JAXB @XmlAttribute @XmlValue 真实例子 [英] JAXB @XmlAttribute @XmlValue real example
本文介绍了JAXB @XmlAttribute @XmlValue 真实例子的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是 JAXB 新手，在将 XML 转换为 Java 类实例时遇到了麻烦.
I'm new to JAXB and have troubles with conversion from XML to a Java class instance.
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>
我开发了以下 Java 代码:
and I develop the following Java code:

这些代码示例运行但数据错误:
These code examples run but data is wrong :

请帮助我.
我也不明白，万一我会有很多不同的
Also I do not understand in case I will have many different
<data ...>..</data>
我可以轻松简单地做些什么?
我的意思是这种情况:
What could I do easy and simply?
I mean this case:
<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_voice">+86.5925391800</data>

<data name="r_email">asdfasdf@sadf.com</data>

推荐答案
谢谢 Blaise Doughan.但在挖掘了超过 10 个主题后，我决定我必须从相反的方式开始.
Thank you Blaise Doughan. But after dug more over 10 topics I decide I HAD TO to start with opposite way.
我创建了新的测试来编组我的数据(对象).实际上，我认为我使用了 TDD(测试驱动开发)方式.因此，我用测试数据填充我的对象并应用编组(从 DATA 创建 XML)并看到我得到了.数据不正确.我还查看了其他主题(谢谢这个 Java/JAXB:根据属性将 Xml 解组为特定子类)并更正我的数据结构
I created new test which MARSHALLING my data (objects). Actually, I used TDD (test Driven Development) way I think. So, I filled up my Objects with test data and applied Marshalling (created XML from DATA) and saw that I got. Data Was Incorrect. I looked to other topic also (thanx this one Java/JAXB: Unmarshall Xml to specific subclass based on an attribute ) and correct my data Structure
记得我想得到
<?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;
}
/**

*

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

public void setCategoryEnum(OnicEnumCategory category) {

}
@XmlElement

} catch (Exception e) {

public void setActionEnum(OnicEnumAction action) {
this.action = action;
}
@XmlElement
public void setAction(String action) {
try {

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
LOG.error(e.getMessage());
}
}
/**

@XmlElement

return code;
}
/**

*/
public void setCode(Integer code) {
this.code = code;
}
/**

*
* @return the message
*/
@XmlElements(value={@XmlElement})
public String getMessage() {
return message;
}
/**
* Setter.
*
* @param message
* the message to set
*/
public void setMessage(String message) {
this.message = message;
}
/** Getter.
* @return the resData
*/
public ResData getResData() {
return resData;
}
/** Setter.
* @param resData the resData to set
*/
@XmlElement
public void setResData(ResData resData) {

}
@Override
public String toString() {
return "category=" + category + ", action=" + action + ", code=" + code + ", msg=" + message
+ ", resData:" + resData.toString();
}
}
和似曾相识:我明白了！
and vu-alja : I got that !
正如您在下面看到的，它以另一种方式工作:http://i.stack.imgur.com/35nzb.png
And as you can see below it works to another way : http://i.stack.imgur.com/35nzb.png
