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);
我甚至尝试将其包装在JAXB中：
JAXBElement<EstateDTO> estate = new JAXBElement<EstateDTO>(new QName("estate"), EstateDTO.class, estateOne);
同样的问题： 我明白了：

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：
EstateDTO课程：
@XmlRootElement
//JAX-RS supports an automatic mapping from JAXB annotated class to XML and JSON
@XmlAccessorType(XmlAccessType.FIELD)
public class EstateDTO implements Serializable{
/**
*
*/
private static final long serialVersionUID = -8545841080597549468L;
@XmlElement(name="estateId")
private String estateId;
@XmlElement(name="owner")
private String owner;
@XmlElement(name="estateName")
private String estateName;
@XmlElement(name="street")
private String street;
@XmlElement(name="number")
private int number;
@XmlElement(name="extraAddressLine")
private String extraAddressLine;
@XmlElement(name="zip")
private int zip;
@XmlElement(name="country")
private String country;
private int space;
private List<String> tenants = new ArrayList<String>();
public EstateDTO() {
}
public EstateDTO(String estateName, String street, int number, int zip, String country, int space) {
this.estateName = estateName;
this.street = street;
this.number = number;
this.zip = zip;
this.country = country;
this.space = space;
}
编辑：
服务器双面发布
@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.setEstateId(generatedId);
c.setOwner(sec.getUserPrincipal().getName());
return postAndGetResponse(c);
}
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;
}

答案 0 :(得分：1)
您的JAXB映射似乎是正确的，并且由于您已使用@XmlRootElement映射了类，因此无需将对象包装在JAXBElement中。我也进行了双重检查，你的XStream映射看起来与你的JAXB映射相匹配（见下文）。我目前的猜测是问题在于你的post方法。您可以将服务中的post方法添加到您的问题中吗？
EstateDTO
我通过利用JAXB异常配置简化了您的EstateDTO类。这意味着您只需要添加注释，其中行为与默认映射不同。
package forum11410653;
import java.io.Serializable;

import javax.xml.bind.annotation.*;
@XmlRootElement
//JAX-RS supports an automatic mapping from JAXB annotated class to XML and JSON

<强>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 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);
}
}
