Jackson Deserialisation Unrecognised Property issue on Nested Object

Question

I have a Nested object which is mapped with json data. My object structure is as follows:

@JsonIgnoreProperties(ignoreUnknown = true)
public class Result {

  public final int status;

  public final int data;

  @JsonProperty("error")
  public final ErrorDetail errorData;

  /** Error Detail */
  public static class ErrorDetail {
    public final int code;
    public final String category;
    public final String message;
    public final String details;
}
// Respective Getters & Setters
}

My Json data looks like:

{
  "status": 1,
  "http_code": 400,
  "data": 123,
  "error": {
    "code": 1001,
    "category": "hello world",
    "message": "Hello world",
    "detail": null
  }
}

Here as in json error section we are sending detail which is an unknown field so it should be ignored.

Note: json error section detail and Java Object ErrorDetail details are different and not related.
