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

修饰符和类型	方法	说明
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.
default void	DynamicConfiguration.addListener(String key, ConfigurationListener listener)	DynamicConfiguration.addListener(String, String, ConfigurationListener)
void	TreePathDynamicConfiguration.addListener(String key, String group, ConfigurationListener listener)
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.
default void	DynamicConfiguration.removeListener(String key, ConfigurationListener listener)	DynamicConfiguration.removeListener(String, String, ConfigurationListener)
void	TreePathDynamicConfiguration.removeListener(String key, String group, ConfigurationListener listener)

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

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

修饰符和类型	方法	说明
void	NopDynamicConfiguration.addListener(String key, String group, ConfigurationListener listener)	已过时。
void	NopDynamicConfiguration.removeListener(String key, String group, ConfigurationListener listener)	已过时。
