log4j 配置 实例

可以用两个jar包中的方法。

####log4j.rootLogger是这这个工程的log输出都由下面这句话管理，实际开发的时候有许多无用的系统的log要输出占用了很的篇幅在控制台或输出的文件中，为了解决这一点。我们可以这样设置把根设置的级别高点。如：warn 这样在控制台就看不到那么多没有用的log了。但是代码中的自己写的log也被屏蔽了。所以就要再写一段children-bugger控制，用下面的代码实现。

log4j.logger.com = debug,A5
log4j.additivity.com = true
log4j.appender.A5 = org.apache.log4j.RollingFileAppender
log4j.appender.A5.File = ${catalina.home}/logs/OperateLog.log
log4j.appender.A5.MaxFileSize = 1000KB
log4j.appender.A5.MaxBackupIndex = 3
log4j.appender.A5.layout = org.apache.log4j.PatternLayout
log4j.appender.A5.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} %p: %m%n

 

log4j.logger.com = debug,A5这句代码是指向你要输出log的目录文件夹，一般为工程名文件夹。也可以定位到子目录如：log4j.logger.com.prodoc.struts.action。。。。如果还想不要子log出现在控制台，那么可以这样设置：

log4j.additivity.com = false     把它设置为FALSE就不在控制台（一般log4j.rootLogger设置为控制台，这个看你的设置而定）显示了；TRUE则显示。
