定义异常捕获类:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class ExceptionAttribute : FilterAttribute, IExceptionFilter
{
public virtual void OnException(ExceptionContext filterContext)
{
string message = string.Format("消息类型:{0}<br>消息内容:{1}<br>引发异常的方法:{2}<br>引发异常源:{3}"
, filterContext.Exception.GetType().Name
, filterContext.Exception.Message
, filterContext.Exception.TargetSite
, filterContext.Exception.Source + filterContext.Exception.StackTrace
); //记录日志
WriteLog.WriteInfo(message); //抛出异常信息
filterContext.Controller.TempData["ExceptionAttributeMessages"] = message; //转向
filterContext.ExceptionHandled = true;
filterContext.Result = new RedirectResult(Globals.ApplicationDirectory + "/Error/ErrorDetail/");
}
}
Mvc全局使用异常捕获类:
Global.asax.cs文件注册全局异常捕获类
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new Models.ExceptionAttribute());
filters.Add(new HandleErrorAttribute());
}
实现其他全局过滤的思想同上.
