idea 生成 protobuf

1.插件搜索“protobuf Support”，安装，重启

2.pom文件添加：

<properties>
        <protobuf.version>3.5.1</protobuf.version>
        <protobuf-java-format.version>1.2</protobuf-java-format.version>
        <grpc.version>1.11.0</grpc.version>
</properties>

3.在项目src/main/proto/路径下添加需要的.proto文件

4.运行插件：

5.生成文件：
