我尝试了两种方法：将对象作为对象发布或包装到 JAXBElement 中。没有什么对我有用。

//Create Object
Estate DTO estateOne = new EstateDTO("Hotel", "StreetOne", 1, 111111, "England", 1);

    ///setting up xstream
    XStream xstream = new XStream();
    xstream.processAnnotations(EstateResourceIF.class);
    xstream.processAnnotations(EstateDTO.class);
    xstream.autodetectAnnotations(true);

    xstream.setClassLoader(new EstateDTO().getClass().getClassLoader());
    xstream.alias("estateDTO", EstateDTO.class);
    xstream.alias("estateId", Integer.class);
            xstream.alias("estateName", String.class);

    //post object
    service.post(estateOne).write(System.out);

我什至尝试将它包装在 JAXB 中：

 JAXBElement<EstateDTO> estate = new JAXBElement<EstateDTO>(new QName("estate"), EstateDTO.class, estateOne);

同样的问题：我得到：

即使我尝试使用：

EstateResourceIF EstateResource = service.wrap(EstateResourceIF.class);

    List<Preference<MediaType>> acceptedMediaTypes = new ArrayList<Preference<MediaType>>();
    acceptedMediaTypes.add(new Preference(MediaType.APPLICATION_JSON));
    service.getClientInfo().setAcceptedMediaTypes(acceptedMediaTypes);

    estateResource.postEstate(estateOne);

解决方案的更多事实：

    @XmlRootElement
    //JAX-RS supports an automatic mapping from JAXB annotated class to XML and JSON
    @XmlAccessorType(XmlAccessType.FIELD)
    public class EstateDTO implements Serializable{

服务器端帖子

        @POST
        @Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
        public Response postEstate(EstateDTO c) {
            //EstateDTO c = estate.getValue();
            System.out.println(c);
            String generatedId = generateID();

            c.setOwner(sec.getUserPrincipal().getName());
            return postAndGetResponse(c);
        }

cosole上的系统说

 EstateDTO [estateId=null, owner=null, estateName=null, street=null, number=0, extraAddressLine=null, zip=0, country=null, space=0, tenants=[]]

postAndGetResponse 方法：

        private Response postAndGetResponse(EstateDTO estate) {
            Response res;
            System.out.println(estate);
            if(EstateDAO.instance.getEstateDao().containsKey(estate.getEstateId())) {
                res = Response.serverError().status(409).build();
            } else {
                res = Response.created(UriBuilder.fromUri(uriInfo.getAbsolutePath() + "/" + estate.getEstateId()).build()).entity(estate).build();
                EstateDAO.instance.getEstateDao().put(estate.getEstateId(), estate);
            }
            return res;
        }

您的 JAXB 映射似乎是正确的，并且由于您已经映射了您的类，因此@XmlRootElement您不需要将对象包装在JAXBElement. 我还仔细检查了您的 XStream 映射似乎与您的 JAXB 映射匹配（见下文）。我目前的猜测是问题出在你的 post 方法上。您能否将服务中的 post 方法添加到您的问题中？

房地产DTO

我EstateDTO通过利用 JAXB 作为异常配置来简化您的课程。这意味着您只需要在行为与默认映射不同的地方添加注释。

演示

下面是一些独立的 JAXB 代码，以确保一切正常。

package forum11410653;

import java.io.*;
import javax.xml.bind.*;
import com.thoughtworks.xstream.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        EstateDTO estateDTO = new EstateDTO("Hotel", "StreetOne", 1, 111111,
                "England", 1);

        // setting up xstream
        XStream xstream = new XStream();
        xstream.processAnnotations(EstateDTO.class);
        xstream.autodetectAnnotations(true);

        xstream.setClassLoader(new EstateDTO().getClass().getClassLoader());
        xstream.alias("estateDTO", EstateDTO.class);
        xstream.alias("estateId", Integer.class);
        xstream.alias("estateName", String.class);
        StringWriter writer = new StringWriter();
        xstream.toXML(estateDTO, writer);

        String xml = writer.toString();
        System.out.println(xml);

        // setting up JAXB
        JAXBContext jc = JAXBContext.newInstance(EstateDTO.class);
        Unmarshaller unmarshaller = jc.createUnmarshaller();
        EstateDTO unmarshalled = (EstateDTO) unmarshaller
                .unmarshal(new StringReader(xml));

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(unmarshalled, System.out);
    }

}
