Как десериализовать `xs: date` и` xs: dateTime` в `XMLGregorianCalendar`, используя Джексона?

Question

Я десериализирую xml в pojos:

final JaxbAnnotationModule module = new JaxbAnnotationModule();
final PolymorphicTypeValidator ptv = BasicPolymorphicTypeValidator.builder()
        .allowIfBaseType(XMLGregorianCalendar.class)
        .build();

mapper = new XmlMapper();
mapper.registerModule(module);
mapper.activateDefaultTyping(ptv, ObjectMapper.DefaultTyping.NON_CONCRETE_AND_ARRAYS);
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

• Поскольку XMLGregorianCalendar является абстрактным типом, я добавил PolymorphicTypeValidator.
• Поскольку у меня нет аннотаций Джексона но jaxb аннотации я использую JaxbAnnotationModule.

Когда я сейчас пытаюсь десериализовать действительный xml в мое pojo, я получаю следующую ошибку:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Unexpected token (VALUE_STRING), expected START_ARRAY: need JSON Array to contain As.WRAPPER_ARRAY type information for class javax.xml.datatype.XMLGregorianCalendar

Я пытался использовать пользовательские десериализаторы, но это не помогло. Есть ли что-то особенное, что мне нужно сделать для XMLGregorianCalendar? У меня есть другие абстрактные типы, которые работают нормально, используя PolymorphicTypeValidator

EDIT

Ниже приведен POJO, сгенерированный JAXB XJ C:

Мой тест:

@Test
public void canSerializeToXMLAndDeserializeToPOJO() throws DatatypeConfigurationException, JsonProcessingException {
    final PartialDate partialDate = new PartialDate();
    partialDate.setDate(XMLGregorianCalendar_Test.create());
    partialDate.setTime(XMLGregorianCalendar_Test.create());

    final String serialized = mapper.writeValueAsString(partialDate);

    System.out.println(serialized);

    final PartialDate deserialized = mapper.readValue(serialized, PartialDate.class);

    assertThat(partialDate).isEqualTo(deserialized);
}

Сериализованный XML:

<PartialDate>
  <date>java.util.GregorianCalendar</date>
  <date>1585296330000</date>
  <time>java.util.GregorianCalendar</time>
  <time>1585296330000</time>
</PartialDate>

И при десериализации я получаю сообщение об ошибке выше.

Использование Пользовательский сериализатор, так что XML выглядит так:

<PartialDate>
  <date>javax.xml.datatype.XMLGregorianCalendar</date>
  <date>1585296330000</date>
  <time>javax.xml.datatype.XMLGregorianCalendar</time>
  <time>1585296330000</time>
</PartialDate>

выдает ту же ошибку.
