How to write custom property deserializers in jackson

Multi tool use
Multi tool use












1














I have a lot of different classes that have a property that needs custom deserialization.



Example:



data class Specific(val a: String, val b: String) // <-- Needs special deserialization
data class Foo(val value: String, val sp: Specific)
data class Bar(val something: Int, val sp: Specific)


I have tried creating a custom deserializer using the StdDeserializer. And this only works if I write the deserializer for the actual class (Foo and Bar), but I only want to write one for the Specific type.



As I'm using Kotlin I would love the non java Annotated way to to it.
