Kotlin 使用Jackson反序列化HTML列表时出现MismatchedInputResponse

我在子化一些包含对象列表的XM时遇到了问题.

为了重现它，我首先将给定对象序列化为HTML，然后try 重新序列化结果，但失败了.

这是我的示例代码:

fun main() {
    val test = CategoriesResponse(listOf(Category(1), Category(2)))
    val xmlMapper = XmlMapper()
    val xml: String = xmlMapper.writeValueAsString(test)
    println(xml)
    val testObject = xmlMapper.readValue(xml, CategoriesResponse::class.java)
    println(testObject)

}


@JacksonXmlRootElement(localName = "response")
data class CategoriesResponse
@JsonCreator
constructor(
    @field:JacksonXmlElementWrapper(localName = "categories")
    @field:JacksonXmlProperty(localName = "category")
    val categoryList: List<Category>
)

data class Category
@JsonCreator
constructor(
    @field:JacksonXmlProperty(isAttribute = true)
    val id: Int,
)

生成的ML刚刚好(格式在此处):

<response>
   <categories>
      <category id="1"/>
      <category id="2"/>
   </categories>
</response> 

我在用 implementation("com.fasterxml.jackson.dataformat:jackson-dataformat-xml")

这是我得到的例外:

Exception in thread "main" com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `java.util.ArrayList<Category>` from Object value (token `JsonToken.FIELD_NAME`)
 at [Source: (StringReader); line: 1, column: 11]
    at com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:59)

如有任何帮助，我们将不胜感激. 谢谢！
