在windows上使用protobuf

Posted 2020-12-20

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:work2020protoprotoc-3.13.0-win64inprotoc.exe --plugin=protoc-gen-grpc-java=D:work2020protoprotoc-gen-grpc-java-1.28.1-windows-x86_64.exe --grpc-java_out=. helloworld.proto
获得：GreeterGrpc
2）D:work2020protoprotoc-3.13.0-win64inprotoc.exe --java_out=. helloworld.proto
获得：
HelloReply
HelloReplyOrBuilder
HelloRequest
HelloRequestOrBuilder
HelloWorldProto
