가 Salat 주석이있는 열거 개체입니다 : 나는 데이터베이스에서 데이터를 가져 오기 위해 실행하면, 다음과 같은 오류가 발생합니다. 내가 놓친 게 있니?

@EnumAs(strategy = EnumStrategy.BY_ID) 
object QuestionTypeEnum extends Enumeration { 

    val MULTI_CHOICE = Value("MULTI_CHOICE") 
    val RADIO_BUTTON = Value("RADIO_BUTTON") 
    val DRAG_AND_DROP = Value("DRAG_AND_DROP") 

} 

Answer 1

---------- CONSTRUCTOR EXPECTS FOR PARAM [3] -------------- 
NAME:   quesType 
TYPE:   scala.Enumeration$Value 
DEFAULT ARG [Missing, but unnecessary because input value was supplied] 
@Ignore  false 
---------- CONSTRUCTOR INPUT ------------------------ 
TYPE: scala.None$[scala.runtime.Nothing$] 
VALUE: 
None 

의 오류 메시지가 열거 값을 기대하지만, 데이터베이스가 Option[Enumeration.Value] 포함되어 있음을 시사한다.
