如何清除 Log4j 2.3 每日滚动文件附加器的日志
How to clear log for Log4j 2.3 daily rolling file appender
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附加器以在每晚午夜滚动。
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 application.log 文件复制到应用程序 yyyy-MM-dd.log（文件名中的日期被正确替换），并在第二天 application.log.
中继续记录
我希望在开始新的一天之前清除 application.log。目前，这还没有发生，因此我的日志大小不断增加。我的第 1 天日志包含第 1 天的所有日志记录，但我的第 2 天日志包含第 1 天和第 2 天的日志记录，依此类推。
翻转发生后如何重置 application.log 文件？根据 Log4j 2.x documentation，应该创建一个新的 application.log 文件，而不是继续当前文件，但这不是我遇到的行为。
如有任何帮助，我们将不胜感激。
谢谢，
亚当

看起来和你面对的issue一样。
检查日志文件夹的文件夹权限并授予其写入权限。
chmod 666 logs
我通过源代码调试解决了这个问题，因为我的日志本应滚动更新。
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，它将写入当前日志文件从一开始就。遗憾的是，此属性的默认值为 true，这会导致当前日志文件被附加而不是重新启动。
所以我的最终 log4j2.xml 看起来像这样：
<?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。
EDIT：结果证明这个属性被记录在here（table中的第一个参数），但它仍然没有对我来说为什么附加是默认行为是有意义的。为什么我希望我的文件大小永远增加！？反正不是重点，就是吐槽！
谢谢，

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附加器以在每晚午夜滚动。
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 application.log 文件复制到应用程序 yyyy-MM-dd.log（文件名中的日期被正确替换），并在第二天 application.log.
中继续记录我希望在开始新的一天之前清除 application.log。目前，这还没有发生，因此我的日志大小不断增加。我的第 1 天日志包含第 1 天的所有日志记录，但我的第 2 天日志包含第 1 天和第 2 天的日志记录，依此类推。
翻转发生后如何重置 application.log 文件？根据 Log4j 2.x documentation，应该创建一个新的 application.log 文件，而不是继续当前文件，但这不是我遇到的行为。
如有任何帮助，我们将不胜感激。
谢谢， 亚当

看起来和你面对的issue一样。
检查日志文件夹的文件夹权限并授予其写入权限。
chmod 666 logs
我通过源代码调试解决了这个问题，因为我的日志本应滚动更新。
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，它将写入当前日志文件从一开始就。遗憾的是，此属性的默认值为 true，这会导致当前日志文件被附加而不是重新启动。
所以我的最终 log4j2.xml 看起来像这样：
<?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。
EDIT：结果证明这个属性被记录在here（table中的第一个参数），但它仍然没有对我来说为什么附加是默认行为是有意义的。为什么我希望我的文件大小永远增加！？反正不是重点，就是吐槽！
谢谢， 亚当
