Have you used Spring HATEOAS in your projects?

Spring HATEOAS is a library that simplifies the implementation of REST APIs with support for the HATEOAS (Hypermedia as the Engine of Application State) principle. It helps create responses with hypermedia links that allow clients to navigate the API dynamically.

In projects, I used Spring HATEOAS to enrich DTOs with links to related resources and actions. For example, when returning a user entity, I added links to their orders or profile, which facilitated navigation for the client.

Example of usage:

EntityModel<User> userResource = EntityModel.of(user);
userResource.add(linkTo(methodOn(UserController.class).getUserOrders(user.getId())).withRel("orders"));
return ResponseEntity.ok(userResource);

This enhances the convenience and flexibility of the API, making it more self-documenting and extensible.
