[GitHub] [dubbo] haoxz11 opened a new issue, #10934: Dubbo3下扫描接口注册服务（zookeeper注册中）时告警问题
haoxz11 opened a new issue, #10934:
URL: https://github.com/apache/dubbo/issues/10934
<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy -->
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 3.1.2
* Operating System version: mac m1
* Java version: 17
### Steps to reproduce this issue
Dubbo3下扫描接口注册服务时，由于会扫描（providers,configurators,routers）三个节点的服务，通常providers排在最后，这个时候
这段代码下会由于前面已经有缓存，会导致告警出现：
2022-11-14 10:26:51.161 WARN [main] org.apache.dubbo.registry.integration.RegistryDirectory:? - XXXX received empty address list with no EMPTY protocol set, trigger empty protection., dubbo version: 3.1.2, current host: 172.16.11.12, error code: 1-4. This may be caused by configuration , go to https://dubbo.apache.org/faq/1/4 to find instructions.
建议
将判断条件拆分这样就可以避免告警，不然当该服务有大量的消费者服务时，有非常多的告警出现；

不一样的，localCached只有在invokerUrls有值得时候才会赋值，而之前是为空也会赋值

应为providers,configurators,routers，三个节点，正常情况下只会有一个有值，前面的条件判断，而就算invokerUrls为空也会对localCached赋值，现在只要调整一下条件，只有invokerUrls有值才会赋值，这样启动就不会触发告警；
