一、下载protoc.exe 二、下载protoc-gen-grpc-java-1.28.1-windows-x86_64.exe 三、编写helloworld.proto文件 内容： syntax = "proto3";
option java_multiple_files = true; option java_package = "com.yuhang.protobuf"; option java_outer_classname = "HelloWorldProto"; option objc_class_prefix = "HLW";
package helloworld;
// The greeting service definition. service Greeter { // Sends a greeting rpc SayHello (HelloRequest) returns (HelloReply) {} }
// The request message containing the user's name. message HelloRequest { string name = 1; }
// The response message containing the greetings message HelloReply { string message = 1; } 四、在cmd执行以下命令 1）D:\work2020\proto\protoc-3.13.0-win64\bin\protoc.exe --plugin=protoc-gen-grpc-java=D:\work2020\proto\protoc-gen-grpc-java-1.28.1-windows-x86_64.exe --grpc-java_out=. helloworld.proto 获得：GreeterGrpc 2）D:\work2020\proto\protoc-3.13.0-win64\bin\protoc.exe --java_out=. helloworld.proto 获得： HelloReply HelloReplyOrBuilder HelloRequest HelloRequestOrBuilder HelloWorldProto 五、工具地址 protoc-3.13.0-win64：https://down.51cto.com/data/2468704 protoc-gen-grpc-java-1.28.1-windows ：https://down.51cto.com/data/2468703
