How can I make @XmlAttribute in a special order by using JAXB?

Question

I have XML file which needs 3 attributes in an element. How can make the order of street, zip and city attribute as I wanted?

<address street="Big Street" zip="2012" city="Austin">
</address>

@XmlType(name="Street)
@XmlRootElement(name = "Street")
public class Street {

@XmlAttribute
private String name;

@XmlAttribute
private String type;

    ... set and get method
}

Answer 1

You can use @XmlAccessorOrder(has predefined values) or @XmlType(Only works for properties) to govern the ordering.

Samples

Edit :

For custom ordering JAXB specification doesnt provide anything, but you can do if your JAXB provider provides you some features.

Found this link where it speaks about ordering using EclipseLink JAXB.

Answer 2

Anecdotally, the attributes seem to be in reverse order than they are mentioned in code. In my case, I'm using two variables (name & value) and I had to declare them as:

// The inverse order of name & value seems to make them render in XML in name/value order
@XmlAttribute
protected String value;
@XmlAttribute
protected String name;

When the XML is generated, it results in the following:

<attribute name="nameValue" value="valueValue"/>
