logging - RollingFile Appender Log4j2 不打印行号

Question

我正在使用具有以下依赖项的 log4j2::

   <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>

我正在使用以下配置::

    <?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，我以以下格式在控制台上获取日志

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

在滚动文件中，我得到以下模式，其中缺少行号::

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

我已经疯了，因为似乎没有什么可以打印行号我也遵循了官方的 log4j2 链接
Log4j2 Migration
但结果仍然与上面相同。如果有人有任何解决方案，请告诉我。

在这里我找到了解决方案::
Log4j2 AsyncLogger with rolling file appender not showing file line number

然后我将我的 appender 引用更改为直接指向 RollingFile 名称而不是 <Async name> ，现在可以正确显示行号。不知道为什么会发生这种情况，我会找到并很快发布原因。

所以改变了以下::

<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>
