缺少具有JAXB和解组的[class java.lang.String]类型的指标字段值[SUPP]的类

Question

我正在尝试使用JAXB将JSON解组为Java对象，但是我收到了这个错误：

    [Exception [EclipseLink-43] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: Missing class for indicator field value [SUPP] of type [class java.lang.String].

类的属性看起来像这样，不起作用的属性是“originalType”：

    private final static long serialVersionUID = 1L;
    protected StatusJson status;
    protected PriceJson priceValue;
    protected PriceJson priceRule;
    @XmlElement(name = "element")
    protected List<ElementJson> elements;
    protected PropertyJson property;
    @XmlElement(name = "travellerRef")
    protected List<TravellerRefJson> travellerReves;
    protected PriceJson nettCosts;
    protected InformationObjectJson informationObject;
    @XmlAttribute
    protected ElementSubTypeDefJson subType;
    @XmlAttribute
    protected String originalType;
    @XmlAttribute
    protected String groupRef;

你们有没有想法解决这个问题？

谢谢！

编辑：这是我试图解组的JSON：

        "mandatoryService": {
