JAXB/MOXY中嵌套项解封的空值

Question

如有任何线索将不胜感激。谢谢，约翰

JAXBContext jc = JAXBContext.newInstance(Xmeml.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
Xmeml xmeml = (Xmeml) unmarshaller.unmarshal(inFile);


@XmlRootElement(name = "sequence")
public class Sequence {

    @XmlElement(required = true)
    protected String name;
    @XmlElement(required = true)
    protected BigInteger duration;
    @XmlElement(required = true)
    protected Rate rate;
    @XmlElement(required = true)
    protected Timecode timecode;
    @XmlElement(required = true)
    protected BigInteger in;
    @XmlElement(required = true)
    protected BigInteger out;
    @XmlElement(required = true)
    protected Media media;



@XmlRootElement(name = "clipitem")
public class Clipitem {

    @XmlElement(required = true)
    protected String name;
    @XmlElement(required = true)
    protected BigInteger duration;
    @XmlElement(required = true)
    protected Rate rate;
    protected boolean enabled;
    @XmlElement(required = true)
    protected BigInteger in;
    @XmlElement(required = true)
    protected BigInteger out;
    @XmlElement(required = true)
    protected BigInteger start;
    @XmlElement(required = true)
    protected BigInteger end;
    @XmlElement(required = true)
    protected String masterclipid;
    protected boolean ismasterclip;
    @XmlElement(required = true)
    protected Labels labels;
    @XmlElement(required = true)
    protected Comments comments;
    @XmlElement(required = true)
    protected Sequence sequence;

XML是巨大的，但这里有一个片段，序列中的媒体是空的，而它不应该是空的。

您的dom对象与XML不匹配。例如，序列的第一个元素是uuid，而bean的最后一个元素是uuid，“updateBehavior”将完全丢失。其他豆子也有类似的问题。附加的xml文档根本无法根据jaxb模型进行验证，这可能是无法正确读取它的原因。

从模型中获取架构：

JAXBContext con = JAXBContext.newInstance(Xmeml.class);
File dir = new File("D:\\Temp\\schema");
con.generateSchema(new MySchemaOutputResolver(dir));

class MySchemaOutputResolver extends SchemaOutputResolver {

    protected File baseDir;

    public MySchemaOutputResolver(File dir)
    {
        super();
        baseDir =  dir;
    }

    @Override
    public Result createOutput( String namespaceUri, String suggestedFileName ) throws IOException {
        return new StreamResult(new File(baseDir,suggestedFileName));
    }
}

在反编组时根据架构进行验证：

JAXBContext con = JAXBContext.newInstance(Xmeml.class);
SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = sf.newSchema(new File("D:\\Temp\\schema\\schema1.xsd"));
Unmarshaller umar = con.createUnmarshaller();
umar.setSchema(schema);
Xmeml mem = (Xmeml)umar.unmarshal(new File("D:\\Temp\\testcase\\Surround Test.xml"));
