web端log4net输出错误日志到mysql

1.引用log4net

2.配置log4net.config文件

 <?xml version="1.0" encoding="utf-8" ?>
 <configuration>
   <!-- Author:GaoBingBing-->
   <configSections>
     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
   </configSections>
   <log4net>
     <!--写入到数据库-->
     <appender name="AdoNetAppender_MySql" type="log4net.Appender.AdoNetAppender">
       <!--错误队列数据达到5个才持久化到数据库-->
       <bufferSize value="" />
       <param name="ConnectionType" value="MySql.Data.MySqlClient.MySqlConnection, MySql.Data"/>
       <param name="ConnectionString" value="server=localhost;database=test;Uid=sa;Pwd=sa;old syntax=yes"/>
       <commandText value="INSERT INTO log(log_datetime,log_thread,log_level,log_logger,log_message) VALUES (@log_date, @thread, @log_level, @logger, @message)"/>
       <parameter>
         <parameterName value="@log_date"/>
         <dbType value="DateTime"/>
         <layout type="log4net.Layout.RawTimeStampLayout"/>
         <!--<layout type="log4net.Layout.PatternLayout" value="%date{yyyy'-'MM'-'dd HH':'mm':'ss}" />-->
       </parameter>
       <parameter>
         <parameterName value="@thread"/>
         <dbType value="String"/>
         <size value=""/>
         <layout type="log4net.Layout.PatternLayout">
           <conversionPattern value="%thread"/>
         </layout>
       </parameter>
       <parameter>
         <parameterName value="@log_level"/>
         <dbType value="String"/>
         <size value=""/>
         <layout type="log4net.Layout.PatternLayout">
           <conversionPattern value="%level"/>
         </layout>
       </parameter>
       <parameter>
         <parameterName value="@logger"/>
         <dbType value="String"/>
         <size value=""/>
         <layout type="log4net.Layout.PatternLayout">
           <conversionPattern value="%logger"/>
         </layout>
       </parameter>
       <parameter>
         <parameterName value="@message"/>
         <dbType value="String"/>
         <size value=""/>
         <layout type="log4net.Layout.PatternLayout">
           <conversionPattern value="%message"/>
         </layout>
       </parameter>
       <!--<parameter>
         <parameterName value="@exception"/>
         <dbType value="String"/>
         <size value=""/>
         <layout type="log4net.Layout.ExceptionLayout"/>
       </parameter>-->
     </appender>
     <root>
       <level value="ALL"/>
       <appender-ref ref="AdoNetAppender_MySql"/>
     </root>
     <logger name="*">
       <level value="ALL" />
       <appender-ref ref="AdoNetAppender_MySql" />
     </logger>
   </log4net>
 </configuration>

2.项目启动处 Global.asax

log4net.Config.XmlConfigurator.Configure();

3.AssemblyInfo.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

4.创建log.cs

  //获取实例
     private static log4net.ILog myLogger = log4net.LogManager.GetLogger(Log4NetConfig.MySql);

     //错误级别:Info
     public static void Info(string message)
     {
         myLogger.Info(message);
     }
     //错误级别:Debug
     public static void Debug(string message)
     {

         myLogger.Debug(message);
     }
     //错误级别:Warn
     public static void Warn(string message)
     {

         myLogger.Warn(message);
     }
     //错误级别:Fatal
     public static void Fatal(string message)
     {

         myLogger.Fatal(message);
     }
     //错误级别:Error
     public static void Error(string message)
     {

         myLogger.Error(message);
     }

5.调用log4net

log4net.ILog myLogger = log4net.LogManager.GetLogger("message");

myLogger.Info("hello!");

简单四步配置成功第一次写博客园，还没有掌握好看的布局，再接再厉！嘻嘻
