In this section, we're going to take a look at using JSON-B for marshalling and unmarshalling of your JSON and POJO data structures, how you can use JSON-B annotations on POJOs such as @JsonbProperty, @JsonbNumberFormat, @JsonbDateFormat, @JsonbTransient, and @JsonbPropertyOrder, and finally how you can explicitly create JsonbConfig and Jsonb instances using JsonbBuilder.
Let's get started and switch to code. We will create a JsonResource class. This is our basic REST resource and we want to implement our basic methods that return JSON structures from a POJO and that unmarshall our POJO from JSON structures.
The first bit is easy; first up, we're implementing a basic @GET method. We call it marshall and it returns a JsonbPojo. JsonbPojo is a plane POJO object: it's a plane class. We'll use the @Produces application for JSON...
