Spring MVC Architecture
Discover the architecture of Spring MVC to understand how DispatcherServlet orchestrates requests through controllers, models, and views. Learn the flow of requests, configuration options, and advantages such as modularity, integration, and testability to build maintainable and flexible web applications with Spring.
We'll cover the following...
Spring MVC is a web framework built on top of the Spring Framework, providing a robust architecture for developing web applications. It follows the Model-View-Controller (MVC) architectural pattern, which separates an application into three interconnected components: Model, View, and Controller. Spring MVC uses the features of the core Spring framework like Inversion of Control (IoC) and dependency injection.
Components of Spring MVC
DispatcherServlet: Acts as the front controller for Spring MVC applications. It receives incoming requests and dispatches them to the appropriate controllers for processing.
Controller: Represents the C (Controller) in the MVC pattern. Controllers handle user requests, process input, and interact with the model to prepare data for the view.
Handler mapping: Maps incoming requests to appropriate controller methods based on configured URL patterns.
View resolver: Resolves logical view names returned by controllers to actual view implementations (e.g., JSP, Thymeleaf templates).
Model: Represents the M (Model) in the MVC pattern. It encapsulates the application's business logic and data. Controllers use models to pass data to views for rendering. ...
