Question

我从旧的（和不安全的）DailyRollingFileAppender切换到新的RollingFileAppender。所以现在我想测试我的配置但是我似乎无法触发翻转机制。 log4j检查哪一次决定翻转日志？我试着将系统时间设置回/将来，更改日志中的时间，更改文件时间......没有运气！或者我的配置错了？

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

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

     <appender name="fileAppender" class="org.apache.log4j.rolling.RollingFileAppender">
        <param name="file" value="some.log" />
        <param name="append" value="true" />
        <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
            <param name="FileNamePattern" value="%d.log" />
        </rollingPolicy>
        <layout class="org.apache.log4j.EnhancedPatternLayout">
            <param name="ConversionPattern" value="[%d{dd.MM.yyyy HH:mm:ss,SSS}] [%-5p] %c - %m%n" />
        </layout>
    </appender>

...<!--appreviated for clarity-->

</log4j:configuration>

    DailyRollingFileAppender - Rotates based on dateFormat
    RollingFileAppender - Rotates based on a maximum file size.
