An overview of the Spring MVC request flow
The Spring MVC request flow in short:
- 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.
- The dispatcher servlet determines a suitable controller that is capable of handling the request and dispatching this request to the controller.
- The controller method updates objects in the model and returns the logical view name and updated model to the dispatcher servlet.
- The dispatcher servlet consults with the view resolver to determine which view to render and passes the model data to that view.
- 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.
- At the end, the dispatcher servlet returns the final, rendered page as a response to the browser.
