1. What is Spring MVC framework?
Spring comes with a full-featured MVC framework for building web applications. Although Spring can easily be integrated with other MVC frameworks, such as Struts, Spring’s MVC framework uses IoC to provide a clean separation of controller logic from business objects. It also allows to declaratively bind request parameters to business objects.

2. DispatcherServlet
The Spring Web MVC framework is designed around a DispatcherServlet that handles all the HTTP requests and responses.

3. WebApplicationContext
 The WebApplicationContext is an extension of the plain ApplicationContext that has some extra features necessary for web applications. It differs from a normal ApplicationContext in that it is capable of resolving themes, and that it knows which servlet it is associated with.

4. What is Controller in Spring MVC framework?
Controllers provide access to the application behavior that you typically define through a service interface. Controllers interpret user input and transform it into a model that is represented to the user by the view. Spring implements a controller in a very abstract way, which enables you to create a wide variety of controllers.

5. @Controller annotation:
The @Controller annotation indicates that a particular class serves the role of a controller. Spring does not require you to extend any controller base class or reference the Servlet API.

6. @RequestMapping annotation
@RequestMapping annotation is used to map a URL to either an entire class or a particular handler method.
