Java:jaxb-generics

如何让jaxb绑定到我的向量？我似乎无法让它绑定包含泛型的向量，因为它抱怨无法识别我的类“shape”或其任何子类型。。“[javax.xml.bind.JAXBException:class shape.shape或其任何超类在此上下文中都不为人所知。”

您应该在

JAXBContext

JAXBContext context = JAXBContext.newInstance(XVector.class, shape.class);

（注意：按照惯例，

Shape

应该大写）

谢谢你，我为没有大写我的班级感到羞耻。我还发现这个链接很有用，因为它清理了我的xml：

javax.xml.bind.MarshalException

[javax.xml.bind.JAXBException: class shape.Rectangle nor any of its super class is known to this context.]

public void saveFile(File filename) {
    try {
        FileOutputStream fout = new FileOutputStream(filename);
        objs.setVector(objVec);
        JAXBContext context = JAXBContext.newInstance(XVector.class);
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        marshaller.marshal(objs, fout);
        fout.close();
    } catch (JAXBException e) {
       e.printStackTrace ();
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(this, ex.toString(), "Error", JOptionPane.ERROR_MESSAGE);
    }
}

JAXBContext context = JAXBContext.newInstance(XVector.class, shape.class);
