Spring MVC request flow

1. When we enter a URL in the browser, the request comes to the dispatcher servlet.
The dispatcher servlet then acts as a centralized entry point to the web application.
2. The dispatcher servlet determines a suitable controller that is capable of handling the
request and dispatching this request to the controller.
3. The controller method updates objects in the model and returns the logical view name
and updated model to the dispatcher servlet.
4. The dispatcher servlet consults with the view resolver to determine which view to
render and passes the model data to that view.
5. The view furnishes the dynamic values in the web page using the model data, renders
the final web page, and returns this web page to the dispatcher servlet.
6. At the end, the dispatcher servlet returns the final, rendered page as a response to the
browser.
