lift json: пользовательский сериализатор для java 8 LocalDateTime, вызывающий исключение сопоставления

У меня есть класс с именем child2, который я хочу сериализовать и десериализовать, мой класс содержит атрибут LocalDateTime, для которого мне нужно написать собственный сериализатор, который я пробовал с двумя решениями, но оба выдавали исключения, вот мой код

Решение 1

case class Child2(var str:String,var Num:Int,MyList:List[Int],val myDate : LocalDateTime = LocalDateTime.now()){
                        var number:Int=555
                       }
class Message1SerializerDateTime  extends Serializer[LocalDateTime]{
private val LocalDateTimeClass = classOf[LocalDateTime]

  def deserialize(implicit format: Formats): PartialFunction[(TypeInfo, JValue), LocalDateTime] = {
    case (TypeInfo(LocalDateTimeClass, _), json) => json match {
      case JString(dt) =>  LocalDateTime.parse(dt)
      case x => throw new MappingException("Can't convert " + x + " to LocalDateTime")
    }
  }

  def serialize(implicit format: Formats): PartialFunction[Any, JValue] = {
    case x: LocalDateTime => JString(x.toString)
  }
}

  object MessageTest extends App {

 implicit val formats = /*Serialization.formats(NoTypeHints)*/DefaultFormats + new FieldSerializer[Child2]+new Message1SerializerDateTime
        var c= new Child2("Mary", 5,List(1, 2),LocalDateTime.now())

                      c.number=1
                    //  println("number"+c.number)
              val ser = write(c)
                     println("Child class converted to string" +ser) 
                     var obj=read[Child2](ser)
                     println("object of Child is "+obj)
                     println("str"+obj.str)
                     println("Num"+obj.Num)
                     println("MyList"+obj)
                     println("myDate"+obj.myDate)
                     println("number"+obj.number)  

}

и его метание mapping exception

Child class converted to string{"number":1,"str":"Mary","Num":5,"MyList":[1,2],"myDate":"2015-07-28T16:45:44.030"}

    )

    c
  }
  case x => throw new MappingException("Can't convert " + x + " to Interval")
 }
}
  def serialize(implicit format: Formats): PartialFunction[Any, JValue] = {
case x: Child2 => 
  JObject(
    JField("str", JString(x.str)) :: JField("Num", JInt(x.Num)) ::

    JField("myDate", JString(x.myDate.toString)) :: 
    JField("number", JInt(x.number)) :: Nil
  )
}
}

object MessageTest extends App
{
implicit val formats = /*Serialization.formats(NoTypeHints)*/DefaultFormats+new Message1Serializer
        var c= new Child2("Mary", 5,List(1, 2),LocalDateTime.now())

                      c.number=1
                    //  println("number"+c.number)
              val ser = write(c)
                     println("Child class converted to string" +ser) 
                     var obj=read[Child2](ser)
                     println("object of Child is "+obj)
                     println("str"+obj.str)
                     println("Num"+obj.Num)
                     println("MyList"+obj)
                     println("myDate"+obj.myDate)
                     println("number"+obj.number)
}

это также бросает исключение сопоставления

пожалуйста, помогите мне, как я могу решить эту проблему. Как мне написать сериализатор для Java 8 LocalDateTime
