How to check value against enum?

[vishwas-trivedi]

I have a enum(string) in the request body and I want to check value in request body is any value in enum or not.
request body:

{
 "userName" : "testName",
 "type": "GENERAL"
}

Enum

enum class UserType {
    GENERAL, ADMIN, SUPER_ADMIN
}

Is there any way to validate type against UserType enum?

Yes, you can add any constraint you want:

enum class UserType {
    GENERAL, ADMIN, SUPER_ADMIN;

   companion object {
    val validStrings: Set<String> = entries.map { it.name }.toSet()
   }
}

data::type {
  addConstraint("{value} must be on of ${UserType.validStrings}") { it in UserType.validStrings }
}
