How to control log file with daily rolling and max file size by log4j?

Question

I would like to create log file that can be rolled at the beginning of the next day or if it\'s reached to specified file size and log file must be contained inside date folder.

Answer 1

From the RollingFileAppender documentation

To be of any use, a RollingFileAppender instance must have both a RollingPolicy and a TriggeringPolicy set up.... TimeBasedRollingPolicy acts both as a RollingPolicy and a TriggeringPolicy.

Hence, your SizeBasedTriggeringPolicy gets ignored since TimeBasedRollingPolicy is configured above. The only way to accommodate your requirement will be a custom classes implementation.

Also, If size of a log file really matters, you may consider using automatic gzip compression to eliminate SizeBasedTriggeringPolicy and only have your logs roll every day.
