Jackson Xml: How to add namespace only on root?

Question

If i declare the namespace on the root element, like this:

@JacksonXmlRootElement(namespace = "urn:stackify:jacksonxml", localName = "PersonData")
public class Person {
    private String id;
    private String name;
    private String note;
}

It produces:

<PersonData xmlns="urn:stackify:jacksonxml">
    <id xmlns="">12345</id>
    <name xmlns="">Graham</name>
    <note xmlns="">Hello</note>
</PersonData>

But I want the namespace only on the root element. The xmlns attribute should not appear on child elements.

How can i archive this?

There is a workaround which I found more elegant for me.

You may define constant for your namespace like this:

@JacksonXmlRootElement(localName = "PersonData")
public class Person {

    @JacksonXmlProperty(isAttribute = true)
    private final String xmlns = "urn:stackify:jacksonxml";

    private String id;
    private String name;
    private String note;
}
