Enum (de)serialization in conjunction with JsonFormat.Shape.NUMBER_INT

[kistlers]

The following example is taken from StackOverflow, an answer by user SomethingSomething:

public enum State {

    @JsonProperty("0")
    OFF,

    @JsonProperty("1")
    ON,

    @JsonProperty("2")
    UNKNOWN
}

The enum State in the following POJO would be serialized as {"state": "1"}, all good so far.

public record Pojo {
    @JsonProperty("state") State state
}

However, consider the following case:

public record Pojo(
    @JsonFormat(shape = JsonFormat.Shape.NUMBER_INT) @JsonProperty("state") State state
) {}

I would like to see this case result in JSON such as {"state": 1}, with the value being a number (int in that case) instead of a string.

I would like to see something like that be supported in some way or form.

Interesting. There is no way to make that work currently but I can see how logically it would make sense.

I would suggest filing a feature request for jackson-databind (repo where it'd fit).
