JAXB @XmlAttribute @XmlValue prawdziwy przykład

Question

Jestem nowy w JAXB i mam problemy z konwersją z XML do instancji klasy Java.

Mam następujące XML:

<?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> 

i rozwijać następujący kod Java:

/**

Te przykłady kodu uciekać, ale dane są błędne:

Proszę mi pomóc.

Również nie rozumiem w przypadku będę mieć wiele różnych

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

Co mogę zrobić łatwo i prosto?
mam na myśli tę sprawę:

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

Answer 1

dziękuję Blaise Doughan. Ale po wykopaniu ponad 10 tematów zdecydowałem, że MUSZĘ zacząć od przeciwnej strony.

Utworzyłem nowy test, który MARSHALLING moje dane (obiekty). Właściwie korzystałem z TDD (test Driven Development). Tak więc wypełniłem moje obiekty danymi testowymi i zastosowałem program Marshalling (utworzono XML z danych) i zobaczyłem, że mam. Dane były niepoprawne. Spojrzałem do innego tematu również (dzięki tej jednej Java/JAXB: Unmarshall Xml to specific subclass based on an attribute) i poprawić mój Struktura danych

pamiętać Id jak dostać

<?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> 

Teraz moje dane są:

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.XmlValue; 

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; 
    } 
}

    public List<XmlData> getData() { 
     return data; 
    }
