好用的log4j.properties配置文件（按照级别打印日志，每天生成不同类型的日志，可以打印sql日志）

日志按照级别分类

log4j.rootLogger = INFO,stdout,D,E,I
#ShuChuDaoDaYingTai
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
log4j.appender.stdout.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %l -%m%n
#log4j.appender.stdout.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %p %c -%m%n
#DEBUG
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File =${env.log4j.logfile}/webDebug.log
log4j.appender.D.File.DatePattern='.'yyyy-MM-dd
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
#log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss.SSS} [ %t:%r ] - [ %p ] %m%n
log4j.appender.D.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %l -%m%n
#ERROR
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =${env.log4j.logfile}/webError.log
log4j.appender.E.File.DatePattern='.'yyyy-MM-dd
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %l -%m%n
#log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss.SSS} [ %t:%r ] - [ %p ] %m%n
#INFO
log4j.appender.I = org.apache.log4j.DailyRollingFileAppender
log4j.appender.I.File =${env.log4j.logfile}/webInfo.log
log4j.appender.I.File.DatePattern='.'yyyy-MM-dd
log4j.appender.I.Append = true
log4j.appender.I.Threshold = INFO
log4j.appender.I.layout = org.apache.log4j.PatternLayout
log4j.appender.I.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss.SSS} %l %m%n

　还可以在下面加入打印运行sql的日志

log4j.rootLogger=DEBUG,Console
  
#Console  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
