[网络协议]使用grpc写一个rpc调用组件（一）

既然使用grpc,那么我们不可能每次都生成服务，所以我们先生成一些公共服务，并通过Any来实现自定义化

proto文件：

orange_grpc_metadata.proto:

syntax = "proto3";

option java_package = "com.orange.grpc.proto.auto";
option java_outer_classname = "MetaData";

message Metadata{
    string type = 3 ;
    string client = 8 ;
    map<string,string> headers = 7;
}

orange_grpc_restload.proto

syntax = "proto3";
import "google/protobuf/any.proto";
import "orange_grpc_metadata.proto";

option java_package = "com.orange.grpc.proto.auto";
option java_outer_classname = "RestLoad";

message Restload{
    Metadata metadata = 2;
    google.protobuf.Any body = 3;
}

orange_grpc_service.proto

syntax = "proto3";
import "orange_grpc_restload.proto";

option java_package = "com.orange.grpc.proto.auto";

service RequestStream{
    rpc requestStream (Restload) returns (stream Restload);
}

service Request {
    rpc request (Restload) returns (Restload);
}

service BiRequestStream{
    rpc requestBiStream (stream Restload) returns (stream Restload) ;
}

完成后进程构建，然后将生成的java文件拷贝到包目录
