gson 有没有办法让 Boot 的反序列化器在测试中反序列化一个对象？

我在Sping Boot 中有以下对象：

data class PolygonDto(
    var polygon: org.locationtech.jts.geom.Geometry? = null
)

和以下请求Map：

@RequestMapping(method = [RequestMethod.POST])
fun postPolygon(@RequestBody polygonDto: PolygonDto): PolygonDto {
    return save(polygonDto)
}

当我用json发送一个请求时如下：

{"areaDataId":1,"polygon":{"type":"Polygon","coordinates":[[[100,0],[101,0],[101,1],[100,1],[100,0]]]}}

它可以很好地反序列化对象。但如果我尝试使用以下代码反序列化对象以进行测试：

val gsonBuilder = GsonBuilder().registerTypeAdapter(PolygonDto::class.java, Gson())
    val polygonDto: PolygonDto = gsonBuilder.create().fromJson(
        "{\"areaDataId\":1,\"polygon\":{\"type\":\"Polygon\",\"coordinates\":[[[100,0],[101,0],[101,1],[100,1],[100,0]]]}}",
        PolygonDto::class.java
    )

我得到一个异常：

我假设问题出在我的反序列化器中，“Gson（）”不起作用，我必须编写一个自定义的反序列化器。有没有办法让Sping Boot 的反序列化器以与在@RestController中反序列化相同的方式反序列化对象？
UPD：
我尝试了以下几种方法：

val polygonDto = ObjectMapper().readValue(json, PolygonDto::class.java)

并得到了一个例外：

是的。在我的例子中，我需要使用PolygonDto p = new ObjectMapper().readValue(json, PolygonDto.class)，正如Anthony Raymond的注解中所述。如果你已经用GSON或其他jsonMap器替换了ObjectMapper，你可以使用它。
