How to ignore a key from json while mapping in case class

Question

If i have a JSON

{"name":"jack","email":"jackt@gmail.com"}

now while mapping this JSON i want only name to be mapped in my case class, for example

case class Person(name:String)

How can we achieve this?

Answer 1

import spray.json._


case class Person(name: String)
object PersonFormat extends DefaultJsonProtocol {
  implicit val personFormat = jsonFormat1(Person)
}
import PersonFormat._

val source = """{ "name":"jack", "email":"jackt@gmail.com" }"""
source.parseJson.convertTo[Person]

You need to define the JsonProtocol with a implicit val.
