deserializing json4s with generic type - json

Question

Update: Looked closer into the rest of my code and I had an issue elsewhere which is why it was not working. Thanks
I wanted to know if one can use json4 serializer to deserialize and object that uses generic.
My json data has similar traits with different information for one part
For example, I have Superhero and who has skills different
*Json Data
{
"type": "Blue",
"name": "Aquaman",
"age": "4",
"skills": {
"Cooking": 9,
"Swimming": 4
}
}
{
"type": "Red",
"name": "Flash",
"age": "8",
"skills": {
"Speed": 9,
"Punctual": 10
}
}
So what I wanted to do was
case class Superhero[T](
`type`: String,
name: String,
age: Int,
skills: T
)
and the respective skill case class
case class BlueSkill(
Cooking: Int,
Swimming: Int
)
case class RedSkill(
Speed: Int,
Punctual: Int
)
but when I read and try to map it to another object I get null in my dataframe.
val bluePerson = read[Superhero[BlueSkill]](jsonBody)
So wanted to know if reading generic object is possible with json4.

Answer 1

Sure it can be done, why would it work any differently from non-generic types?
import org.json4s.native.{Serialization => S}
import org.json4s.DefaultFormats
implicit val fmts = DefaultFormats
S.read[Superhero[RedSkill]]("""|{
| "type": "Red",
| "name": "Flash",
| "age": 8,
| "skills": {
| "Speed": 9,
| "Punctual": 10
| }
|}""".stripMargin)
But frankly, I'd stay away from json4s or any other introspection nonsense and use a typeclass-based library such as circe instead.
