Log4j2 AsyncLogger with rolling file appender not showing file line number
提问by Lynx777
Im using log4j2 with following dependencies:
我使用具有以下依赖项的 log4j2：
<!-- LOG4J2 -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.0-rc1</version>
</dependency>

Log4j2.xml 内容：
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="OFF">

<!-- Generate rolling log for router with per hour interval policy -->
<RollingFile name="ProcessorRollingFile" fileName="D:/ocsprocessor.log"

</PatternLayout>
<Policies>

</Policies>
<DefaultRolloverStrategy max="24" />
</RollingFile>
<!-- Register Async appender -->
<Async name="AsyncRollingFile">
<AppenderRef ref="ProcessorRollingFile" />
</Async>
</Appenders>
<Loggers>
<AsyncLogger name="com.tritronik.logger.log4j2" level="error"
additivity="false">
<AppenderRef ref="AsyncRollingFile" />
</AsyncLogger>
</Loggers>
</Configuration>
Turn out that everything went fine except the log doesn't show Line number of throwed logger (the %L in pattern).
结果一切都很好，除了日志没有显示抛出的记录器的行号（模式中的 %L）。
I googled and found out that for async logger and rolling file appender, there is no one mentioned using %L, so how can i achieved it then? Or is it doesn't support %L?
我搜索了一下，发现对于异步记录器和滚动文件附加器，没有提到使用 %L，那么我该如何实现呢？还是它不支持 %L？
Edit: I have tried added includeLocation="true", but still same results
编辑：我尝试添加includeLocation="true"，但结果仍然相同

First, remove the Async appender, and point the appender-ref of the AsyncLogger to the ProcessorLoggingFile directly. Second, you must add includeLocation="true" on the AsyncLogger.
首先，移除Async appender，将AsyncLogger的appender-ref直接指向ProcessorLoggingFile。其次，您必须在 AsyncLogger 上添加 includeLocation="true"。
Having an async appender in addition to an async logger does not help and in this case might be what prevents the includeLocation from working correctly.
除了异步记录器之外还有一个异步附加器并没有帮助，在这种情况下可能会阻止 includeLocation 正常工作。
