The figure below shows the flow of request in the Spring MVC Framework.
When a request is sent to the Spring MVC Framework the following sequence of events happen.
The DispatcherServlet first receives the request.
The DispatcherServlet consults the HandlerMapping and invokes the Controller associated with the request.
The Controller process the request by calling the appropriate service methods and returns aModeAndView object to the DispatcherServlet. The ModeAndView object contains the model data and the view name.
The DispatcherServlet sends the view name to a ViewResolver to find the actual View to invoke.
Now the DispatcherServlet will pass the model object to the View to render the result.
The View with the help of the model data will render the result back to the user
