Question

我的目标是每天生成日志文件，但MaxFileSize=100KB

所以我使用DailyRollingFileAppender，因为我使用的是log4j 2.2版本

日期工作正常，当我使用MaxFileSize时，它没有工作，并且没有基于filesize创建新文件仍然可以使用日期。

问题：MaxFileSize无法使用DatePattern for DailyRollingfileAppender

这是log4j.properties文件代码：

log4j.rootLogger=DEBUG, stdout, file

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

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.file.layout=org.apache.log4j.PatternLayout  
log4j.appender.file.layout.ConversionPattern=%d [%t] %-5p (%F:%L) - %m%n
log4j.appender.file.File=${catalina.home}/logs/abc
log4j.appender.file.MaxFileSize=80KB
log4j.appender.file.MaxBackupIndex=2
log4j.appender.file.DatePattern='-'yyyy-MM-dd'.log'

有些东西需要在日期模式中更改，但还不知道

Answer 1

尝试以下配置，根据时间和大小旋转文件 -

status = warn
name= properties_configuration

property.basePath = ${catalina.home}/logs/

appender.console.type = Console
appender.console.name = consoleLogger
appender.console.target = SYSTEM_OUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %level %c{1}:%L - %msg%n
appender.rolling.type = RollingFile
appender.rolling.name = fileLogger
appender.rolling.fileName=${basePath}/abc.log
appender.rolling.filePattern=${basePath}abc_%d{yyyyMMdd}-%i.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %level (%F:%L) - %msg%n
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 100 KB

# write your package name as the value of this key
logger.example.name = log4j2.example
logger.example.level = info
logger.example.additivity = false
logger.example.appenderRef.rolling.ref = fileLogger
logger.example.appenderRef.console.ref = consoleLogger

rootLogger.level = error
rootLogger.additivity = false
rootLogger.appenderRef.rolling.ref = fileLogger
rootLogger.appenderRef.console.ref = consoleLogger

这是基于xml的配置，它工作正常，但确切的属性或基本配置不起作用。文件未创建且没有控制台输出

使用DailyRollingFileAppender的Log4j MaxFileSize
