asp.net – 如何在SQL4的log4net配置中使用存储过程进行日志记录

如何更新存储过程的commandText和参数部分,以便我可以通过log4net将错误记录到SQL Server中？

我正在使用SQL Server 2008,我的appender配置如下所示：

<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
  <bufferSize value="100"/> 
  <connectionType value="System.Data.SqlClient.SqlConnection,System.Data,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089"/> 
  <connectionString value="server=MYSERVER; uid=MYUSER; pwd=MYPASS; database=MYDB"/> 
  <commandText 
    value="INSERT INTO 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>

解决方法

<commandText value="StorProcName" />
 <commandType value="StoredProcedure" />

 <parameter>
    <parameterName value="@log_date" />
    <dbType value="DateTime" />
    <layout type="log4net.Layout.RawTimeStampLayout" />
 </parameter>
 ... all parameters ...

log4net online config examples page：

The
CommandText is either a prepared statement or a stored procedure. Each parameter to the prepared statement or stored procedure is specified with its name,database type and a layout that renders the value for the parameter.
