log4j 按照日期和输出类型分割日志文件

1、按照大小分割

#定义LOG输出级别
log4j.rootLogger=DEBUG,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/gi.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

2、按照日期 和类型分割

log4j.rootLogger=info,stdout,info,error
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
log4j.logger.info=info
log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
log4j.appender.info.layout=org.apache.log4j.PatternLayout
log4j.appender.info.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
log4j.appender.info.Threshold= INFO
log4j.appender.info.append=true
log4j.appender.info.File=logs/log_info_
log4j.appender.info.DatePattern=yyyy-MM-dd'.log'
#log4j.logger.debug=debug
#log4j.appender.debug=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.debug.layout=org.apache.log4j.PatternLayout
#log4j.appender.debug.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
#log4j.appender.debug.datePattern='.'yyyy-MM-dd
#log4j.appender.debug.Threshold = DEBUG
#log4j.appender.debug.append=true
#log4j.appender.debug.File=logs/debug.log

log4j.logger.error=error
log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.layout=org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
log4j.appender.error.Threshold = ERROR
log4j.appender.error.append=true
log4j.appender.error.File=logs/log_error_
log4j.appender.error.DatePattern=yyyy-MM-dd'.log'
log4j.appender.file.layout=org.apache.log4j.PatternLayout
