Spring Data Couchbase - map dynamic keys in a JSON document to a model class

Is there a way to map dynamic keys in a JSON document to a model class and eventually read and write this document to a Couchbase bucket using Spring Data?
One approach would be to encapsulate all dynamic fields within a key, e.g., “data”, in the document. However, are there other options or best practices for managing such dynamic structures in Couchbase with Spring Data? Any guidance would be highly appreciated.

{
  "myDynamicKey1": [
    1,
    2,
    3
  ],
  "myDynamicKey2": true,
  "myDynamicKey3": null,
  "myDynamicKey4": 123,
  "myDynamicKey5": {
    "a": "b",
    "c": "d",
    "e": "f"
  },
  "myDynamicKey6": "Hello World"
}

I think your proposed approach - an enclosing object ‘data’ which would be a JsonObject’ is the best solution. A HashMap<String,String> would work if all the values were a single concrete type such as String. But given they are String, boolean, Number, Array - that won’t work. And HashMap<String,Object> will not work because spring data doesn’t know how to create an Object from arbitrary values.
