Exemple réel JAXB @XmlAttribute @XmlValue

Question

Je suis nouveau sur JAXB et j'ai des problèmes avec la conversion de XML en une instance de classe Java.

J'ai le XML suivant:

<?xml version="1.0"?>
<response>
    <category>client</category>
    <action>Greeting</action>
    <code>1000</code>
    <msg>Your Connection with API Server is Successful</msg>
    <resData>
        <data name="svDate">2009-02-16 06:22:21</data>
    </resData>
</response>

et je développe le code Java Java:

Ces exemples de code s'exécutent mais les données sont incorrectes:

Aidez-moi, s'il vous plaît.

De plus, je ne comprends pas au cas où j'aurais beaucoup de différents

<data ...>..</data> 

Que pourrais-je faire facilement et simplement?
Je veux dire ce cas:

<resData>
<data name="crDate">2004-12-17</data>
<data name="exDate">2009-01-02</data>
<data name="password">7fe11fd9d97ee40bdf57e561427c0a6</data>

Answer 1

Merci Blaise Doughan. Mais après avoir creusé plus de 10 sujets, je décide que je devais commencer par la voie opposée.

J'ai créé un nouveau test qui MARSHALLING mes données (objets). En fait, j'ai utilisé TDD (test Driven Development) comme je pense. Donc, j'ai rempli mes objets avec des données de test et appliqué le Marshalling (créé du XML à partir de DATA) et j'ai vu que j'avais obtenu. Les données étaient incorrectes. J'ai aussi regardé un autre sujet (merci celui-ci Java/JAXB: Unmarshall Xml vers une sous-classe spécifique basée sur un attribut ) et corrige ma structure de données

rappelez-vous que j'aimerais obtenir

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<response>
    <code>1000</code>
    <message>Big message</message>
    <resData>
        <data name="svDate">2013.03.14</data>
    </resData>
</response>

Maintenant mes données sont:

package net.regmaster.onlinenic.model.response.resdata;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

import org.Eclipse.persistence.oxm.annotations.XmlCustomizer;

/**
 * @author annik
 *
 */
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name="data")
//@XmlCustomizer(ResDataCustomiser.class)
public class XmlData
{
    @XmlAttribute(name="name")
    private String name;

    @XmlValue
    private String value;

    /** Getter.
     * @return the name
     */
    public String getName() {
        return name;
    }

    /** Setter.
     * @param name the name to set
     */
    public void setName(String name) {
        this.name = name;
    }

    /** Getter.
     * @return the value
     */
    public String getValue() {
        return value;
    }

    /** Setter.
     * @param value the value to set
     */
    public void setValue(String value) {
        this.value = value;
    }
}

    }
