log4J: 使用TimeBasedRollingPolicy的收盘后翻转动作失败[英] log4J: Failure in post-close rollover action using TimeBasedRollingPolicy

问题描述

I have setup TimeBasedRollingPolicy to rollout the file every minute (for test purpose) and the problem I am facing is a warning and no zip or gz file is being created. Warning is:

log4j:WARN Failure in post-close rollover action

I attached the source to figure-out the problem but have no success yet. Am I missing any configuration in my log4j.xml?

<appender name="errorAppender" class="org.apache.log4j.rolling.RollingFileAppender">
        <param name="File" value="C:/error.log"/>
        <param name="Append" value="true"/>
        <param name="BufferedIO" value="true"/>
        <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
            <param name="FileNamePattern" value="C:/error.%d{ddMMMyyyy HH:mm:ss}.log.gz" />
        <param name="ActiveFileName" value="C:/error.log"/>
    </rollingPolicy>

        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d [%t] %-5p %C (line:%L) - %m%n"/>
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMax" value="error"/>
            <param name="LevelMin" value="error"/>
            <param name="AcceptOnMatch" value="true"/>
        </filter>
    </appender>

I am using log4j-1.2.17 and apache-log4j-extras-1.1. Has anybody seen this problem or have any clue about it?

Problem with "log4j:WARN Failure in post-close rollover action" message is that in windows-based systems you can not create a file name with the ":" char, so the FileNamePattern specified should not contain any one of these: \, /, :, *, ?, ", <, >, |

Here it is a log4j.xml for my application that works fine using a rolling file appender. For testing purposes I made the rolling to create a new file every second:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
  <appender name="consola" class="org.apache.log4j.ConsoleAppender"> 
    <param name="target" value="System.out"/> 
    <layout class="org.apache.log4j.PatternLayout"> 
      <param name="conversionPattern" value="[%d{yyyyMMdd HH:mm:ss:mm,SSS}]%-5p [%t] [%c{1}-%M:%L] - %m%n"/>
    </layout> 
  </appender> 

  <appender name="desarr" class="org.apache.log4j.rolling.RollingFileAppender">
    <param name="Append" value="false"/>
    <rollingPolicy name="desarr" class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
        <param name="fileNamePattern" value="C:/workspace/Probador/log/backups/importacion222.log_%d{mmss_mm}"/>
        <param name="activeFileName" value="C:/workspace/Probador/log/importacion222.log"/>
    </rollingPolicy> 
   <layout class="org.apache.log4j.PatternLayout"> 
        <param name="conversionPattern" value="[%d{yyyyMMdd HH:mm:ss:mm,SSS}]%-5p [%t] [%c{1}-%M] - %m%n"/>
   </layout> 
  </appender> 

  <root> 
    <priority value ="debug" /> 
    <appender-ref ref="consola" /> 
    <appender-ref ref="desarr"/>
  </root>

</log4j:configuration>

Special attention to:

<param name="fileNamePattern" value="C:/workspace/Probador/log/backups/importacion222.log_%d{mmss_mm}"/>

Try this before attempting to zip the file.

I hit the same issue in log4j with WARN message - "log4j:WARN Failure in post-close rollover action" and the log file was not rolling over. It was root caused to insufficient permission issue on the directory into which log file was getting written. In this case, Java's File.renameTo() method was failing silently (just returns a boolean false). Took lot of time to figure out the issue :(

I have also observed this problem using log4j-1.2.16 and apache-log4j-extras-1.1. The exact same message.

I have tried various tweaks to no avail. The only time when rollingPolicy->FileNamePattern seems to be observed is when it is used without the appender->File parameter and rollingPolicy->ActiveFileName parameter. But even still I have not seen it rollover successfully nor gz or zip previous files.

I also get the same messages:

log4j: setFile called: somepath/somefile.log, true
log4j: setFile ended
log4j:WARN Failure in post-close rollover action

Very frustrating.
