how to define my own log file name

[kingwell]

Hi all,
I want to define the log file name pattern like yyyymmdd-mylog.log, how to
do so using log4j?
As the DailyRollingFileAppender is just append the yyymmdd pattern to the
end of the file name, something like mylog.log.yyyymmdd. Do I need to write
my own appender class, or can anyone provide some helpful util class?

 

Thanks for help!
