zhangyz-hd opened a new issue #8370: URL: https://github.com/apache/dubbo/issues/8370
- [x] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. - [x] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.0.2-SNAPSHOT * Operating System version: ANY * Java version: 8 ### Steps to reproduce this issue 服务提供者端，传统服务发现模式，配置中心使用zookeeper或者apollo，注册2个服务 ``` <dubbo:registry address="zookeeper://127.0.0.1:2181"/> <dubbo:config-center address="zookeeper://127.0.0.1:2182"/> ``` 消费者启动后，会在配置中心监节点级别的动态配置和服务级别的动态配置，以zookeeper为例，会监听： 1. 节点级，path=/dubbo/config/dubbo/demo-provider.configurators 2. 服务级，path1=/dubbo/config/dubbo/org.apache.dubbo.demo.DemoService:1.2.3:G1.configurators 3. 服务级，path1=/dubbo/config/dubbo/org.apache.dubbo.demo.GreetingService:4.5.6:G2.configurators #### 场景1，节点级配置 向`/dubbo/config/dubbo/demo-provider.configurators`写入DemoService的动态配置 ``` configVersion: v2.7 scope: service key: G1/org.apache.dubbo.demo.DemoService:1.2.3 configs: - addresses: ['0.0.0.0:20880'] side: provider parameters: weight: 222 ``` 根据提供者reExport日志，发现DemoService和GreetingService都按weight=222进行了重注册。 #### 场景2，服务级配置 向`/dubbo/config/dubbo/org.apache.dubbo.demo.DemoService:1.2.3:G1.configurators`写入DemoService的动态配置 ``` configVersion: v2.7 scope: service key: AAAAA <--瞎写就行 configs: - addresses: ['0.0.0.0:20880'] side: provider parameters: weight: 333 ``` 根据提供者reExport日志，发现DemoService按weight=333进行了重注册。 #### 总结 1. 可以发现yaml中的key没有实际存在的意义，因为key中的服务信息，在DynamicConfiguration实现，以及ConfigChangeListener中都有，在AbstractConfiguratorListener#genConfiguratorsFromRawRule传入即可。此处key属性可取消。 2. 作为scope: service的配置，写入节点级配置路径也能生效，此处最好能控制监听逻辑。节点级只响应scope:application的yaml，服务级只响应scope:service的yaml，或者也可取消scope属性。 -- This is an automated message from the Apache Git Service.
