如何添加XML属性JAXB注释类XmlElementWrapper? [英] How can I add xml attributes to jaxb annotated class XmlElementWrapper?
问题描述
我有一个XmlElementWrapper注解类,如:
I have a class with a XmlElementWrapper annotation like:
...
@XmlElementWrapper(name="myList")
@XmlElements({
@XmlElement(name="myElement") }
)
private List<SomeType> someList = new LinkedList();
...
这code产生XML像
... This code produces XML like
<myList>
<myElement> </myElement>
<myElement> </myElement>
<myElement> </myElement>
</myList>
到目前为止好。
但现在我需要的属性添加到列表标记获取XML像
But now I need to add attributes to the list tag to get XML like
<myList number="2">
<myElement> </myElement>
<myElement> </myElement>
<myElement> </myElement>
</myList>
有没有一种聪明的方式实现这一目标而无需创建一个包含重新presents列表中的一个新的类?
Is there a 'smart way to achieve this without creating a new class that contains represents the list?
推荐答案
我得到了你的问题更好的解决方案。
I got a better solution for your question.
有关让XML的Java对象,请使用以下code:
For making Xml Java object, use the following code:
import java.util.*;
import javax.xml.bind.annotation.*;
@XmlRootElement(name="myList")
public class Root {
private String number;
private List<String> someList;
@XmlAttribute(name="number")
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
@XmlElement(name="myElement")
public List<String> getSomeList() {
return someList;
}
public void setSomeList(List<String> someList) {
this.someList = someList;
}
public Root(String numValue,List<String> someListValue) {
this();
this.number = numValue;
this.someList = someListValue;
}
/**
*
*/
public Root() {
// TODO Auto-generated constructor stub
}
}
要使用JAXB运行上面的code,使用以下命令:
To run the above code using JAXB, use the following:
import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
List<String> arg = new ArrayList<String>();
arg.add("FOO");
arg.add("BAR");
Root root = new Root("123", arg);
JAXBContext jc = JAXBContext.newInstance(Root.class);
Marshaller marshaller = jc.createMarshaller();
marshaller.marshal(root, System.out);
}
}
这将产生下面的XML作为输出:
This will produce the following XML as the output:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<myList number="123">
<myElement>FOO</myElement>
<myElement>BAR</myElement>
</myList>
我觉得这是比较有帮助你。
