Join Alex Theedom for an in-depth discussion in this video Implement a client, part of RESTful Service with JAX-RS 2.0.
- [Narrator] We will start with a book service…and implement a method that retrieves a catalog…of books from the rest server.…Now you will remember, the URI for a list of books…is rest-serverapibooks, and the ATT method is get.…But before we continue, let's have a look…at what this class already has in it.…Here you will see that we have an…initialize method, annotated PostConstruct.…This method will be provoked when…the book service bin is constructed by the container.…The purpose of this method is to construct a client,…and to ensure that it is constructed…before any calls are made to its methods.…
Also, you will see that I have hard-coded…the rest server's URI and the location…of the book resource.…This is just for convenience when writing…the server's methods.…You can also see a PreDestroy annotation…on the method that closes the client connection.…This is called when the client instance is destroyed,…and will cleanly close the client API.…The other methods that you see here…are methods from the interface that we'll be…
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.
