Here is the dubbo service implementation, a standard impl without any annotations.

public class GreeterServiceImpl implements GreeterService {

    @Override
    public HelloReply sayHello(HelloRequest request) {
        return HelloReply.newBuilder()
                .setMessage("Hello " + request.getName())
                .build();
    }

    @Override
    public CompletableFuture<String> sayHelloAsync(String name) {
        return CompletableFuture.supplyAsync(() -> name);
    }
}
