反映配置文件更改的Log4j？

Question

If I make a change to a Log4j configuration file, do I have to restart my application for the changes to take affect, or does Log4j notice the changes and reconfigure itself?

Does it do this under some circumstances and not others?

Answer 1

DOMConfigurator.configureAndWatch(log4jConfigurationFilePath, delayInmilisecond)

如果您喜欢xml。，则可以使用上述方法反映log4j配置文件中的更改。如果您喜欢属性文件，则可以使用PropertConfigurator.configureAndWatch方法。
