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

xml配置文件

    <!--1.服务提供方在zookeeper中的“别名”-->
    <dubbo:application name="dubbo-server"/>
    <!--2.注册中心的地址-->

    <!--3.扫描类(将什么包下的类作为服务提供类)-->

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 + "!!!";
    }
}
