使用官方的dubbo集成CSE的demo，CSE的注册中心和配置中心替换成https的地址时，报错。日志如下： 13/12/21 18:59:22:819 CST] main INFO config.ServiceConfig: [DUBBO] No valid ip found from environment, try to find valid host from DNS., dubbo version: 2.7.8, current host: 172.16.1.252 [13/12/21 18:59:22:866 CST]...

问题现象： consumer调用provider时，一直调用到下游已下线的实例上，业务异常受损。 问题根因： servicecomb-client定时从注册中心拉取实例中出现异常时，删除缓存中该服务的相应信息，而缓存中的服务信息只有启动时初始化，所以后期都将无法刷新dubbo中的缓存信息 解决方案： 新建请求拦截Filter，在客户端调用过程中调用注册缓存监听信息，如果缓存中存在则不作更新，不存在重新从注册中心拉取，并更新服务端缓存信息
