Как определить пользовательский тип данных в JSON

{
  "type": "Person",
  "name": "John",
  "age": 30
}

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "type")
@JsonSubTypes({
    @JsonSubTypes.Type(value = Person.class, name = "Person"),
    @JsonSubTypes.Type(value = Animal.class, name = "Animal")
})
public abstract class Entity {
    private String type;
    // getters/setters
}

public class Person extends Entity {
    private String name;
    private int age;
    // getters/setters
}
