- [Instructor] We have already seen how the client API…can deserialize the response from the rest end-point,…directly to an object such as a response object or a list.…The API takes care of processing the JSON object…into an object that we want,…and saves us from the messy deserialization code.…But what if we want to get messy?…Or have to, because we don't know the shape of the response?…Or, simply, we want a low-level way…to access the restful API's response?…Well, we can.…The JAX-RS API works perfectly well…with adjacent processing API,…allowing us to write code that accesses the root nodes…of the JSON string,…in an intuitive, object-orientated way.…
The JSON API parses and transforms JSON data,…and also provides a way to query the data…using one of the two models:…The object model, and the streaming model.…I won't go into much detail about this right now,…as there is a specific course dedicated to this topic.…However, I will show you how to use the object model…to handle the response from the bookshop rest API.…
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.
