With HATEOAS, a client interacts with a network application whose application servers provide information dynamically through hypermedia.

What is a hypermedia API?

Hypermedia API’s are websites. A hypermedia API wants your consuming client to surf an API, like a human surfs the web: Follow links, submit forms. A hypermedia API provides the information, so if any URL’s, actions, or needed parameters change, the consumers (API clients) can still work without being re-coded.

Should I use spring Hateoas?

3 Answers. Spring HATEOAS provides common abstractions (representational models, a Link class, API to build links pointing to Spring MVC controllers, etc.) to ease building hypermedia driven REST APIs with Spring MVC in general. Thus, you can use it alongside Spring MVC to manually build those services.

How do you implement Hateoas in rest spring boot?

To implement HATEOAS, we would need to include related resources in the response. Instead of Student we use a return type of EntityModel . EntityModel is a simple class wrapping a domain object and allows adding links to it. We create a new resource.

HATEOAS, or Hypermedia as the Engine of Application State, is a complicated-sounding term for a simple idea: A client interacts with a REST API entirely through the responses provided dynamically by the server. Put even more simply: You shouldn’t need any documentation or out-of-band information to use a REST API.

Should I use Hateoas?

HATEOAS is just one of the aspects that adds difficulty to a REST architecture. People don’t do HATEOAS for all the reasons you suggest: it’s difficult. It adds complexity to both the server side and the client (if you actually want to benefit from it). HOWEVER, billions of people experience the benefits of REST today.
