💎一站式轻松地调用各大LLM模型接口,支持GPT4、智谱、星火、月之暗面及文生图 广告
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源码分析(一)-- 基本概念](http://blog.csdn.net/iter_zc/article/details/39496439) [Thrift源码分析(二)-- 协议和编解码](http://blog.csdn.net/iter_zc/article/details/39497863) [Thrift源码分析(三)-- IDL和生成代码分析](http://blog.csdn.net/iter_zc/article/details/39522531) [Thrift源码分析(四)-- 方法调用模型分析](http://blog.csdn.net/iter_zc/article/details/39692951) [Thrift源码分析(五)-- FrameBuffer类分析](http://blog.csdn.net/iter_zc/article/details/39694129) [Thrift源码分析(六)-- Transport传输层分析](http://blog.csdn.net/iter_zc/article/details/39695187) [Thrift源码分析(七)-- TServer服务器分析](http://blog.csdn.net/iter_zc/article/details/39697401) 下面通过一个实际可以运行的例子来跑一跑Thrift,结束这个主题 ![](https://box.kancloud.cn/2016-02-19_56c6c62be2f7b.jpg) 1. 通过IDL来定义接口:   DemoService.thrift ~~~ namespace java com.thrift.test service DemoService{ string sayHi(1:string name); } ~~~ 2. 根据IDL自动生成代码 ~~~ thrift -r --gen java DemoService.thrift ~~~ 3. 生成的代码供服务器和客户端调用 ~~~ /** * Autogenerated by Thrift Compiler (0.8.0) * * DO NOT EDIT UNLESS YOU ARE SURE THAT YOU KNOW WHAT YOU ARE DOING * @generated */ package com.thrift.test;
