What is Spring MVC?

It helps in the development of web applications by considering the Model-View-Controller (MVC) architectural pattern. It offers a structured approach to the code design, also promoting the creation of robust and scalable web applications. The core of the Spring MVC Framework is the Dispatcher Servlet which helps in the functioning as the Front Controller by managing the incoming HTTP requests by directing them to the relevant controller.

Some annotations like @Controller and @RequestMapping, the framework that shows a clear structure. @Controller represents a class as a controller, while @RequestMapping represents web requests with corresponding methods in the Spring Controller. This pattern follows the MVC architecture:

• Model: It represents the encapsulation of the application data.
• View: It renders the model data and generates the HTML output for the client’s browser.
• Controller: It processes user requests and forwards them to the view for rendering the data in response data with some specified format.

Features

1. MVC Architecture

• It follows the Model-View-Controller (MVC) pattern which promotes a modular and organized structure for building web applications.
• It provides a lot of in-built annotations which reduces the code length and helps to build scalable software applications.

2. Annotation-Based Configuration

• It supports the use of annotations for configuration which reduces the XML-based configuration.
• It makes the development more accurate.

3. Powerful Data Binding

• It has robust data binding capabilities which simplifies the handling of such formed data.
• It makes more easier to bind the incoming requests in a single unit within the Java objects.

4. Flexible Handler Mapping

• It maps incoming requests to the appropriate controller methods.
• It maps based on various criteria such as URL patterns, HTTP methods, headers, and parameters which provides flexibility in request handling.
