Jackson dynamic property names

Question

I would like serialize an object such that one of the fields will be named differently based on the type of the field. For example:

public class Response {
          


        

Answer 1

Using a custom JsonSerializer.

public class Response {
  private String status;
  private String error;

  @JsonProperty("p")
  @JsonSerialize(using = CustomSerializer.class)
  private Object data;

  // ...
}

public class CustomSerializer extends JsonSerializer
