application.yml

server:
  port: 8890

文件：eventInfo.proto

syntax = "proto3";

option java_multiple_files = true;
option java_package = "com.event.proto";//生成代码的位置

service EventInfoService {
  rpc sendMessageEvent(EventInfoMessage) returns (EventInfoResponse) {}
}

message EventInfoMessage {
  string msg = 1;
}


message EventInfoResponse {
  int32 code = 1;
  string msg = 2;
  bool success = 3;
}

GrpcService

@GrpcService
public class EventInfoServiceGrpcImpl extends EventInfoServiceGrpc.EventInfoServiceImplBase {

    @Override
    public void sendMessageEvent(EventInfoMessage request, StreamObserver responseObserver) {
        EventInfoResponse.Builder eventInfo = EventInfoResponse.newBuilder();
        //业务处理
        String msg = request.getMsg();
        //
        if ("success".equals(msg)){
            eventInfo.setCode(200).setMsg("success"+100000).setSuccess(true);
        }else{
            eventInfo.setCode(500).setMsg("error"+100000).setSuccess(false);

        }
        responseObserver.onNext(eventInfo.build());
        responseObserver.onCompleted();
    }

}

按照下面操作去点击：

 生成的java 代码复制一份放到 客户端的代码包里。

代码结构：

proto : 放的是需要生成Java 文件的基础  .proto文件

客户端

 proto-client 服务配置
