Java+Jackson+XML：将一个java对象属性序列化为同名的XML元素

Question

I have a Java object and I would like to serialize it into XML using Jackson library:

public class Point {
    private Integer x;
    private Integer y;
    //getters/setters
}

and I would like to serialize it into following format:

<point>
    <property name="x" value="1" />
    <property name="y" value="1" />
</point>

instead of what I get using Jacskon:

<point>
    <x>1</x>
    <y>1</y>
</point>

I do not want to change the Point object properties or structure. Is there a way to serialize the Point object into required format using a Jackson annotations or custom serializer? If yes then how do I do that?

I am using Jackson library:

public class Serializer {
    XmlMapper mapper = new XmlMapper();

    public void serialize(File file, Object object) throws IOException {
        mapper.writeValue(file, object);
    }

}

You need to mark those properties as attributes like this:

public class Point {

    @JacksonXmlProperty(isAttribute = true)
    private Integer x;
    @JacksonXmlProperty(isAttribute = true)
    private Integer y;
    //getters/setters
}
