gRPC与SpringBoot整合思路和步骤

 grpc-server
 grpc-client 

1. 搭建SpringBoot的开发环境
2. 引入与Grpc相关的内容
    <dependency>
          <groupId>com.suns</groupId>
          <artifactId>rpc-grpc-api</artifactId>
          <version>1.0-SNAPSHOT</version>
     </dependency>
    <dependency>
        <groupId>net.devh</groupId>
        <artifactId>grpc-server-spring-boot-starter</artifactId>
        <version>2.14.0.RELEASE</version>
    </dependency>

@GrpcService
public class HelloServiceImpl extends HelloServiceGrpc.HelloServiceImplBase {
    @Override
    public void hello(HelloProto.HelloRequest request, StreamObserver<HelloProto.HelloResponse> responseObserver) {
        String name = request.getName();
        System.out.println("name is " + name);
        responseObserver.onNext(HelloProto.HelloResponse.newBuilder().setResult("this is result").build());
        responseObserver.onCompleted();
    }
}

// application.yml
spring:
  application:
    name: boot-server
  main:
    web-application-type: none
grpc:
  server:
    port: 9000

   <dependency>
      <groupId>net.devh</groupId>
      <artifactId>grpc-client-spring-boot-starter</artifactId>
      <version>2.14.0.RELEASE</version>
   </dependency>

  1. yml
  grpc:
    client:
      grpc-server:
        address: 'static://127.0.0.1:9000'
        negotiation-type: plaintext
  2. 注入stub
  @GrpcClient("grpc-server")
  private HelloServiceGrpc.HelloServiceBlockingStub stub;
