Log4j2 separate log files by module name

Question

I want to write log files based on module name. for ex. one log file for user management module and one for products module etc.

My project package structure looks like below;

com.mycompany.service.user com.mycompany.service.product com.mycompany.controller.user com.mycompany.controller.product ...

I want to write log messages from com.mycompany.*.user (com.mycompany.service.user and com.mycompany.controller.user) to com.mycompany.user.log file, and com.mycompany.*.product to com.mycompany.user.log file.

I know I can create loggers like bellow

<logger name="com.mycompany.service.user" level="INFO"> <AppenderRef ref="AppenderUsers" /> </logger> <logger name="com.mycompany.controller.user" level="INFO"> <AppenderRef ref="AppenderUsers" /> </logger> ...

But this way I have to add so many loggers. Cant I use wildcard * or ** or regex to logger name somethihng like this?

<logger name="com.mycompany.*.user" level="INFO"> <AppenderRef ref="AppenderUsers" /> </logger>

Or is there any way to do this?

Finally I have solved this by writing a Custom Filter Plugin. I have used same approach used in Regex filter. But Regex filter, match given regex with Message content. But I have written a filter to match regex with class name.

I have describe this in my blog post. http://rohithag.blogspot.com/

Your blogpost is helpful, but did you ever submit a feature request to log4j2?
