Log4net与Entity Framework 5和MVC4

Question

所以我开始这个新项目,并希望使用Log4net登录数据库.我正在使用EF进行其他事情并且连接正常.出于某种原因,L4N没有记录任何内容,但没有抛出任何错误.只是想知道我可能缺少哪些步骤,希望有人可以指出.我需要以某种方式"保存"到数据库吗？Thanx提前这么多.

我的web.config:

<log4net> 
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
  <bufferSize value="100" />
  <connectionType value="System.Data.EntityClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  <connectionString value="data source=myserver;initial catalog=Reporting;integrated security=false;persist security info=True;User ID=myid;Password=mypassword" />
  <commandText value="INSERT INTO [myschema].[Log] ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
  <parameter>
    <parameterName value="@log_date" />
    <dbType value="DateTime" />
    <layout type="log4net.Layout.RawTimeStampLayout" />
  </parameter>
  <parameter>
    <parameterName value="@thread" />
    <dbType value="String" />
    <size value="255" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%thread" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@log_level" />
    <dbType value="String" />
    <size value="50" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%level" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@logger" />
    <dbType value="String" />
    <size value="255" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%logger" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@message" />
    <dbType value="String" />
    <size value="4000" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%message" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@exception" />
    <dbType value="String" />
    <size value="2000" />
    <layout type="log4net.Layout.ExceptionLayout" />
  </parameter>
</appender>
<root>
  <level value="Info" />
  <appender-ref ref="LogFileAppender" />
</root>

和我的控制器:

 ...
 using log4net;
 using System.Reflection;

namespace MyNames.Controllers
{
  public class ClientController : Controller
  {    
     ReportingEntities db = new ReportingEntities();
     private readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

     public ActionResult Index()
     {  
         this.log.Debug("Sample message to log to Db");
         return View();
     }
   }
 }

编辑:所以我做了mods建议gorilly但仍然无法正常工作.刚碰巧检查输出窗口,即使我启用了调试它仍然显示这个..从这里尝试了调试建议,但没有抛出任何错误.

从我的log4net内部调试文件:

Answer 1

将此行添加到Global.asax.cs(在Application_Start()中):

log4net.Config.XmlConfigurator.Configure();

此外,您可以打开log4net调试,通过将此行添加到Web.config下来帮助您找出问题<appSettings>:

编辑:下面有value="false",但应该是value="true".

<add key="log4net.Internal.Debug" value="true"/>

编辑:

您可以通过将以下内容添加到Web.config中来将log4net的内部调试日志记录发送到文件中(请参阅此处的官方说明):

  <system.diagnostics>
    <trace autoflush="true">
      <listeners>
        <add
            name="textWriterTraceListener"
            type="System.Diagnostics.TextWriterTraceListener"
            initializeData="C:\mylogdirectory\log4net_debug.txt" />
      </listeners>
    </trace>
  </system.diagnostics>
