我创建了java类 @XmlRootElement和@XmlElement但它给出了命名空间错误请帮我把这个字符串转换成java对象

我的代码java代码

File file = new File("Test.xml");
    JAXBContext jaxbContext = JAXBContext.newInstance(OadrPayload.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    OadrPayload stationSearch = (OadrPayload) jaxbUnmarshaller.unmarshal(file);

XML到对象的Java代码 -

public class ReadXmlFileCode {
    public static void main(String[] args) {

     try {
         //create object from xml
        File file = new File("C:\\Qstn.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(Quiz.class);

        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        Quiz customer = (Quiz) jaxbUnmarshaller.unmarshal(file);
        for(Question qs:customer.getQuestion())
        {
            System.out.println(qs.getQuestionText());
            System.out.println(qs.getAnswer().get(0).getCorrect());
        }
        ////create xml from object
        File file1 = new File("C:\\file1.xml");
        JAXBContext jaxbContext1 = JAXBContext.newInstance(Quiz.class);
        Marshaller jaxbMarshaller = jaxbContext1.createMarshaller();

        // output pretty printed
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        jaxbMarshaller.marshal(customer, file1);
        jaxbMarshaller.marshal(customer, System.out);

      } catch (JAXBException e) {
        e.printStackTrace();
      }

    }
}

现在创建一个Quij.java，Question.java和Answer.java thrre文件并且工作已经完成。
