Join Alex Theedom for an in-depth discussion in this video Add HATEOAS to the resource, part of Java EE: RESTful Service with JAX-RS 2.0.
- [Instructor] Okay, so let's start by creating…the link resource class.…This class represents a link to a URI endpoint,…such as self or delete.…And then create the class here in the domain.…I'm gonna call this class LinkResource.…This is a simple class and requires only three fields.…The first field is going to be called rel,…and this is the name of a logical relationship.…The next field is going to be called type…and this is going to be the HTTP method type,…so we get to post or delete.…
And the final field is going to be a URI field.…We're just going to call this URI.…Okay.…We're gonna now…add a…xmlRootElement annotation to the class…and we're going to auto generate…our getters and setters like so.…I'm also going to add…a constructor.…I'm gonna auto generate the constructor.…
What I'm going to do is make this constructor accept…a link object,…and you'll see why in a moment.…From the link object we're going to get…the data we need in order to construct…our hypermedia data.…So link…like so…and also don't forget we need a…
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.
