I might not be able to unify this pr, because we would prefer the user to actively choose which configurations need to be enabled to refresh, which might incur additional and pointless overhead if you follow the master configuration

在使用的过程中，发现大多数参数（如serverAddr）都是一样的，这样可以更加简洁。如果需要不同的参数可以明确配置。

Yes, but that's just the meta configuration data for nacos, the configuration information for the configuration file, or the user declaration

For example, it is not recommended to actively inherit the Settings of the master configuration if the configuration turns on auto refresh
