1. What is Spring MVC?

Spring MVC is a universal design pattern used for developing applications with coupling.

It is available in the Spring framework and is used to create web-based and distributed applications.

Spring MVC is designed to provide clear roles for components, form binding object support, and simplify application development by delivering configurations for developers.

2. What are the components of Spring MVC?

The components available in the Spring MVC module include the front controller, which is responsible for handling requests.

The view, which is responsible for rendering the response; the handler mappers, which map requests to controllers.

The controller, which controls the logic of the application, the model, which holds the data, and the view resolver, which resolves the view to be rendered.

3. What is the front controller in Spring MVC?

The front controller is responsible for handling requests in a Spring MVC application.

It captures form data such as requests at gate parameters and forwards them to the appropriate controller. The front controller also handles security and authentication.

4. What is the request execution flow in a Spring MVC application?

The request execution flow in a Spring MVC application starts with the front controller receiving the request and forwarding it to the appropriate controller.

The controller then processes the request and retrieves the data from the model.

The controller then returns a view that displays the data to the user. The view resolver then resolves the view to be rendered and renders the view.

Finally, the view sends the response back to the front controller.

5. What is the architecture of Spring MVC?
