每个项目 C# 的 log4net 配置

Question

我有 3 个 Class Lib 项目（ClassLib1.dll、ClassLib2.dll、ClassLib3.dll）。一个 Windows 服务项目。 Windows服务 1.

网络日志是为 Windows 服务项目配置的，log4net 在配置文件中作为

    <log4net> 
    <root>
      <level value="all" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <file value="C:\XX\Logs\{App_Name}\{App_Name_Log_File_}" />
      <countDirection value="1" />
      <datePattern value="yyyyMMdd'.log'" />
      <staticLogFileName value="false" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%utcdate{yyyy-MM-dd HH:mm:ss,fff} %-level [%thread] [%M %C] - %message%newline" />
      </layout>
    </appender>
  </log4net>

Windows 服务引用调用 3 Class Lib 项目。我如何为这 3 个 class 库配置 log4 net，以便我可以在单独的文件夹中有一个日志文件，如下所示？

主要 windows 服务 C:\XX\Logs\Win_Servive\Win_Service_Log_File_.log 对于 Class 库 1 C:\XX\Logs\ClassLib1\ClassLib1_Log_File_.log 对于 Class 库 2 C:\XX\Logs\ClassLib2\ClassLib2_Log_File_.log 对于 Class 库 3 C:\XX\Logs\ClassLib3\ClassLib3_Log_File_.log

Answer 1

您可以通过在 web.config 文件上配置三个不同的附加程序，然后按名称加载三个不同的记录器来实现此目的：

 <appender name="Class1Appender" type="log4net.Appender.RollingFileAppender" additivity="false">....</appender>
 <appender name="Class2Appender" type="log4net.Appender.RollingFileAppender" additivity="false">....</appender>
 <appender name="Class3Appender" type="log4net.Appender.RollingFileAppender" additivity="false">....</appender>

然后使用合适的记录器：

ILog class1Log = LogManager.GetLogger("Class1Appender");
ILog class2Log = LogManager.GetLogger("Class2Appender");
ILog class3Log = LogManager.GetLogger("Class3Appender");

最终的 log4net 配置如下

<log4net>
<root>
  <level value="all" />
</root>

<logger name="WinService">
  <appender-ref ref="WinService" />
</logger>

<logger name="ClassLibrary1">
  <appender-ref ref="ClassLib1" />
</logger>

<logger name="ClassLibrary2">
  <appender-ref ref="ClassLib2" />
</logger>

<logger name="ClassLibrary3">
  <appender-ref ref="ClassLib3" />
</logger>

<appender name="WinService" type="log4net.Appender.RollingFileAppender" additivity="false">
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <file value="C:\XX\Logs\WinService\WinService_" />
  <countDirection value="1" />
  <datePattern value="yyyyMMdd'.log'" />
  <staticLogFileName value="false" />
  <appendToFile value="true" />
  <rollingStyle value="Composite" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="10MB" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%utcdate{yyyy-MM-dd HH:mm:ss,fff} %-level [%thread] [%M %C] - %message%newline" />
  </layout>
</appender>
<appender name="ClassLib1" type="log4net.Appender.RollingFileAppender" additivity="false">
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <file value="C:\XX\Logs\ClassLib1\ClassLib1_" />
  <countDirection value="1" />
  <datePattern value="yyyyMMdd'.log'" />
  <staticLogFileName value="false" />

  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%utcdate{yyyy-MM-dd HH:mm:ss,fff} %-level [%thread] [%M %C] - %message%newline" />
  </layout>
</appender>
<appender name="ClassLib2" type="log4net.Appender.RollingFileAppender" additivity="false">

  </layout>
</appender>
<appender name="ClassLib3" type="log4net.Appender.RollingFileAppender" additivity="false">
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
