Join Alex Theedom for an in-depth discussion in this video Define the REST contract, part of Java EE: RESTful Service with JAX-RS 2.0.
- [Instructor] Let's lay out the endpoint URIs…that we will be implementing in the REST API.…In the bookshop application,…there are going to be two resources:…a book resource and an author resource.…For both of these resources,…we will be defining the appropriate endpoint URIs.…These URIs, combined with the appropriate HTTP method,…URI variables, or parameters,…form the API contract with the client.…In order to be clear about the contract's terms,…we should specify what they are.…First of all, you need to define the application namespace.…
That's the route to the application.…Then, the application path to the route of the API itself.…So, for the REST server application,…the namespace for the application is rest-server…and the application path to the REST API itself is /api.…So this, then, makes the route to the REST API…rest-server/api.…The REST server application will be deployed locally…and on port 8081.…It's deployed on port 8081 so that the REST application…can be deployed on port 8080.…
So the API's full location is located at…
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.
