Spring MVC(一)

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
