Removed the <AppenderRef level="DEBUG" ref="fileAppender" />from root logger. Thus it started logging logs based on packages.
<AppenderRef level="DEBUG" ref="fileAppender" />从根记录器中删除了。因此它开始基于包记录日志。

From Log4J Manual:
从Log4J 手册：
Adding a specific logger for a class: (you can refer to packages here too)
为一个类添加一个特定的记录器：（你也可以在这里参考包）
<Logger name="org.apache.logging.log4j.test2" level="debug" additivity="false">
<AppenderRef ref="File"/>
</Logger>
Adding a specific appender:
添加特定的appender：
<Appender type="File" name="File" fileName="${filename}">
<Layout type="PatternLayout">
<Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
</Layout>
</Appender>
