jaxb不要元帅属性

Question

我有一些由Jaxb Mave插件生成的类：

@XmlType
@XmlRootElement(name = "Foo", namespace = "urn://some-urn")
public class Foo {
    @XmlAttribute(name = "id", required = true)
    protected String id;
    @XmlAttribute(name = "name", required = true)
    protected BigInteger name;
    @XmlAttribute(name = "age", required = true)
    protected String age;

我需要从该类中元使用对象，但是JAXB将属性作为一个元素。

必要：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:Foo xmlns:ns2="urn://some-urn" id="1" name="Boris" age="43">
    //some elements in the root element
</ns2:Foo>

提供：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:Foo xmlns:ns2="urn://some-urn">
    <id>1</id>
    <name>Boris</name>
    <age>43</age>
</ns2:Foo>

编组方法：

public String marshalToXml(Foo foo) {
        StringWriter stringWriter = new StringWriter();
        try {
            Marshaller marshaller = JAXBContext.newInstance(Foo.class).createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
            QName qName = new QName("urn://some-urn",
                    "Foo");
            JAXBElement<Foo> bar = new JAXBElement<>(qName, Foo.class, foo);
            marshaller.marshal(bar, stringWriter);
            return stringWriter.toString();
        } catch (JAXBException e) {
            log.error(e.getMessage(), e);
        }
        return null;
    }
