Request process lifecycle of Spring MVC by R4R Team

Request process lifecycle of Spring MVC:-

The Spring Web model-view-controller (MVC) framework is designed around a DispatcherServlet that handles all the HTTP requests and responses.

(OR)

Spring’s web MVC framework is, like many other web MVC frameworks, request-driven, designed around a central Servlet that dispatches requests to controllers and offers other functionality that facilitates the development of web applications.The request processing workflow of the Spring Web MVC DispatcherServlet is as follows:
 

Following is the Request process lifecycle of Spring MVC:

1 The client sends a request to web container in the form of http request.

2 The 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.
