Get Spring Mvc Par L'exemple - Partie 2 - Serge

Model–view–controller (MVC) is a software design pattern commonly used for developing user interfaces that divides the related program logic into three interconnected elements.

LIFE CYCLE OF SPRING MVC REQUEST/RESPONSE Input goes to DispatcherServlet. Handler mapping gives the specific controller name to DispatcherServlet. DispatcherServlet calls that specific controller by passing request and response objects. Controller returns model and view.

Spring MVC – Multiple Controller In the case of Maven, load the spring jar files or add dependencies. Make your controller class. Provide a controller entry in the web. xml file. In a separate XML file, define the bean. Make the rest of the view components. Start the server and make the project available.

Spring MVC is based on Model-View-Controller architecture. Below image shows Spring MVC architecture at a high level. DispatcherServlet is the front controller class to take all requests and start processing them. We have to configure it in web. xml file.

When MVC is applied, the application is divided into three layers: Data layer or Model, UI or View and Controller. Each layer of MVC has a different function. First, The UI or View layer is the user interface. It is the main interface between the users and the application.

Spring MVC Framework follows the Model-View-Controller architectural design pattern which works around the Front Controller i.e. the Dispatcher Servlet. The Dispatcher Servlet handles and dispatches all the incoming HTTP requests to the appropriate controller.

The Model View Controller (MVC) design pattern specifies that an application consists of a data model, presentation information, and control information. The pattern requires that each of these be separated into different objects.
