Thrift框架入门使用及原理（学习之路）

Thrift框架入门使用及原理

下载thrift.exe文件
下载地址：http://archive.apache.org/dist/thrift/0.9.3/
下载完成后，把文件名改成thrift.exe（切记）
增加环境变量
在path中增加以下环境变量：

测试安装thrift是否成功
在cmd中输入以下，测试成功！

编写.thrift文件

service HelloService {
	string sayHello (1: string name);
}

在.thrift文件目录下打开命令行，输入如下命令生成代码
thrift --gen java myThrift.thrift
生成代码如下：
