Introduction to Spring MVC

Spring MVC (Model-View-Controller) is a framework for building web applications in the Java platform. It provides a flexible and modular architecture for developing web applications, and it is part of the larger Spring Framework.

Spring MVC is based on the Model-View-Controller design pattern, which separates the application into three main components:

1. Model: The model represents the data and business logic of the application. It holds the data that needs to be displayed in the view.

2. View: The view is responsible for rendering the model data and presenting it to the user. In Spring MVC, the view is typically a JSP page or a template engine like Thymeleaf.

3. Controller: The controller handles user input and updates the model and view accordingly. It acts as an intermediary between the model and the view.

In Spring MVC, the request handling is performed by the DispatcherServlet, which acts as the front controller and dispatches requests to the appropriate controllers. The controllers are annotated with the @Controller annotation and implement the request handling methods that handle the incoming requests and return the appropriate response.
