0)
  3.  *
  4.  * DO NOT EDIT UNLESS YOU ARE SURE THAT YOU KNOW WHAT YOU ARE DOING
  5.  *  @generated
  6.  */
