Following is the Request process lifecycle of Spring 3.0 MVC:
1 The client sends a request to web container in the form of http request.
2 This incoming request is intercepted by Front controller (DispatcherServlet)
and it will then tries to find out appropriate Handler Mappings.
3 With the help of Handler Mappings, the DispatcherServlet will dispatch
the request to appropriate Controller.
4 The Controller tries to process the request and returns the Model and
View object in form of ModelAndView instance to the Front Controller.
5 The Front Controller then tries to resolve the View (which can be JSP,
Freemarker, Velocity etc) by consulting the View Resolver object.
6 The selected view is then rendered back to client.
