Question

Anyone having any examples or thoughts using gRPC together with Spring Boot?

In server

@GrpcService(GreeterGrpc.class)
public class GrpcServerService extends GreeterGrpc.GreeterImplBase {

    @Override
    public void sayHello(HelloRequest req, StreamObserver responseObserver) {
        HelloReply reply = HelloReply.newBuilder().setMessage("Hello =============> " + req.getName()).build();
        responseObserver.onNext(reply);
        responseObserver.onCompleted();
    }
}

In client

@GrpcClient("gRPC server name")
private Channel serverChannel;

GreeterGrpc.GreeterBlockingStub stub = GreeterGrpc.newBlockingStub(serverChannel);
HelloReply response = stub.sayHello(HelloRequest.newBuilder().setName(name).build());
