Different types of MVC action filters are.
Ans: The errors are handled by the concept of exception handling either it is a windows form or even a web application. The HandlerError attribute helps in providing the built-in exception filters. The HandleError attribute of ASP.NET is functional over the action method as well as Controller at its global level.
Example:
public static void RegGlobalFilters(Global_FilterCollection filt)
{
filt.Add(new HandleErrorAttribute());
}
protected void Application_Start()
{
AreaRegn.RegisterAllAreas();
RegGlobalFilters(Global_Filters.Filters);
RegisterRoutes(Route_Table.Routes);
}
Ans: It is a java framework used for creating web applications. Spring MVC follows the MVC design patterns which use the basic features of a core spring framework including the dependency injection, inversion of control etc.
