What is the difference between log4j RollingFileAppender vs DailyRollingFileAppender? and why would I use one verses the other?

回答1:

Reading http://www.mail-archive.com/log4j-user@logging.apache.org/msg08183.html

• DailyRollingFileAppender - Rotates based on dateFormat
• RollingFileAppender - Rotates based on a maximum file size.

回答2:

On DailyRollingFileAppender the file is rolled over at a user chosen frequency, but on RollingFileAppender the file is rolled when the file reaches certain size.
