java - Restlet-オブジェクトの投稿（Jaxbを使用している場合でも）が機能しない

Question

私は両方を試しました：オブジェクトをオブジェクトとして投稿するか、JAXBElementにラップします。私には何もうまくいきません。

//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);

JAXBでラップしてみました：

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

同じ問題：私は得る：

私がそれを試してみても：

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);

解決のためのいくつかのより多くの事実：

EstateDTOクラス：

    @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;
        }

編集：

サーバーサイドポスト

        @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);
        }

cosoleのシステムは言う

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

postAndGetResponseメソッド：

        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;
        }

JAXBマッピングは正しいように見えます。クラスをマッピング@XmlRootElementしたので、オブジェクトをでラップする必要はありませんJAXBElement。また、ダブルチェックしたところ、XStreamマッピングがJAXBマッピングと一致しているように見えます（以下を参照）。私の現在の推測では、問題はあなたのpostメソッドにあります。サービスからのpostメソッドを質問に追加できますか？

EstateDTO

EstateDTO例外として構成されているJAXBを利用して、クラスを簡略化しました。これは、動作がデフォルトのマッピングと異なる場合にのみ注釈を追加する必要があることを意味します。

パッケージforum11410653;

import java.io.Serializable;
import java.util.*;
import javax.xml.bind.annotation.*;

@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;

    private String estateId;
    private String owner;
    private String estateName;
    private String street;
    private int number;
    private String extraAddressLine;
    private int zip;
    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;
    }

}

デモ

以下は、すべてが機能することを保証するためのスタンドアロンJAXBコードです。

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);
    }

}

出力

ご覧estateNameのとおり、、、streetおよびcountryが入力されています。

<estateDTO>
  <estateName>Hotel</estateName>
  <street>StreetOne</street>
  <number>1</number>
  <zip>111111</zip>
  <country>England</country>
  <space>1</space>
  <tenants/>
</estateDTO>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<estateDTO>
