如下所示 ：
log4j.rootlogger = info, stdout, info, debug, warn, fehler log4j.appender.stdout = org.apache.log4j.conoleAppender log4j.appender.stdout.layout = org.apache.log4j.patterlayout log4j.appender.stdout.layout.ConversionPattern = %-d {yyyy-mm-dd hh: mm: ss} [ %t: %r]-[ %p] %m %n log4j.logger log4j.appender.info.layout=org.apache.log4j.PatternLayout log4j.appender.info.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n log4j.appender.info.datepattern = '.' yyyy-mm-dd log4j.appender.logfile.maxFileSize = 5120KB log4j.appender.logfile log4j.appender.info.file =/usr/local/tomcat7/logs/info.log log4j.logger.debug = debug log4j.appender.debug = org.apache.log4j.dailyrollingFileAppender log4j.appender.debug.layout = org.apache.apache.log4j.Patter.debug.lay.layout = org.apache.apache.log4j.Patter.debug.lay.layout = org.apache.apache.log4j.Patter.Debug.lay.layout = org.apache.apache.log4j.Patter.debug.lay.layout = org.apache.apache.apache.log4j.Patter.debug.lay.layout = org.apache.apache.log4j.PaTaTenders. log4j.appender.debug.layout.ConversionPattern = %-d {yyyy-mm-dd hh: mm: ss} [ %t: %r]-[ %p] %M %n log4j.appender.debug.datepatter = '. log4j.appender.logfile.maxbackupupindex = 3 log4j.appender.debug.threshold = debug log4j.appender.debug.append = true log4j.appender.debug.file =/usr/local/tomcat7/logs/debug.log log4j.appender.warn = org.apache.log4j.dailyrollingFileAppender log4j.appender.warn.layout = org.apache.log4j.patternLayout log4j.appender.warn.layout.ConversionPattern = %t: %t: {YYYYYYYYYYY MM: MM: MM: MM. %m %n log4j.appender.warn.datepattern = '.'
