Asp.net mvc log4net同时记录到两个文件

我有两个记录器，一个叫做NotificationLogger，另一个叫做VMPLogger。出于某种原因，无论我调用哪个记录器，它都会写入两个日志

我的web.config

  <log4net>
    <appender name="VMPLogger" type="log4net.Appender.RollingFileAppender">
      <file value="logs\vmp_" />
      <appendToFile value="true" />
      <staticLogFileName value="false" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMM'.log'" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
    <appender name="NotificationLogger" type="log4net.Appender.RollingFileAppender">
      <file value="logs\notifications_" />
      <staticLogFileName value="false" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMM'.log'" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
    <root>
      <level value="ALL" />
      <appender-ref ref="VMPLogger" />
      <appender-ref ref="NotificationLogger" />
    </root>
  </log4net>

我的测试控制器操作

    public void LogSomethingNotification()
    {
        MvcApplication.NotificationLogger.Info("Something");
    }

有人能从这个代码/配置中看出原因吗？谢谢，因为GetLogger没有appender，而是一个特定的记录器。您需要在appender中筛选要查看的记录器。在附加器中添加筛选器，以便仅记录一个记录器：

<log4net>
<appender name="VMPLogger" type="log4net.Appender.RollingFileAppender">
  <file value="logs\vmp_" />
  <appendToFile value="true" />
  <staticLogFileName value="false" />
  <rollingStyle value="Date" />
  <datePattern value="yyyyMM'.log'" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
  </layout>
  <filter type="log4net.Filter.LoggerMatchFilter">
    <loggerToMatch value="VMPLogger" />
  </filter>     
  <filter type="log4net.Filter.DenyAllFilter" />
</appender>
<appender name="NotificationLogger" type="log4net.Appender.RollingFileAppender">
  <file value="logs\notifications_" />
  <staticLogFileName value="false" />
  <appendToFile value="true" />
  <rollingStyle value="Date" />
  <datePattern value="yyyyMM'.log'" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
  </layout>
  <filter type="log4net.Filter.LoggerMatchFilter">
    <loggerToMatch value="NotificationLogger" />
  </filter>     
  <filter type="log4net.Filter.DenyAllFilter" />
</appender>
<root>
  <level value="ALL" />
  <appender-ref ref="VMPLogger" />
  <appender-ref ref="NotificationLogger" />
</root>

这是因为GetLogger不获取appender，而是获取特定的记录器。您需要在appender中筛选要查看的记录器。在附加器中添加筛选器，以便仅记录一个记录器：

<log4net>
<appender name="VMPLogger" type="log4net.Appender.RollingFileAppender">
  <file value="logs\vmp_" />
  <appendToFile value="true" />
  <staticLogFileName value="false" />
  <rollingStyle value="Date" />
  <datePattern value="yyyyMM'.log'" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
  </layout>
  <filter type="log4net.Filter.LoggerMatchFilter">
    <loggerToMatch value="VMPLogger" />
  </filter>     
  <filter type="log4net.Filter.DenyAllFilter" />
</appender>
<appender name="NotificationLogger" type="log4net.Appender.RollingFileAppender">
  <file value="logs\notifications_" />
  <staticLogFileName value="false" />
  <appendToFile value="true" />
  <rollingStyle value="Date" />
  <datePattern value="yyyyMM'.log'" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
  </layout>
  <filter type="log4net.Filter.LoggerMatchFilter">
    <loggerToMatch value="NotificationLogger" />
  </filter>     
  <filter type="log4net.Filter.DenyAllFilter" />
</appender>
<root>
  <level value="ALL" />
  <appender-ref ref="VMPLogger" />
  <appender-ref ref="NotificationLogger" />
</root>
