This brings us to the end of this Spring MVC tutorial. Even in the present era, Spring is still relevant and it is advisable to learn and get knowledge through Spring MVC Spring MVC Framework follows the Model-View-Controller design pattern. It is used to develop web applications. It works around DispatcherServlet. DispatcherServlet handles all the HTTP requests and responses. It dispatches the requests to handlers.
