### 设置###
log4j.rootLogger = debug,stdout,D,E
### 输出信息到控制抬 ###
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 = [%p] %d{yyyy-MM-dd HH:mm:ss} %m%n
### 输出DEBUG 级别以上的日志到=log.log ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = C://Data/log.log
log4j.appender.D.Append = true

### 输出ERROR 级别以上的日志到=error.log ###
