关于日志的等级 的配置

#这里定义能显示到的最低级别,若定义到INFO级别,则看不到DEBUG级别的信息了~!

log4j.rootLogger=INFO,allLog

#DAO层log记录到dao.log控制台和总日志文件

log4j.logger.DAO=INFO,dao,Console,allLog

#业务层log记录到service.log控制台和总日志文件

log4j.logger.SERVICE=INFO,service,Console,allLog

#测试及日常日志打印log记录到common.log控制台和总日志文件

log4j.logger.COMMON=INFO,common,Console,allLog

log4j.appender.Console=org.apache.log4j.ConsoleAppender

log4j.appender.Console.layout=org.apache.log4j.PatternLayout

log4j.appender.Console.layout.ConversionPattern=%d%p-%C{1}.%M(%L)-%m%n

log4j.appender.service.layout=org.apache.log4j.PatternLayout

Log4J配置后，log4j:ERRORsetFile(null,true)callfailed.报错：java.io.FileNotFoundException:\log\mytest2.log(系统找不到指定的路径。)收藏

是log4j.properties与tomcat的log4j重名的原因

你把/WEB-INF/classes/log4j.properties的log4j配置文件改个名字就OK了！(如:log.properties)

因为在tomcat启动是默认去找log4j.properties,但此时Listener还没有起来,tomcat就要往\WEB-INF\logs\log4j.log写日志就找不到了
