Price: Free CAD
Rating: 4.6 (54 reviews)

Explore how to access a simple RESTful web service and consume its resources in Java using JSON-B and JSON-P.

You will learn how to access a REST service, serialize a Java object that contains a list of artists and their albums, and use two different approaches to deserialize the returned JSON resources. The first approach consists of using the Java API for JSON Binding (JSON-B) to directly convert JSON messages into Java objects. The second approach consists of using the Java API for JSON Processing (JSON-P) to process the JSON.

The REST service that provides the artists and albums resources is already written for you. When the server is running, this service is accessible at the http://localhost:9080/artists endpoint, which responds with the artists.json file.

You will implement the following two endpoints using the two deserialization approaches:

…/artists/total to return the total number of artists in the JSON
…/artists/total/<artist> to return the total number of albums in the JSON for the particular artist
