log4net 记录页眉和页脚两次

Question

这是我的配置:

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net"
       type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>

  <log4net>
    <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
      <param name="File" value="Logs\StubLog.txt" />
      <param name="AppendToFile" value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="Header" value="[Header]&#13;&#10;" />
        <param name="Footer" value="[Footer]&#13;&#10;&#13;&#10;" />
        <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" />
      </layout>
    </appender>

    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
      <layout type="log4net.Layout.PatternLayout">
        <param name="Header" value="[Header]\n" />
        <param name="Footer" value="[Footer]\n\n" />
        <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" />
      </layout>
    </appender>

    <root>
      <level value="DEBUG" />
      <appender-ref ref="LogFileAppender" />
      <appender-ref ref="ConsoleAppender" />
    </root>
    <logger name="NHibernate">
      <level value="WARN" />
    </logger>
  </log4net>

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

这是日志:

[Header]
[Footer]

[Header]
2012-10-04 14:22:01,203 [1] INFO  Stub.Program Enter application
2012-10-04 14:22:01,328 [1] DEBUG Stub.FrmMain Test
2012-10-04 14:22:03,265 [1] INFO  Stub.Program Exit application
[Footer]

第一对页眉/页脚来自哪里？我可以消除它们吗？

Answer 1

Putting XmlConfigurator.Configure() at more than one places may result in having more than one header and footer pair.

XmlConfigurator.Configure() should be defined only at one place in the solution. Better approach is to put it in AssemblyInfo.cs
