關于Log4j比較全面的配置
LOG4J的配置之簡單使它遍及于越來越多的應用中了：Log4J配置文件實現了輸出到控制臺、文件、回滾文件、發送日志郵件、輸出到數據庫日志表、自定義標簽等全套功能。擇其一二使用就夠用了，
 
log4j.rootLogger=DEBUG,CONSOLE,A1,im log4j.addivity.org.apache=true

# 應用于控制臺
 
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.Threshold=DEBUG log4j.appender.CONSOLE.Target=System.out log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=[framework] %d - %c -%-4r [%t] %-5p %c %x - %m%n #log4j.appender.CONSOLE.layout.ConversionPattern=[start]%d{DATE}[DATE]%n%p[PRIORITY]%n%x[NDC]%n%t[THREAD] n%c[CATEGORY]%n%m[MESSAGE]%n%n
 
#應用于文件
