带有地图对象的 Kotlin 地图序列化和反序列化错误类

问题描述

我正在尝试创建序列化和反序列化对象。我正在这样做：

   var mapper = ObjectMapper()

   var stringTest =   mapper.writeValueAsstring(stringContainsObjectFilter);
    
   val raw: Any = mapper.readValue(stringTest,Any::class.java)
   val filtersFromString = mapper.convertValue(raw,ObjectFilter::class.java)

   val objectFilters = ObjectFilter()
   quoteFilters.rosterLine= filtersFromString.rosterLine
   quoteFilters.outOfPocketMax = filtersFromString.outOfPocketMax
   quoteFilters.cost = filtersFromString.cost

这是我要序列化和反序列化的类

open  class ObjectFilter{

    var rosterLine: Map<RosterEnum,List<Int>>? = null

    var outOfPocketMax: Map<String?,List<Int>>? = null

    var monthlyCost: List<MonthlyCost>? = null

}

但我收到以下消息：

"Response[ObjectFilters]; Could not unconvert attribute"

有人可以帮我吗？我一直在尝试解决它而没有结果:(

解决方法

我找到了解决方案，这就是我所做的并且有效：

val rawResult = mapper.convertValue(mapper.readValue(string,Any::class.java),Any::class.java)
        val filtersFromString = rawResult  as? ObjectFilter ?: ObjectFilter()
