用Log4Net记录NHibernate中执行的SQL语句及执行时间

首页，在web.config中加入以下配置：

<configuration>

   <configSections>

     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

   </configSections>

   <!--log4net 配置-->

   <log4net debug="true">

     <appender name="rollingFile" type="log4net.Appender.RollingFileAppender,log4net">

       <param name="File" value="log/log.txt"/>

       <param name="AppendToFile" value="false"/>

       <param name="RollingStyle" value="Date"/>

       <param name="StaticLogFileName" value="true"/>

       <layout type="log4net.Layout.PatternLayout">

         <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

       </layout>

     </appender>

     

     <logger name="NHibernate" additivity="true">

       <level value="ERROR"/>

       <appender-ref ref="DebugAppender" />

     </logger>

     <logger name="NHibernate.SQL" additivity="true">

       <level value="DEBUG"/>

       <appender-ref ref="DebugAppender" />

     </logger>

     

     <logger name="NHibernate.AdoNet.AbstractBatcher" additivity="true">

       <level value="DEBUG"/>

       <appender-ref ref="DebugAppender" />

     </logger>

     

     <root>

       <!-- levels: DEBUG, INFO, WARN, ERROR, FATAL -->

       <level value="DEBUG"/>

       <appender-ref ref="rollingFile"/>

     </root>

   </log4net>

 </configuration>

然后，在Global.asax加入以下代码并添加相应引用：

 1 private static log4net.ILog logger = log4net.LogManager.GetLogger("Logger");

 2 

 3 private static readonly ILog applicationInfoLog = LogManager.GetLogger("ApplicationInfoLog");

 4 

 5 protected override void Application_Start(object sender, EventArgs e)

 6 {

 7 //初始化log4net

 8 log4net.Config.XmlConfigurator.Configure();

 9 

10 base.Application_Start(sender, e);

11 

12 }
