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  
}
