I've used data classes with Jackson-kotlin module. I think that's the key. Ensure kotlinmodule is registered with Jackson and it gets 'smarter'

do you have a link to something on github that shows this? I feel like that would be cool to look at

try a quick :google: for

jackson kotlin

Not easily at hand. This is work project, so closed.

it also use Kotlin-Reflect Library too.

keep this in mind if this is in the android context ☝️ pretty much makes jackson-kotlin unviable

very true. I'm writing jvm server so less of a concern.

Moshi uses code generation instead of reflection and is being developed as a replacement for gson.
