Join Alex Theedom for an in-depth discussion in this video Solution: Add resource methods, part of RESTful Service with JAX-RS 2.0.
- [Instructor] Okay so how did you get along…with that challenge?…Well here's my solution.…In the book resource class, you can see…that I've created a method called update book.…This method has the annotation PUT…which is a TTP method we need for an update.…And I've also defined a consumes…and produces annotation as well.…Both of them will have the media type Jason.…I've also annotated the method with path…and I've passed it the regular expression…for the ISBN.…Now in the method itself,…what I've done is to pass in the…ISBN as a path parameter into the string ISBN variable…as well as the book entity.…
And the code in the method.…What this does is to call the save-book method…on the book repository.…Past to the save-book method the book entity…that's being passed into the update book method.…And then the save-book is passed back…to the calling client.…Let's have a look at the author resource.…In the author resource, we have two methods.…The first method gets a list of all…of the authors in the system.…And all this does is it cause the get all method…
