Log Level per appender for a single Logger

Is it possible to configure different log levels for a single Logger based on the appender?

I realize this is simi开发者_如何学Clar to this question, and this is as far as I had already got myself, but the problem with this is that the threshold applies to all loggers that log to that appender, whereas I only want the threshold to apply to a single logger.

i.e. So far I have something like this:

log4j.rootLogger=WARN, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold=WARN
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout

log4j.logger.mylogger=DEBUG,logfile
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.DatePattern=${roll.pattern.daily}
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d{${datestamp}} [%t] %-5p %C{2} - %m%n
log4j.appender.logfile.File=mylogfile.log

I want mylogger DEBUG messages to be send to the logfile appender, but I also want mylogger INFO messages to be sent to the stdout appender (but for all other loggers only WARN ings). Using the Threshold to limit stdout to WARN restricts the output of mylogger.

Aha, I fixed it by changing

log4j.appender.stdout.Threshold=WARN

to

log4j.appender.stdout.Threshold=INFO

Should have been more careful first time round.
