Log4j ---- 通过配置文件进行配置

log4j.properties

 

 

log4j.rootLogger = All,out1,out2,out3,out4
log4j.appender.out1 = org.apache.log4j.ConsoleAppender

log4j.appender.out2 = org.apache.log4j.FileAppender
log4j.appender.out2.File = forder/all.log

log4j.appender.out3 = org.apache.log4j.DailyRollingFileAppender
log4j.appender.out3.File = forder/day.log

log4j.appender.out4 = org.apache.log4j.RollingFileAppender
log4j.appender.out4.File = forder/max.log
log4j.appender.out4.MaxFileSize = 1kb

log4j.appender.out1.layout = org.apache.log4j.SimpleLayout
log4j.appender.out2.layout = org.apache.log4j.PatternLayout
log4j.appender.out3.layout = org.apache.log4j.PatternLayout
log4j.appender.out4.layout = org.apache.log4j.PatternLayout

log4j.appender.out2.layout.ConversionPattern = %d-[TS] %p %t %c - %m%n
log4j.appender.out3.layout.ConversionPattern = %d-[TS] %p %t %c - %m%n
log4j.appender.out4.layout.ConversionPattern = %d-[TS] %p %t %c - %m%n
