Join Alex Theedom for an in-depth discussion in this video Inheritance or XML configuration, part of RESTful Service with JAX-RS 2.0.
- As we have seen in previous videos…the resources represented by a URL are made up of…the domain, context name space,…followed by the base URI for the application path,…and then the resource name.…How do you define the base URI?…There are two ways to make this configuration:…By inheritance, and in the deployment descriptor.…So by inheritance you create a class which…subclasses the application class,…which is then annotated application path.…The name of the base URI is past the annotation.…
Alternatively, by specifying the URL pattern for…the servlet mapping in the application's web.xml file.…OK let's examine both of these methods…in a little more detail.…If you choose the inheritance configuration route,…you would need a minimum of one application path defined…within your application, although it is perfectly legal and…quite common to have more.…This is the manner in which we are going to configure…the bookshop application.…I will show you how to do this in just a moment.…If you choose the deployment descriptor path,…
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.
