JAXB endless data structure, recursive binding?

问题:

sBefore starting a project I wanted to get a short heads up here.

If I have a structure like this:

<root>
<a>
    <a>
        <a>
            <a>
                <a/>
            </a>
        </a>
    </a>
    <a>
    </a>
</a>

The a element can hold a elements and this endlessly deep.

Do I just write a class A and then give it a List as a member? JAXB does the magic automatically then? Or is this structure not possible?

回答1:

Yes you can have the following:

@XmlAccessorType(XmlAccessType.FIELD)
public class A {

    private List<A> a;

}

And your JAXB (JSR-222) implementation will marshal it correctly.
