Can you explain the role of the DispatcherServlet component in Spring MVC and its main functions?

DispatcherServlet is the central component of Spring MVC, acting as the front controller. Its main task is to receive all HTTP requests coming into the application and direct them to the appropriate handlers (controllers).

Main functions of DispatcherServlet:

• Receiving and processing incoming HTTP requests.
• Finding the suitable controller using HandlerMapping.
• Calling the controller method to handle the request.
• Processing the result (ModelAndView) and selecting the view through ViewResolver.
• Sending the formed response back to the client.

Thus, DispatcherServlet organizes the entire request processing cycle in Spring MVC, ensuring separation of concerns and flexible configuration.
