JAVA log4j日志文件使用

2017-05-06 02:40

//1.导入jar包,log4j-1.2.17.jar
//2.src下创建log4j.properties文件
//3.配置properties文件
/*
log4j.rootLogger(默认是对整个工程生效)=DEBUG,stdout(控制台),a, b, …
日志级别(ALL<DEBUG<INFO<WARN<ERROR<FATAL<OFF)
log4j.logger.com.hutu=info, stdout,表示该日志只对package com.hutu生效

log4j.appender.a=org.apache.log4j.日志输出到哪儿
ConsoleAppender(控制台)
FileAppender(文件)
DailyRollingFileAppender(每天产生一个日志文件)
RollingFileAppender(文件大小到达指定尺寸时产生一个新的文件)
WriteAppender(将日志信息以流格式发送到任意指定的地方)
JDBCAppender(将日志信息保存到数据库中)
log4j.appender.a.File=文件目录及文件路径${user.home}/logs/...
log4j.appender.a.MaxFileSize=最大文件大小100m
log4j.appender.a.MaxBackupIndex=备份文件个数10
log4j.appender.ServerDailyRollingFile.DatePattern='.'yyyy-MM-dd 日志后缀格式
log4j.appender.a.layout=org.apache.log4j.日志布局格式
HTMLLayout(以HTML表格形式布局)
SimpleLayout(包含日志信息的级别和信息字符串)
TTCCLayout(包含日志产生的时间,执行绪,类别等信息)
PatternLayout(可以灵活的指定布局格式,常用)
log4j.appender.a.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p [%c] %m%n日志输出格式
log4j.appender.ServerDailyRollingFile.Append=true
