如何将XML对象转换为JAXB java obejct？

我的XML

---

这里有一个例子——你可以遵循-

quick.xml

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

现在创建Quij.java、Question.java和Answer.java thrre文件

工作已经完成。

也提供课程。

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

        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();
      }

    }
