Fallback Default Value for Enum Type Field

Is your feature request related to a problem? Please describe. jackson-databind: 2.11.4

Hi, I was trying to deserialize json to Kotlin data class object which includes enum type field. But since the value of the corresponding json field is not one of the enum values, it throws InvalidFormatException

data class A(
   val type: EnumType
   ...
) : Serializable

However, I don’t need values other than the ones that are already of the enum values. So I want to set the field of the object as the default value if the value from the json does not match with any of the enum values. I think there’s no way this can be done as far as I have searched.

Describe the solution you’d like Annotation that sets default value as fallback on a field of a serialzable object

Usage example

data class A(
   @DeserializeEnumDefault(EnumType.TypeA)
   val type: EnumType
   ...
) : Serializable

@ko-ing I am very glad it worked out once you found the problem. Thank you for confirming!

Thanks for your gentle answer!

It turned out that it was my mistake to only implement the object mapper on the encoder of webclient. I managed to add this configuration and works fine for me!

                clientDefaultCodecsConfigurer.defaultCodecs().jackson2JsonDecoder(Jackson2JsonDecoder(objectMapper(), MediaType.APPLICATION_JSON))

I’ll close this issue Have a good day!
