问题描述

一切正常.但是显示此错误.

Everything works just as fine. But showing this error.

我的log4j.properties文件如:

My log4j.properties file like :

# Root logger option
log4j.rootLogger=DEBUG, stdout, file

# Redirect log messages to console
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=%d{yyyy-MM-dd HH:mm:ss} %-5p    %c{1}:%L - %m%n

# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.file.File=D:\\log4j-application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
 log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

先谢谢了.告诉我怎么做.我只想每天滚动的日志文件.

Thanks in advance. Just tell me how to do it. I just want log file on daily rolling .

推荐答案

DailyRollingFileAppender不支持MaxFileSize，RollingFileAppender则支持.

DailyRollingFileAppender doesn't support MaxFileSize, RollingFileAppender does.

DailyRollingFileAppender用于根据日志条目的日期和时间滚动文件，因此，如果要使用它，则应删除MaxFileSize属性.

DailyRollingFileAppender is for rolling files based on the date and time of the log entry, so if you want to use it you should remove the MaxFileSize property.
