log4j:WARN无法识别的元素rollingPolicy [英] log4j:WARN Unrecognized element rollingPolicy

问题描述

我的应用程序启动时，我在日志中有此警告

I had this warning in log when my application was starting

log4j:WARN Unrecognized element rollingPolicy

试图向Google寻求答案，但是添加apache-log4j-extras-1.1.jar并没有帮助我.

tried to Google for answers, but adding apache-log4j-extras-1.1.jar didn't helped me.

我正在将slf4j-log4j12 1.7.2与log4j 1.2.17一起使用.

推荐答案

我使用的是DailyRollingFileAppender，而不是rollingPolicy.

Instead of rollingPolicy I used DailyRollingFileAppender and no extras jar is needed.

<appender name="rollingLog" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="${catalina.home}/logs/rolling.log" />
    <param name="append" value="true" />
    <layout class="org.apache.log4j.PatternLayout"> 
        <param name="ConversionPattern" value="%d{ISO8601} %-5p [%t] [%c] %m%n"/> 
    </layout> 
</appender>
