java - 使用 JAXB 解码字符串 XML 不起作用并仅返回空值

Question

我试图将字符串 XML 解码为 POJO 对象，但没有成功。这是我正在使用的代码

MyObject myobject = JAXB.unmarshal(new StringReader(myxmlstring), MyObject.class);

Xml 的结构和对象的结构如下:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:SomePerson xmlns:ns2="http://to/something">
    <SomePerson>
        <person>
            <name>joe</name>
        </person>
    </SomePerson>
</ns2:SomePerson>

这是我的对象:

@XmlRootElement(name="SomePerson")
@XmlAccessorType(XmlAccessType.FIELD)
public class MyObject {

    @XmlElement(name = "name")
    private String name;

    //getter and setters
}

建议你做这样的事情::

        final DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
        final InputSource is = new InputSource();
        is.setCharacterStream(new StringReader("<root><node1></node1></root>")); // put your xml string here

        final Document doc = db.parse(is);

        final XMLInputFactory xif = XMLInputFactory.newFactory();
        final DOMSource domSource = new DOMSource(document);
        final XMLStreamReader xsr = xif.createXMLStreamReader(domSource);
        final XMLReaderWithoutNamespace xr = new XMLReaderWithoutNamespace(xsr);
        final Unmarshaller unmarshaller = JAXBContext
                .newInstance("POJO LOCATION").createUnmarshaller();
        return (POJOClass) unmarshaller.unmarshal(xr);

请告诉我这是否有帮助
