Log4J通用配置|注意問題 筆記

 #這裏定義能顯示到的最低級別,若定義到INFO級別,則看不到DEBUG級別的信息了~!
log4j.rootLogger=INFO,allLog

# DAO層 log記錄到dao.log 控制檯 和 總日誌文件
log4j.logger.DAO=INFO,dao,Console,allLog   
    
# 業務層 log記錄到service.log   控制檯 和 總日誌文件
log4j.logger.SERVICE=INFO,service,Console,allLog

# 測試 及 日常日誌打印  log記錄到 common.log   控制檯 和 總日誌文件
log4j.logger.COMMON=INFO,common,Console,allLog

Log4J配置後， log4j:ERROR setFile(null,true) call failed. 報錯：java.io.FileNotFoundException: \log\mytest2.log (系統找不到指定的路徑。) 收藏 
是log4j.properties與tomcat的log4j重名的原因 

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

因爲在tomcat啓動是默認去找log4j.properties,但此時Listener還沒有起來,tomcat就要往\WEB-INF\logs\log4j.log 寫日誌就找不到了 
相關spring log4j的資料
