我是新来JAXB，并与从XML到Java类的实例转换的烦恼。

我有以下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>

我开发Java代码：

和

这些示例代码运行，但数据是错误的：

请帮我。

此外，我不明白的情况下，我将有很多不同

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

我能做什么容易和简单？
我的意思是这种情况： 

<resData>
<data name="crDate">2004-12-17</data>
<data name="exDate">2009-01-02</data>
<data name="password">7fe11fd9d97ee40bdf57e561427c0a6</data>
<data name="dns">dns1.onlinenic.net</data>
<data name="dns">dns2.onlinenic.net</data>
<data name="r_name">123456</data>
<data name="r_org">123456</data>
<data name="r_country">BJ</data>
<data name="r_province">mokcup</data>
<data name="r_city">123456</data>
<data name="r_street">123456</data>
<data name="r_postalcode">123456</data>
<data name="r_voice">+86.5925391800</data>
<data name="r_fax">+86.5925391800</data>
<data name="r_email">asdfasdf@sadf.com</data>
....

Answer 1:

谢谢布莱斯Doughan。 但挖了超过10主题后我决定我不得不开始用相反的方式。

我创造了新的测试，编组我的数据（对象）。 其实，我用TDD（测试驱动开发）的方式，我认为。 所以，我充满了我的对象与测试数据和应用编组站（从数据创建的XML），并看到了我。 数据是不正确的。 我看着其他主题还（感谢名单这一个的Java / JAXB：和解组XML到基于属性的具体子类 ）并纠正我的数据结构

记得我还想得到

<?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>

现在我的数据是： 

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 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;
    }
}

和： 

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

import java.util.List;

import javax.xml.bind.annotation.XmlRootElement;

/**
 * @author annik
 * 
 */
@XmlRootElement
public class ResData
{
    private List<XmlData> data;

    /**
     * Getter.
     * 
     * @return the data
     */
    public List<XmlData> getData() {
        return data;
    }

    /**
     * Setter.
     * 
     * @param data
     *            the data to set
     */
    public void setData(List<XmlData> data) {
        this.data = data;
    }
}

    @XmlElement

        try {

        } catch (Exception e) {
            // TODO Auto-generated catch block

    /**

    public void setCode(Integer code) {

    @XmlElement
    public void setResData(ResData resData) {
        this.resData = resData;
    }

    @Override
    public String toString() {
        return "category=" + category + ", action=" + action + ", code=" + code + ", msg=" + message
                + ", resData:" + resData.toString();
    }
}

和VU-alja：我得到的！

正如你可以看到下面它的工作原理，以另一种方式： http://i.stack.imgur.com/35nzb.png
