Configure log4j log file name if it is rolling?

问题

log4j.properties:

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=PATH_TO_LOGS/logs/rolling.log
log4j.appender.file.DatePattern='.'yyyy-MM-dd-HH-mm
log4j.appender.file.threshold=debug
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%-5p] %d %c - %m%n
log4j.rootLogger=debug,file

My log file is rolling every minute. But my problem is I want the rolled log file name to be: rolling.2016-03-17-11-11.log

instead of

rolling.log.2016-03-17-11-11

Instead of:

log4j.appender.file.File=PATH_TO_LOGS/logs/rolling.log
log4j.appender.file.DatePattern='.'yyyy-MM-dd-HH-mm

Changed to:

log4j.appender.file.File=PATH_TO_LOGS/logs/rolling
log4j.appender.file.DatePattern='.'yyyy-MM-dd-HH-mm'.log'
