Jackson使用整数值反序列化scala枚举

object MyEnum extends Enumeration {
  val Option1 = Value(1)
  val Option2 = Value(2)
  val Option3 = Value(3)
}

import com.fasterxml.jackson.annotation.JsonCreator
import com.fasterxml.jackson.annotation.JsonValue

object MyEnum extends Enumeration {
  val Option1 = Value(1)
  val Option2 = Value(2)
  val Option3 = Value(3)

  @JsonCreator
  def fromInt(value: Int): MyEnum.Value = {
    MyEnum.values.find(_.id == value).getOrElse(throw new IllegalArgumentException(s"Invalid value: $value"))
  }

  @JsonValue
  def toInt(enum: MyEnum.Value): Int = {
    enum.id
  }
}

import com.fasterxml.jackson.databind.ObjectMapper

val json = "{\"myEnum\": 2}"
val objectMapper = new ObjectMapper()
val result = objectMapper.readValue(json, classOf[MyClass])

println(result.myEnum)  // 输出：Option2
