## Ask your question here
环境：
springboot2.7+dubbo:3.1.6
双协议注册：dubbo和rest协议
注册中心nacos：服务端版本NACOS2.0.4,客户端版本2.2.0
容器：k8s
优雅上下线问题：
下线问题：k8s上扩缩容pod时，提供者无法优雅停机，pod强制停机。(已配置dubbo.shutdownHook.listenIgnore=true和dubbo.service.shutdown.wait=30000)；同时出现ErrCode:-401, ErrMsg:Client not connected, current status:SHUTDOWN；消费者出现500错误。
上线问题：postMan通过http方式调用rest协议接口时，项目启动过程中o.apache.catalina.core.StandardService : Starting service [Tomcat]，项目还未Started Application，这时就有请求进来，造成404错误；k8s已设置就绪检查，健康检查接口通过rest协议接口实现（成功时http状态码200）；

404问题 你是不是应该通过springboot的health之类的判断， 而不是rest协议的。优雅停机，有没有试过qos方式

`Client not connected, current status:SHUTDOWN` 这个不应该影响客户端的行为。3.1 上可能 Nacos 关闭的时序有问题，可能会有一些报错，但是这个不会影响 Nacos 上节点的摘除。
