Question

我期望通过使用xml-path来跳过需要忽略的元素，但它似乎并没有这样做。我错过了什么吗？

它应该忽略嵌套元素“responseHeader”

错误：

Caused by: org.xml.sax.SAXParseException: unexpected element (uri:"", local:"responseHeader"). Expected elements are <{}response>
    at org.eclipse.persistence.internal.oxm.record.UnmarshalRecordImpl.startUnmappedElement(UnmarshalRecordImpl.java:957)
    at org.eclipse.persistence.internal.oxm.record.UnmarshalRecordImpl.startElement(UnmarshalRecordImpl.java:814)

    at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2756)

这是xml输入

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="/admin/tabular.xsl"?>
<response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

绑定文件：

<?xml version="1.0"?>
<xml-bindings 
        xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
        version="2.1" package-name="com.dao">
    <java-types>
        <java-type name="DaoResult">
            <xml-root-element name="response"/>
            <xml-type prop-order="results"/>
            <java-attributes>
                <xml-element java-attribute="results" xml-path="responseBody/record" type="com.aol.pxy.movies.model.WeekBox" container-type="java.util.List"/>
                <xml-transient java-attribute="totalCount"/>
                <xml-transient java-attribute="cachedTime"/>
                <xml-transient java-attribute="firstResult"/>
                <xml-transient java-attribute="inputQuery"/>
                <xml-transient java-attribute="paginationHandle"/>
            </java-attributes>
        </java-type>
    </java-types>
</xml-bindings>

模特课：

public class DaoResult<T>  extends AbstractModel implements Serializable {

    private static final long serialVersionUID = -6369563906973225250L;

    @XmlTransient
    private String inputQuery;

    @Deprecated
    private Integer count = -1;

    private Integer totalCount;

    private List<T> results;

    private String paginationHandle;

    private Date cachedTime = new Date();

注意：我是EclipseLink JAXB (MOXy)主管，是JAXB (JSR-222)专家组的成员。

当我意外地将输入文档指向外部映射文档时，我收到了类似的错误。当我做了下面的小样本时，everthing按预期工作。

演示代码

在下面的示例代码中，oxm.xml是外部映射文档，input.xml是输入数据文档。

import java.io.File;
import java.util.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextProperties;

public class Demo {

    public static void main(String[] args) throws Exception {
        Map<String, Object> properties = new HashMap<String, Object>(1);
        properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, "src/com/dao/oxm.xml");
        JAXBContext jc = JAXBContext.newInstance(new Class[] {DaoResult.class}, properties);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/com/dao/input.xml");
        DaoResult result = (DaoResult) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(result, System.out);
    }

}
