Log4j，不同的appender，同一个包和一个单独的类，写入不同的文件？

Question

I normally associate a package to an appender. But in this one case, this class is writing a lot of logs I want to filter out to a different appender. But the class is in the same package as my other classes.

I am trying to do this:

log4j.logger.com.app=DEBUG,MainAppender
log4j.logger.com.app.webservice.Web=DEBUG,WSAppender

I want the WSAppender to write to one file but I DON'T want the same logs from the MainAppender. Right now, the logs from WSAppender also appear in MainAppender.

Answer 1

You need to set additivity=false on the child logger.

See example here .

log4j.additivity.com.app.webservice.Web = false
