Scala 定义复杂枚举

通常我们需要枚举参数不止两个，Scala提供的枚举类最多定义两个参数：id:Int与name:String。不能满足我们通常要求。

1 object BaseEntryEnum extends Enumeration {
2   type BaseEntryEnum = Value
3   //item_base类别
4   val ITEM_TYPE_PURCHASE_CENTER = Value(31, "采购中心")
5   val ITEM_TYPE_COMPANY = Value(32, "公司")
6   val ITEM_TYPE_OI_ITEM = Value(33, "OI项")
7   val ITEM_TYPE_STORE_ITEM = Value(40, "门店白名单")
8   val ITEM_TYPE_STORE_BLACKLIST = Value(41, "门店黑名单")
9 }

如下enumeratum包可以满足我们需求，可以定义任意参数。

引入如下包

"com.beachape" %% "enumeratum-argonaut" % "1.5.13"

定义复杂枚举：
