从源代码安装protoc可参考文章：https://lobin.iteye.com/blog/2435854

 

例子：

TestIntMessage.proto

syntax = "proto3";
option java_package = "com.grpc.service";

message TestIntRequest {
	//optional
    int32 value = 1;
}

message TestIntResponse {
	//optional
	int32 value = 1;
}

编译

$ protoc --java_out=. TestIntMessage.proto

生成
