How to use log4j to log a file whose file name is daily based?

[Hai Lin]

Hi All,
I'm using log4j to do log for the java application, and the logged file name should be automatically changed every day, for example, today's log file should be 12152004test1.log (today is Dec/15), and tomorrow's log will automatically become 12162004test1.log when I start up the application.
Could anyone tell me how to set the property about:

log4j.rootCategory=DEBUG, MYLOG
log4j.appender.MYLOG.File=C:\\tomcat\\webapps\\test\\...

Thanks a lot.

Hi Lin,

You can get different log file by adding this below line to your file

log4j.appender.MYLOG=org.apache.log4j.DailyRollingFileAppender

This will create a new text file at the end of day. then u will get a seperate file for each day.


To test this, run your java program by changing dates.

Hope this helps you.

All the Best.
