- [Instructor] Okay, so how do we…implement HATEOAS and JAX-RS?…Well, there are two ways.…The first way is to do…exactly what I've explained before,…which is to add those links…to the resource, itself.…But there is an alternative way…to communicate those links to the client.…And that is to add them to…the HTTP header of the response.…This is actually the easiest way…to HATEOAS enable your API.…So, let's look at how to do this.…So, in both cases,…the code that adds the links to the resource…is located in the entity resource class,…in the method that…actually responds to the request.…
So, JAX-RS provides a nice build to API…that constructs links to resources called link.…So, from the link class,…call the from URI method…and pass it a reference to the base URI.…This is obtained by injecting…the current request context URI info…and from this we call…the get base URI builder method.…From here, we call the path method…and pass it the current class.…This reads the path URI for the current class.…Then we pass it the class…and the actual method name in that class…
Join Alex Theedom as he guides you through a wide range of topics, including how to define resource endpoints, how to add dynamism to your application with hypermedia, how to maintain data integrity with Bean Validation, and how to process messages with the JSON Processing API. Once you have completed this course, you'll be ready to develop your own client and server RESTful APIs.
