	Spring’s MVC module is based on front controller design pattern followed by MVC design pattern. All the incoming requests are handled by the single servlet named ''DispatcherServlet'' which acts as the front controller in Spring’s MVC module. The ''DispatcherServlet'' then refers to the HandlerMapping to find a controller object which can handle the request. ''DispatcherServlet'' then dispatches the request to the controller object so that it can actually perform the business logic to fulfil the user request. (Controller may delegate the responsibility to further application objects known as service objects). The controller returns an encapsulated object containing the model object and the view object (or a logical name of the view). In Spring’s MVC, this encapsulated object is represented by class ModelAndView. In case ModelAndView contains the logical name of the view, the ''DispatcherServlet'' refers the ViewResolver to find the actual View object based on the logical name. ''DispatcherServlet'' then passes the model object to the view object which is then rendered to the end user.
