Log4net AdoNetAppender 不保存到 Db

Question

我的 AdoNetAppender 出现问题 - 只是没有记录。我浏览了 log4net 手册和其他各种链接，但看不到我做错了什么。以下是我的配置文件以及我如何调用它，因此我们将不胜感激！

您正在尝试使用存储过程将 Log4Net 日志存储在您的数据库中。 根据您所拥有的，我只能想到可能导致问题的这两件事。

1)conversionPattern 的值不正确。见下文：

   <parameter>
    <parameterName value="@HTTPMethod" />
    <dbType value="String" />
    <size value="10" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%message" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@URI" />
    <dbType value="String" />
    <size value="512" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{URI}" /> <- here use property instead of "UserID"
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@RequestData" />
    <dbType value="String" />
    <size value="1024" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{RequestData}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@UserID" />
    <dbType value="int" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{UserID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@UserToDealerID" />
    <dbType value="int" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{UserToDealerID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@AdminID" />
    <dbType value="String" />
    <size value="256" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{AdminID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@SessionID" />
    <dbType value="String" />
    <size value="256" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{SessionID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@BrowserInfo" />
    <dbType value="String" />
    <size value="1024" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{BrowserInfo}" />
    </layout>
  </parameter>

2) 如果你改成上面的代码，还是不行。考虑 log4Net 参数是否为 匹配存储过程中的参数。您可以尝试使用虚假数据并执行 Logger.Debug() 之前的任何地方的存储过程。如果有效，问题是，

 Logger.Debug(auditModel.Method);
