Mixing structured and un-structured data with JSON-B / JSON-P, JAX-RS and Java EE 8 📎

A JSON-B DTO with dynamic JSON-P object:


import javax.json.JsonObject;    
public class Attendee {

    public String firstName;
    public String lastName;

    public long age;

    public JsonObject profile;

    @Override
    public String toString() {
        return "Attendee{" + "firstName=" (...) profile=" + profile + '}';
    }

}

Is marshalled by JAX-RS without any additional configuration:


import com.airhacks.attendees.entity.Attendee;
import javax.ws.rs.POST;
import javax.ws.rs.Path;

@Path("attendees")
public class AttendeesResource {

    @POST
    public void registry(Attendee attendee) {
        System.out.println("attendee = " + attendee);
    }

}

The command:

url -i -XPOST -H'Content-type: application/json' -d"@attendee.json" http://localhost:8080/jsonp-with-jsonb/resources/attendees

with the payload (file attendee.json):


{
    "firstName": "duke",
    "lastName": "java",
    "age": 21,
    "profile": {
        "languages": ["java", "javascript"],
        "size": 10,
        "kind": "alien"
    }
}

yields:


attendee = Attendee{firstName=duke, lastName=java, age=21, profile={"languages":["java","javascript"],"size":10,"kind":"alien"}}]]

in the server log.
