unexpected element (uri:"", local:"Group"). Expected elements are <{}group>

从xml解组时遇到异常

JAXBContext jc = JAXBContext.newInstance(Group.class); 
Unmarshaller unmarshaller = jc.createUnmarshaller();
Group group = (User)unmarshaller.unmarshal(new File("group.xml"));

组类没有任何注释,group.xml只包含数据.

什么都可能是原因？

尝试使用jaxb将xml响应转换为java对象时,我收到以下错误

       javax.xml.bind.UnmarshalException: unexpected element (uri:"http://SOMETHING/doc/2006-03-01/", local:"Name"). Expected elements are <{}Name>,<{}IsTruncated>,<{}MaxKeys>,<{}Contents>,<{}Prefix>,<{}Marker>

这是我的XML:

       <ListBucketResult xmlns="http://something/doc/2006-03-01/">
           <Name>test2</Name>
            <Prefix/>
            <Marker/>
            <MaxKeys>3</MaxKeys>
            <IsTruncated>false</IsTruncated>
            <Contents>
                  <Key>metadata.xml</Key>
                  <LastModified>2012-09-04T08:29:36.000Z</LastModified>
                    <ETag>6b836fd43c402681506926b2248ec418</ETag>
                    <Size>3258</Size>
                   <StorageClass>STANDARD</StorageClass>
             </Contents>
          </ListBucketResult>

我的java对象类就是这样的

            @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = {
        "name",
        "prefix",
        "marker",
        "maxKeys",
        "isTruncated",
        "contents"
    })
    @XmlRootElement(name = "ListBucketResult")
    public class ListBucketResult {

@XmlElement(name = "Name", required = true)
protected String name;
@XmlElement(name = "Prefix", required = true)
protected String prefix;
@XmlElement(name = "Marker", required = true)
protected String marker;
@XmlElement(name = "MaxKeys")
protected int …

我正试图从Java 8迁移到Java 10,并面临以下问题与JOOQ codegen Maven插件.
