Answer
It promotes modularity and maintainability.
Separating concerns ensures that each layer of your application has a distinct responsibility: @RestController manages HTTP requests, @Service handles business logic, and @Repository deals with data access. This modular approach makes the code easier to maintain and test. For example, in an e-commerce application, a @RestController could handle a 'place order' HTTP request, the @Service could process the order logic, and the @Repository could update the database.
