Building a hypermedia-driven RESTful Java microservice using Hypermedia as the Engine of Application State (HATEOAS)

Learn how to utilize Hypermedia as the Engine of Application State (HATEOAS) to power your RESTful web application using Open Liberty. Learn how to make use of hypermedia to build an a particular style of response JSON that contains information that can be used for navigation within your REST services. The service will be built on an inventory REST service you can create using MicroProfile technology. How do you define HATEOAS? HATEOAS is a restricted version of the REST application architecture. The client is informed about available resources through an REST app. The client doesn't have to be reprogrammed to a number of resources, and the application and client are able to develop independently. The application informs the client of where it is able to travel and what resources it can access through a an easy set of hyperlinks to other sources. Response JSON In the case of HATEOAS every resource has to include a link to self, which is often called self. In this article it is noted that the JSON structure is an exchange between the hostname and the list of links to HATEOAS.
