spray json example

SprayJsonTest.scala

package com.pagero.services.emailapi

import spray.json._
import akka.http.scaladsl.marshallers.sprayjson.SprayJsonSupport
import spray.json.DefaultJsonProtocol

case class Customer (id :Option[Int],name: Option[String])

object Test extends App with DefaultJsonProtocol with SprayJsonSupport{
  implicit val CompanyFormat = jsonFormat2(Customer)
  val cust = Customer(Some(1),Some("Cool"))
  val json = cust.toJson.prettyPrint
  println(json)
}

result.
{ "id": 1, "name": "Cool" }

When an attribute of the Customer model is None, The spray json serializer will skip that attribute.
ie. Customer(Some(1),None)
{ "id": 1 }
