However there are situations when the same exception happens repeatedly reaching the maximum size very

问题 Hy, I have read that commons-logging and slf4j are "interfaces or specifications" for logging and you have to plugin an implementation. But I have read that you can use log4j for example with commons-logging and with slf4j too, so: log4j "implements" the specifications of commons-logging and slf4j at the same time? I dont understand it Thanks 回答1: SLF4j is a logging facade and can be introduced into both Log4j and commons-logging projects. So you use SLF4j classes to perform the logging it

The console Appender seems to work, but the error Appender continues to create a new file every time I start my program even if I am not logging any errors. I have tried setting Threshold to ERROR in the error Appender, but the file is still created every
