Log4net配置检查点

1. 有引用log4net.dll

2. 有配置文件，Web.config或log4net.config

3. 有section节

   <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
     <configSections>
       <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
       <sectionGroup name="system.web">
           <section name="logService" type="OilDigital.CGGL.BLL.LogServiceSection, OilDigital.CGGL.BLL.Common" allowDefinition="MachineToApplication" restartOnExternalChanges="true"/>
   

   有system.web节，同时确保logProviderWithLog4Net中的enabled为true

     <system.web>
       <logService defaultProvider="logProviderWithLog4Net">
         <providers>
           <add name="logProviderWithLog4Net" type="OilDigital.CGGL.BLL.Log.LogProviderWithLog4Net,OilDigital.CGGL.BLL.Log" enabled="true" loggingUserName="false" loggerName="OperationLogger"/>
         </providers>
       </logService>
   

   有log4net节

   <log4net>
       <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
         <file value="Logs\opeartions-"/>
         <appendToFile value="true"/>
         <rollingStyle value="Date"/>
         <datePattern value="yyyy-MM-dd&quot;.log&quot;"/>
         <maximumFileSize value="10MB"/>
         <staticLogFileName value="false"/>
         <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
         <layout type="log4net.Layout.PatternLayout">
           <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
         </layout>
       </appender>
       <logger name="OperationLogger">
         <level value="INFO"/>
         <appender-ref ref="LogFileAppender"/>
       </logger>
     </log4net>
   

4. Global.asax的Application_Start方法中有初始化

               //初始化log4net对象
               log4net.Config.XmlConfigurator.Configure();
