org.apache.dubbo.common.config.configcenter中ConfigurationListener的使用

参数类型为ConfigurationListener的org.apache.dubbo.common.config.configcenter中的方法

限定符和类型	方法和说明
default void	DynamicConfiguration.addListener(String key, ConfigurationListener listener) DynamicConfiguration.addListener(String, String, ConfigurationListener)
void	AbstractDynamicConfiguration.addListener(String key, String group, ConfigurationListener listener)
void	DynamicConfiguration.addListener(String key, String group, ConfigurationListener listener) Register a configuration listener for a specified key The listener only works for service governance purpose, so the target group would always be the value user specifies at startup or 'dubbo' by default.
void	TreePathDynamicConfiguration.addListener(String key, String group, ConfigurationListener listener)
default void	DynamicConfiguration.removeListener(String key, ConfigurationListener listener) DynamicConfiguration.removeListener(String, String, ConfigurationListener)
void	AbstractDynamicConfiguration.removeListener(String key, String group, ConfigurationListener listener)
void	DynamicConfiguration.removeListener(String key, String group, ConfigurationListener listener) Stops one listener from listening to value changes in the specified key.
void	TreePathDynamicConfiguration.removeListener(String key, String group, ConfigurationListener listener)
