win10+google protobuffer +IDEA的配置

一、下载google-protoc for win的zip包（https://github.com/protocolbuffers/protobuf）

二、配置环境标量，在CMD里使用protoc --version查看

三、在IDEA里安装protobuf support插件

四、在工程的main目录下新建一个文件夹，用来存放.proto的文件。然后把该文件夹Mark directory as sources root

参考：window下配置protobuf在IDEA上开发java项目（https://www.jianshu.com/p/cf788d366f67）

五、我的pom.xml:

还有其他方法，参照：使用Maven插件整合protocol buffer（https://blog.csdn.net/qq_27273089/article/details/70230897）

六、选择protobuf:compile

七、生成的文件在target/generated-sources/protobuf/java/包名下

(或者在控制台输入：protoc --java_out=src/main/java src/main/proto/student.proto
)
