Its case of deep serialization. You need right object structure to accommodate it.
Such as following (add getters and setters and default constructor in case you overload constructor):
Class Dictionary{
List<Words> words;
Class Words {
String name;
String level;
}
}
While initialize serializer use something like :
jsonSerializer.include("words");
jsonSerializer.include("words.*");
