### 设置级别和目的地(这里多个目的地) ###
log4j.rootLogger = DEBUG,CONSOLE,zhangsanLog
### 这里的me是包，也就是在这个包记录日志时，是只记录debug及以上级别的日志
log4j.logger.me=DEBUG
### 输出到控制台 ###
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{ABSOLUTE} %5p %c{1}:%L - %m%n

### 输出到日志文件 ###
log4j.appender.zhangsanLog = org.apache.log4j.DailyRollingFileAppender
log4j.appender.zhangsanLog.File =G\:\\untitled\\debug.log
#log4j.appender.zhangsanLog.File =/var/alldata/zhenduan/debug.log
log4j.appender.zhangsanLog.Append = true
## 只输出DEBUG级别以上的日志
log4j.appender.zhangsanLog.Threshold = DEBUG
