Please give me an idea of how to build the structure of Java objects for deserialization of this Json. I ask you not to offer generators from the Internet (they cannot generate correct objects due to the Json structure).

  "objects" : {
    "Incident::123456" : {
      "code" : 0,
      "message" : "",
      "class" : "Inc",
      "key" : "1036022",
      "fields" : {
        "id" : "1654321",
        "title" : "title"
      }
    },
    "Incident::1046077" : {
      "code" : 0,
      "message" : "",
      "class" : "Inc",
      "key" : "1046077",
      "fields" : {
        "id" : "1654322",
        "title" : "title"
      }
    }
  },
  "code" : 0,
  "message" : "Found: 2"
}

The objects that come (like “”Incident::”) have different values, their number can be infinitely large.

For each POJO, the fields of interest are in “fields” : {}

At first glance, the problem seems trivial to me, but I have not yet been able to solve it.
Is there a sane solution for such a structure? Could it be the right decision to create custom functionality?

As a result, I need to get a list of objects like:

public class Test {
    private int id; \ from "fields" : {"id" : "1654322"}
    private String title; \ from "fields" : {"title" : "title"}
}

Thank you.
