How Spring MVC inherits AbstractController classes

This article is about how Spring MVC inherits the AbstractController class. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Inherit the AbstractController class

If you want to easily control the supported HTTP methods, sessions, and content caches, it is ideal to have the control class inherit the AbstractController class. Such as:

Import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; publicclassBigControllerextends AbstractController {@ Override protected ModelAndView handleRequestInternal (HttpServletRequest request, HttpServletResponse response) throws Exception {System.out.println ("You're big!"); returnnew ModelAndView ("big");}}

The above example creates a single-action controller configured with supported methods, sessions, and caches that can be indicated in the controller's bean declaration. Such as:

This configuration indicates that the controller handler method only supports the POST method. For more configuration (such as sessions, caching), see AbstractController.

SpringMVC also provides several controller classes that support specific purposes, including:

AbstractUrlViewController

MultiActionController

ParameterizableViewController

ServletForwardingController

ServletWrappingController

UrlFilenameViewController
