Java – log4j Logging in mehrere Dateien

Um aus einer Anwendung in mehrere Dateien zu loggen kann folgendes in die log4j.properties geschrieben werden:

 

log4j.rootLogger=debug, weblogger, dblogger

#Define which packages use which appenders
log4j.logger.com.mycorp.web=DEBUG,weblogger
log4j.logger.com.mycorp.db=INFO,dblogger

#Ensure the logs don't add to each other
log4j.additivity.com.mycorp.web=false
log4j.additivity.com.mycorp.db=false

#Define web appender
log4j.appender.weblogger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.weblogger.File=/var/log/myapp/web.log
log4j.appender.weblogger.DatePattern='.'yyyy-MM-dd
log4j.appender.weblogger.Append=true
log4j.appender.weblogger.layout=org.apache.log4j.PatternLayout
log4j.appender.weblogger.layout.ConversionPattern=%d [%t] %-5p %c{1} - %m %n

#Define db appender
log4j.appender.dblogger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.dblogger.File=/var/log/myapp/db.log
log4j.appender.dblogger.DatePattern='.'yyyy-MM-dd
log4j.appender.dblogger.Append=true
log4j.appender.dblogger.layout=org.apache.log4j.PatternLayout
log4j.appender.dblogger.layout.ConversionPattern=%d [%t] %-5p %c{1} - %m %n
