Dubbo入门 服务方报错 Error creating bean with name "" defined

实现类

import com.alibaba.dubbo.config.annotation.Service;
import service.HelloService;

@Service
public class HelloServiceImpl implements HelloService {

    @Override
    public String sayHello(String name) {
        return "Hello," + name + "!!!";
    }
}
