java – 使用带有名称空间和模式的Jaxb进行XML解组

<?xml version="1.0" encoding="UTF-8"?>
<xs:msgdata xmlns:xs="http://www.myCompany.com" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.myCompany.com msgdata.xsd">
  <xs:msgid>MsgID001</xs:msgid>
  <xs:msgHash>hlkJKLHljkhkjlHKJLHkjl6y987HJKH</xs:msgHash> 
</xs:msgdata>

还向我发送了一个模式文档(称为msgdata.xsd).我正在使用JAXB将上述xml文档解组为Java对象.
解组代码如下所示：

final JAXBContext context = JAXBContext.newInstance(clazz);
SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = sf.newSchema(new File("C:tempmsgdata.xsd"));

final Unmarshaller unmarshaller = context.createUnmarshaller();
unmarshaller.setSchema(schema);

return (T) unmarshaller.unmarshal(new StringReader(xml));

XML的目标对象如下所示(然后将对象转换为休眠实体.

@XmlRootElement(name = "msgdata")
public class Message {

    private     String  msgid;
    private     String  msgHash;

    @XmlElement(name = "msgid")
    public String getMsgid() {
        return msgid;
    }

    public void setMsgid(String msgid) {
        this.msgid = msgid;
    }

    @XmlElement(name = "msgHash")
    public String getMsgHash() {
        return msgHash;
    }
    public void setMsgHash(String msgHash) {
        this.msgHash = msgHash;
    }

几个问题：

>我有一个休息服务,我将收到上面显示格式的XML文档.架构文档的参考是什么.我知道架构文档用于验证XML文档.我认为它的工作方式是我使用该模式来验证我通过REST服务收到的XML文档.现在的问题是我如何访问架构？我只是将它存储在我的文件系统上并访问它,如上所示？

XML文档具有对模式的引用(请参阅schemaLocation条目).它如何在我的文件系统上找到架构文档？ XML文档中是否需要该模式引用？

>现在的XML文档无法解组.当我尝试解组时,我收到以下错误：

我认为命名空间是在xml文档中定义的.我要么没有正确使用架构,要么命名空间定义不正确.我究竟做错了什么？

谢谢.
