log4j:WARN org.apache.log4j.DailyRollingFileAppender中没有这样的属性[maxFileSize]

Question

一切都很好.但显示此错误.

我的log4j.properties文件如:

# 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

提前致谢.告诉我该怎么做.我只想在每日滚动日志文件.

Answer 1

DailyRollingFileAppender不支持MaxFileSize RollingFileAppender.

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,则应删除该MaxFileSize属性.
