启动zookeeper，启动provider，启动consumer之后，访问报错。
There was an unexpected error (type=Internal Server Error, status=500).
No provider available from registry 127.0.0.1:2181 for service com.example.interfaceapi.PeopleService on consumer 172.18.71.53 use dubbo version 2.6.2, please check status of providers(disabled, not registered or in blacklist).
定位问题：
查看zookeeper中注册节点，命令：
./zkCli.sh -server 127.0.0.1:2181
查询zookeeper中注册情况，发现provider没有注册进来。
启动provider，在日志中找到

发现service注入失败
发现provider中的@service标签是：
import org.springframework.stereotype.Service;
dubbo中按照https://dubbo.apache.org/zh-cn/blog/dubbo-annotation-driven.html文档，应该导入的是：
import com.alibaba.dubbo.config.annotation.Service;
重新启动服务，日志正常
zookeeper中校验正常：
provider成功注册
