Answer from AI
DispatcherServlet is the central component in the Spring MVC architecture responsible for handling all incoming HTTP requests.
Its role and purpose:
- Receives requests from clients and directs them to the appropriate controllers.
- Performs routing of requests based on URL and configuration.
- Manages the request lifecycle, including invoking controllers, handling exceptions, and selecting the view.
- Integrates with other Spring components such as handlers, interceptors, and resolvers.
Example: When a request is made to /users, the DispatcherServlet determines which controller and method should handle this request, invokes them, and returns the generated response to the client.
