我正在尝试对具有可选Enum输入和默认值的模式执行自省查询。
下面是示例代码
sealed abstract class Weekday(val order: Int) extends EnumEntry with Ordered[Weekday] {
def compare(that: Weekday) = this.order - that.order
}
object Weekday extends Enum[Weekday] {
val values = findValues
case object Monday extends Weekday(2)
case object Tuesday extends Weekday(3)
case object Wednesday extends Weekday(4)
case object Thursday extends Weekday(5)
case object Friday extends Weekday(6)
case object Saturday extends Weekday(7)
case object Sunday extends Weekday(1)
}
case class WeekDayContainer(weekDay: Weekday)
object WeekDayContainer{
val default = WeekDayContainer(Weekday.Monday)
}
//Input Object
case class Context(id: Int, name: String, weekDayContainer: WeekDayContainer = WeekDayContainer.default)
//Macro derivation
implicit val WeekdayInputType: EnumType[Weekday] = deriveEnumType[Weekday](
EnumTypeName("Weekday")
)
implicit val WeekContInputType: InputObjectType[WeekDayContainer] = deriveInputObjectType[WeekDayContainer]()
implicit val pcInputType: InputObjectType[Context] = deriveInputObjectType[Context]()
val contextArg = Argument("Context", pcInputType, description = "context of the xyz")
下面是堆栈跟踪
Invalid default value of field 'weekDayContainer' in input type 'Context'. Field 'Context.weekDayContainer.weekDay' has wrong value: Enum value expected.

添加解码器后，效果很好
private val stringEncoder = implicitly[Encoder[String]]
private val stringDecoder = implicitly[Decoder[String]]
implicit val ChargeTypeEncoder: Encoder[Weekday] = new Encoder[Weekday] {
override def apply(enum: Weekday): Json = stringEncoder.apply(enum.entryName)
}
implicit val ChargeTypeDecoder: Decoder[Weekday] = new Decoder[Weekday] {
final def apply(c: HCursor): Result[Weekday] = stringDecoder.apply(c).flatMap { s =>
val maybeMember = Weekday.withNameOption(s)
maybeMember match {
case Some(member) => Right(member)
case _ =>
Left(DecodingFailure(s"$s' is not a member of enum $Weekday", c.history))
}
}
}
