使用 log4net 写入两个不同的文件

Question

我想在我的应用程序中使用两个不同的记录器，这样我就能够将不同的消息记录到不同的文件中。我的 app.config 看起来像

<log4net>
<appender name="Appender1" type="log4net.Appender.RollingFileAppender">
  <file value="File1" />
  <appendToFile value="true" />
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="1MB" />
  <rollingStyle value="Composite" />
  <staticLogFileName value="false" />
  <datePattern value=".yyyy-MM-dd'.txt'" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger - %message %exception{Message} %newline" />
    <IgnoresException value="False" />
  </layout>
</appender>
<appender name="Appender2" type="log4net.Appender.RollingFileAppender">
  <file value="File2.Log"/>
  <appendToFile value="true" />
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <maxSizeRollBackups value="100" />
  <maximumFileSize value="10MB" />
  <rollingStyle value="Size" />
  <staticLogFileName value="true" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %message %newline" />
    <IgnoresException value="True" />
  </layout>
</appender>
<logger Name="Logger1" additivity="false">
  <level value="INFO"/>
  <appender-ref ref="Appender1" />
</logger>
<logger Name="Logger2" additivity="false">
  <level value="DEBUG"/>
  <appender-ref ref="Appender2" />
</logger>

在类内部，记录器的初始化如下：

private static readonly ILog Log1 = LogManager.GetLogger("Logger1");
private static readonly ILog Log2 = LogManager.GetLogger("Logger2");

我写下这些消息：

Log1.Info("Message1");
Log2.Debug("Message1");

日志文件已创建，但它们是空的。我不确定我做错了什么。

这对我有用......你可以按照你想要的方式调整模式

<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="false">

  <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/Abc.txt" />
    <appendToFile value="true" />
    <maxSizeRollBackups value="45" />
    <rollingStyle value="Date" />
    <datePattern value="yyyyMMdd" />
    <staticLogFileName value="true" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%ndc] %line - %message%newline" />
    </layout>
  </appender>
  <root>
    <level value="All" />
    <appender-ref ref="RollingLogFileAppender" />
  </root>

  <!--For Call BAck  Only-->
  <appender name="Summary" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/Callback.txt" />
    <appendToFile value="true" />
    <maxSizeRollBackups value="45" />
    <rollingStyle value="Date" />
    <datePattern value="yyyyMMdd" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%ndc] %line - %message%newline" />
    </layout>
  </appender>

  <logger additivity="false" name="Summary">
    <level value="DEBUG"/>
    <appender-ref ref="Summary" />
  </logger>


  <!--One More Log-->
  <appender name="Quartz" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/Quartz.txt" />
    <appendToFile value="true" />
    <maxSizeRollBackups value="45" />
    <rollingStyle value="Date" />
    <datePattern value="yyyyMMdd" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%ndc] %line - %message%newline" />
    </layout>
  </appender>

  <logger additivity="false" name="Quartz">
    <level value="DEBUG"/>
    <appender-ref ref="Quartz" />
  </logger>

</log4net>
