如何清除Log4j 2.3每日滚动文件附加器的日志

公西毅
2023-03-14

我目前正在使用log4j2为我的web应用程序编写日志。我已经配置了一个滚动文件追加器，可以在每晚午夜滚动。

我的log4j2.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %c{36} - %msg%n"/>
        </Console>
        <RollingFile
            name="ApplicationLog"
            fileName="${sys:catalina.base}/logs/application.log"
            filePattern="${sys:catalina.base}/logs/application %d{yyyy-MM-dd}.log">
              <PatternLayout>
                  <Pattern>%d{HH:mm:ss.SSS} [%t] %-5level %c{36} %l: %msg%n</Pattern>
              </PatternLayout>
              <Policies>
                  <TimeBasedTriggeringPolicy interval="1" modulate="true"/>
              </Policies>
              <DefaultRolloverStrategy/>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="my.package" level="info" additivity="false">
            <AppenderRef ref="ApplicationLog"/>
        </Logger>
        <Logger name="my.test.package" level="debug" additivity="false">
            <AppenderRef ref="Console"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

目前，这会写入名为application.log的日志，然后在午夜将当前的application.log文件复制到application yyy-MM-DD . log(文件名中的日期会被正确替换)，并在第二天继续在application.log中记录日志。

我希望application.log在新的一天开始之前被清除。目前，这种情况还没有发生，因此我的日志大小一直在增加。我的第1天日志包含第1天的所有日志，但我的第2天日志包含第1天和第2天的日志，依此类推。

如何重置应用程序。一旦发生翻滚，是否记录文件？根据Log4j 2.x文档，这是一个新的应用程序。应该创建日志文件，而不是继续当前文件，但这不是我正在经历的行为。

任何帮助将不胜感激。

谢谢，亚当

看起来和你面临的问题一样。

检查日志文件夹的文件夹权限，并向其授予写入权限。

chmod 666 logs

我通过调试源代码来解决这个问题，因为我的日志应该会滚动。

显然，有一个未记录的属性可以放在名为“append”的RollingFile元素中，当设置为false时，它将从一开始写入当前日志文件。不幸的是，此属性的默认值为true，这会导致追加当前日志文件，而不是重新启动。

因此，我的最后一个log4j2.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %c{36} - %msg%n"/>
        </Console>
        <RollingFile
            name="ApplicationLog"
            fileName="${sys:catalina.base}/logs/application.log"
            filePattern="${sys:catalina.base}/logs/application %d{yyyy-MM-dd}.log"
            append="false">
              <PatternLayout>
                  <Pattern>%d{HH:mm:ss.SSS} [%t] %-5level %c{36} %l: %msg%n</Pattern>
              </PatternLayout>
              <Policies>
                  <TimeBasedTriggeringPolicy interval="1" modulate="true"/>
              </Policies>
              <DefaultRolloverStrategy/>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="my.package" level="info" additivity="false">
            <AppenderRef ref="ApplicationLog"/>
        </Logger>
        <Logger name="my.test.package" level="debug" additivity="false">
            <AppenderRef ref="Console"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

希望这能帮助其他人在不到3天的时间内解决这个问题。

编辑：所以事实证明这个属性记录在这里（表中的第一个参数），但它仍然没有意义，为什么追加是默认行为。为什么我希望我的文件大小永远增加！？反正不是重点，只是咆哮！

谢谢，亚当
