log4j:WARN org.apache.log4j.RollingFileAppender 中没有这样的属性 [rollingPolicy]

Question

我正在使用 log4j-1.2.16.jar 和 apache-log4j-extras-1.2.17.jar。

我想启用文件名后附加日期的滚动文件。但是显示此错误并且文件未按预期旋转。

我的 log4j.properties 文件如下所示。

zookeeper.root.logger=DEBUG, ROLLINGFILE
zookeeper.console.threshold=DEBUG
zookeeper.log.dir=/path/to/logs
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=DEBUG
zookeeper.tracelog.dir=.
zookeeper.tracelog.file=zookeeper_trace.log
log4j.appender.ROLLINGFILE=org.apache.log4j.RollingFileAppender
log4j.appender.ROLLINGFILE.Threshold=${zookeeper.log.threshold}
log4j.appender.ROLLINGFILE.File=${zookeeper.log.dir}/${zookeeper.log.file}
log4j.appender.ROLLINGFILE.rollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.ROLLINGFILE.rollingPolicy.fileNamePattern=${zookeeper.log.dir}/app%d{yyyy-MM-dd}.log
log4j.appender.ROLLINGFILE.MaxFileSize=20KB
log4j.appender.ROLLINGFILE.MaxBackupIndex=100000
log4j.appender.ROLLINGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.ROLLINGFILE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L] - %m%n

Answer 1

设法修复它。问题出在 org.apache.log4j.RollingFileAppender。一旦我将其更改为org.apache.log4j.rolling.RollingFileAppender

，它就起作用了

zookeeper.root.logger=DEBUG, ROLLINGFILE
zookeeper.console.threshold=DEBUG
zookeeper.log.dir=/path/to/logs
zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=DEBUG
zookeeper.tracelog.dir=.
zookeeper.tracelog.file=zookeeper_trace.log
log4j.appender.ROLLINGFILE=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.ROLLINGFILE.Threshold=${zookeeper.log.threshold}
log4j.appender.ROLLINGFILE.File=${zookeeper.log.dir}/${zookeeper.log.file}
log4j.appender.ROLLINGFILE.rollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.ROLLINGFILE.rollingPolicy.fileNamePattern=${zookeeper.log.dir}/app%d{yyyy-MM-dd}.log
log4j.appender.ROLLINGFILE.MaxFileSize=20KB
log4j.appender.ROLLINGFILE.MaxBackupIndex=100000
log4j.appender.ROLLINGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.ROLLINGFILE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L] - %m%n

Answer 2

查看 org.apache.log4j.rolling.RollingFileAppender 的代码，它来自一个单独的 apache-log4j-extras 包，这个解决方案是行不通的。虽然 class 有 rollingPolicy & rollingPolicy.fileNamePattern 字段，但它没有 maxFileSize & maxBackupIndex 字段。您检查错误日志了吗？

相反org.apache.log4j.RollingFileAppenderclass。它有 MaxFileSize & maxBackupIndex 字段但没有 rollingPolicy & rollingPolicy.fileNamePattern 个字段。它只是没有两种口味。
