MVC exception Filter

MVC comes with an exception filter thatHandleErrorAttribute

1. Configure the Web. config first

Defaultredirect indicates the error page that needs to jump, mode needs to be set to ON or RemoteOnly.

Note: HandleError only handles server 500 errors, 404, 400, and so on, and if you need to define the error page separately, add < in the <customErrors><customErrors/> node. Error statuscode= "404" redirect= "internalerror.htm"/>

2. Custom Jump Error page

[HandleError (view= "testerror.htm")] placed above the controller action, the method throws an exception when it enters the defined error page
