public Class History{

 // what annotation here?
 private Desc desc;
 //get, set method

 public Class Desc{

This is an issue tracker, not discussion forum. But if I understand question correctly, no, there is no automated way of doing "json in json". You could do setDesc(String str) in which you parse contents, however. Or assign custom deserializer for class Desc, or field "desc" (use @JsonDeserialize(using = MyDeserializer.class)).

Hope this helps.
