如何给你的web项目加入log4net支持

1) 下载到log4net的dll文件: log4net.dll.

    下载好后,你可以将气拷贝到web项目的bin目录,然后给你的web项目加入该文件的reference.

 

2)  配置log4net.config文件, 代码如下:

代码

<? xml version="1.0" encoding="utf-8"  ?>
< log4net  debug ="false" >
   < appender  name ="LogFileAppender"  type ="log4net.Appender.FileAppender" >
     < param  name ="File"  value ="Log/MyBlog.log" />
     < param  name ="datePattern"  value ="YY-MM-dd HH:mm" />
     < param  name ="AppendToFile"  value ="true" />
     < layout  type ="log4net.Layout.PatternLayout" >
       < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n" />
     </ layout >
   </ appender >
   < appender  name ="HttpTraceAppender"  type ="log4net.Appender.ASPNetTraceAppender" >
     < layout  type ="log4net.Layout.PatternLayout" >
       < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n" />
     </ layout >
   </ appender >
   < appender  name ="EventLogAppender"  type ="log4net.Appender.EventLogAppender" >
     < layout  type ="log4net.Layout.PatternLayout" >
       < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n" />
     </ layout >
   </ appender >
   < appender  name ="RollingLogFileAppender"  type ="log4net.Appender.RollingFileAppender" >
     < file  value ="log\MyBlog" />
     < appendToFile  value ="true" />
     < rollingStyle  value ="Date" />
     < datePattern  value ="_yyyyMMdd'.log'" />
     < staticLogFileName  value ="false" />
     < layout  type ="log4net.Layout.PatternLayout" >
       < conversionPattern  value ="%d [%t] %-5p %c - %m%n" />
     </ layout >
   </ appender >
   < root >
     < level  value ="INFO" />
     <!-- <level value="ERROR" /> -->
     < appender-ref  ref ="RollingLogFileAppender" />
   </ root >
</ log4net >

 

 

3)  配置Web.Config文件,代码如下:

代码

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

    ...

        < log4net  configSource ="log4net.config" />
        < system.web >

</ configuration >

 

 

4)  在Global.asax文件中加入如下代码:

 

代码

using log4net.Config;

 

public   class  Global : System.Web.HttpApplication
{

         protected   void  Application_Start( object  sender, EventArgs e)
        {
            XmlConfigurator.Configure();
        }
        ...
}

 

 

5)  在客户端类中按如下方法加入日志:

 

using log4net;

 

//  将logger作为类的成员变量
private   static   readonly  ILog logger  =  LogManager.GetLogger( typeof (类名));

...

logger.Info( " 信息日志 " );

logger.Error( " 错误日志 " );
