JAXB unmarshalling without XmlRootElement annotation?

Question

Is there any way we can un-marshall for a class without @XmlRootElement annotation? Or are we obligated to enter the annotation?

for example:

public          


        

Answer 1

I use the generic solution as follows:

public static  String objectToXmlStringNoRoot(T obj, Class objClass, final String localPart) throws JAXBException {

    JAXBContext jaxbContext = JAXBContext.newInstance(objClass);
    Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

    // To format XML
    jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);

    //If we DO NOT have JAXB annotated class
    JAXBElement jaxbElement = new JAXBElement<>(new QName("", localPart), objClass, obj);

    StringWriter sw = new StringWriter();
    jaxbMarshaller.marshal(jaxbElement, sw);

    return sw.toString();
}
