In Spring MVC, `HandlerMapping` is used to map requests to the corresponding handler. The handler can be a controller in the case of Spring MVC.

Here's a step-by-step explanation:

1. When a request comes into the Spring MVC framework, it is `DispatcherServlet` that takes the request.

2. The `DispatcherServlet` then refers to `HandlerMapping` to determine which Controller should process the request.

3. The `HandlerMapping` receives the current HTTP request as input and returns the handler execution chain. This chain includes the relevant handler object (a Controller in the case of Spring MVC) and any handler interceptors.

4. Once the `HandlerMapping` determines the appropriate Controller, the `DispatcherServlet` will send the request to that Controller.

5. The Controller then processes the request and returns a `ModelAndView` object back to the `DispatcherServlet`.

6. The `DispatcherServlet` will then send the model object to the `ViewResolver` to render the view page.

So, in summary, `HandlerMapping` is used to determine the appropriate handler for each request in Spring MVC.
