Let's see some of the advantages of Spring MVC Framework:. The DispatcherServlet checks the entry of view resolver in the XML file and invokes the specified view component.The controller returns an object of ModelAndView.The DispatcherServlet gets an entry of handler mapping from the XML file and forwards the request to the controller.As displayed in the figure, all the incoming request is intercepted by the DispatcherServlet that works as the front controller.It is responsible to manage the flow of the Spring MVC application. Front Controller - In Spring Web MVC, the DispatcherServlet class works as the front controller.Although spring also supports other view technologies such as Apache Velocity, Thymeleaf and FreeMarker. Generally, JSP+JSTL is used to create a view page.
View - A view represents the provided information in a particular format.Here, the annotation is used to mark the class as the controller. Controller - A controller contains the business logic of an application.A data can be a single object or a collection of objects. Model - A model contains the data of the application.Here, DispatcherServlet is a class that receives the incoming request and maps it to the right resource such as controllers, models, and views. It implements all the basic features of a core spring framework like Inversion of Control, Dependency Injection.Ī Spring MVC provides an elegant solution to use MVC in spring framework by the help of DispatcherServlet.
It follows the Model-View-Controller design pattern. A Spring MVC is a Java framework which is used to build web applications.
