问题描述

我正在使用log4j1.2.17和apache-extras-log4j--1.2.17.Jar登录.

我的目的是根据size滚动和存档文件.BELOW是log4j.xml

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

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <appender name="R" class="org.apache.log4j.rolling.RollingFileAppender">
    <param name="File" value="logger.log"/> 
    <param name="append" value="true"/>
    <param name="encoding" value="UTF-8"/>      
    <rollingPolicy class="org.apache.log4j.rolling.FixedWindowRollingPolicy">
        <param name="FileNamePattern" value="logger.log%i.gz" />            
    </rollingPolicy>
    <triggeringPolicy class="org.apache.log4j.rolling.SizeBasedTriggeringPolicy">
        <param name="MaxFileSize" value="${LOG_FILESIZE_LIMIT}"/>
    </triggeringPolicy>
    <layout class="org.apache.log4j.TTCCLayout">
      <param name="ContextPrinting" value="true"/>
      <param name="ThreadPrinting" value="true"/>
      <param name="DateFormat" value="MM/dd/yyyy HH:mm:ss"/>
    </layout>
   </appender>

  <root>
    <priority value ="DEBUG"/>
    <appender-ref ref="R"/>

  </root>

</log4j:configuration>

$ {log_filesize_limit}是100MB.

，但它没有将maxfilesize设置为100MB并提供以下消息.

log4j:警告未能将属性[maxfilesize]设置为" 100MB"

将默认的maxfilesize(即10MB)归档，然后将其归档到10MB.

谢谢 anjali

检查classPath上是否没有其他版本的log4j，我遇到了一个问题，在另一个第三方的罐子集也有较旧的log4j版本 - 将其删除解决了问题.

I am using log4j1.2.17 and apache-extras-log4j--1.2.17.jar for logging.

My purpose is to roll and archive the file based on size.Below is the log4j.xml

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

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <appender name="R" class="org.apache.log4j.rolling.RollingFileAppender">
    <param name="File" value="logger.log"/> 
    <param name="append" value="true"/>
    <param name="encoding" value="UTF-8"/>      
    <rollingPolicy class="org.apache.log4j.rolling.FixedWindowRollingPolicy">
        <param name="FileNamePattern" value="logger.log%i.gz" />            
    </rollingPolicy>
    <triggeringPolicy class="org.apache.log4j.rolling.SizeBasedTriggeringPolicy">
        <param name="MaxFileSize" value="${LOG_FILESIZE_LIMIT}"/>
    </triggeringPolicy>
    <layout class="org.apache.log4j.TTCCLayout">
      <param name="ContextPrinting" value="true"/>
      <param name="ThreadPrinting" value="true"/>
      <param name="DateFormat" value="MM/dd/yyyy HH:mm:ss"/>
    </layout>
   </appender>

  <root>
    <priority value ="DEBUG"/>
    <appender-ref ref="R"/>

  </root>

</log4j:configuration>

${LOG_FILESIZE_LIMIT} is 100MB.

But its not setting the MaxFileSize to 100MB and gives below message.

log4j:WARN Failed to set property [maxFileSize] to value "100MB"

Its taking default maxfilesize which is 10MB and archiving the file once it reaches to 10MB.

Thanks, Anjali

Check that there are no other versions of log4j on the classpath, I had this problem before where another third party set of jars also had an older version of log4j - removing it fixed the problem.
