Question

我正在尝试使用JAXB封送来保存JList。这是我的编组方法：

public void save() {
    try {

        File save = new File("save.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(Window.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

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

        jaxbMarshaller.marshal(listB, save);
        jaxbMarshaller.marshal(listB, System.out);

          } catch (JAXBException e) {
        e.printStackTrace();
          }
    System.out.println(listB);  
}

我打印出listB以确保它有效。我仍然收到以下错误消息：

您只能编组或解组已检测/注释的类。我没有检查JList，但我不相信它来自为JAXB注释的sdk。有关如何使用JAXB https://jaxb.java.net/
