解决Asp.net MVC3下Web.config开启Custom Errors后Application_Error不触发问题

1.配置文件中开启CustomErrors

 

<customErrors mode="On" defaultRedirect="~/Home/Error">  

    <error statusCode="404" redirect="~/Home/NotFound" />  

</customErrors>  

 

2.新建一个MyExceptionFilter类，实现IExceptionFilter接口

public class MyExceptionFilter : IExceptionFilter  

{  

    public void OnException(ExceptionContext context)  

    {  

         Exception ex = context.Exception;  

         if (!(ex is HttpException))   

         {  

              // 记录日志    

         }  

    }  

}  

 

3.注册过滤器

public static void RegisterGlobalFilters(GlobalFilterCollection filters)  

{  

    filters.Add(new MyExceptionFilter());    // 一定要放在 HandleErrorAttribute 之前  

    filters.Add(new HandleErrorAttribute());   // 这里拦截了Error消息，所以Application_Erro不会触发  

}
