RollingFile追加程序Log4j2不打印的行號

Question

我使用log4j2具有以下依賴::

<dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-api</artifactId> 
     <version>2.0-rc1</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-core</artifactId> 
     <version>2.0-rc1</version> 
    </dependency> 

我使用下面的配置::

<?xml version="1.0" encoding="UTF-8"?> 
<Configuration status="WARN"> 

    <Properties> 
     <Property name="LOGGER_HOME">/logs</Property> 
    </Properties> 

    <Appenders> 

     <RollingFile name="application" fileName="${LOGGER_HOME}/application.log" 
      filePattern="${LOGGER_HOME}/application.%d{yyyy-MM-dd}_%i.log"> 

      <PatternLayout pattern="%d{ISO8601}{GMT} %-5p %C{2} (%F:%L) - %m%n" /> 
      <Policies> 
       <TimeBasedTriggeringPolicy /> 
       <SizeBasedTriggeringPolicy size="1 GB" /> 
      </Policies> 

     </RollingFile> 

     <RollingFile name="framework" fileName="${LOGGER_HOME}/em-logs/framework.log" 
      filePattern="${LOGGER_HOME}/framework.%d{yyyy-MM-dd}_%i.log"> 

      <PatternLayout pattern="%d{ISO8601}{GMT} %-5p %C{2} (%F:%L) - %m%n" /> 
      <Policies> 
       <TimeBasedTriggeringPolicy /> 
       <SizeBasedTriggeringPolicy size="1 GB" /> 
      </Policies> 
     </RollingFile> 

     <Console name="out" target="SYSTEM_OUT"> 
      <PatternLayout pattern="%d{ISO8601}{GMT} %-5p %C{2} (%F:%L) - %m%n" /> 
     </Console> 

     <Async name="asyncApplication"> 
      <AppenderRef ref="application" /> 
     </Async> 

     <Async name="asyncFramework"> 
      <AppenderRef ref="framework" /> 
     </Async> 


    </Appenders> 


    <Loggers> 

     <Logger name="com.memorynotfound.logging" level="debug" 
      includeLocation="true"> 
      <AppenderRef ref="asyncApplication" /> 
     </Logger> 

    <Root level="debug" includeLocation="true"> 
      <AppenderRef ref="asyncApplication"></AppenderRef> 
     </Root> 

     <Logger name="org.axonframework" level="info" additivity="false" 
      includeLocation="true"> 
      <AppenderRef ref="asyncFramework" /> 
     </Logger> 

     <Root level="error" includeLocation="true"> 
      <AppenderRef ref="out" /> 
     </Root> 

    </Loggers> 


</Configuration> 

但是我在控制檯上獲取日誌以下格式

2015-08-20 14:29:41,613 DEBUG logging.LoggerExample (LoggerExample.java:11) - This will be printed on debug 

而在滾動文件中，我得到以下模式，其中t他行號丟失::

2015-08-20 14:29:41,613 DEBUG ?() - This will be printed on debug 

我已經堅果如無物似乎打印的行號工作，我也跟着官方log4j2鏈接 Log4j2 Migration 但還是結果同上。如果任何人有任何解決方案，請讓我知道。

在這裏，我找到了解決辦法:: Log4j2 AsyncLogger with rolling file appender not showing file line number

然後，我改變了我的appender參考直接指向RollingFile名稱，而不是<Async name>，它現在可以正確顯示的行數。不知道爲什麼會發生這種情況，我會盡快找到原因。

所以改變後::

<Logger name="com.memorynotfound.logging" level="debug" 
      includeLocation="true"> 
      <AppenderRef ref="asyncApplication" /> 
     </Logger> 

到

<Logger name="com.memorynotfound.logging" level="debug" 
     includeLocation="true"> 
     <AppenderRef ref="application" /> 
    </Logger>
