UnmarshalException：意外元素（uri：“ http://www.namespace.com/RTS”，本地：“ container”）

Question

我正在尝试将xml映射到java类。Xml来自第三方服务。结构相同，但是前缀或名称空间可能不同。 XML：

<?xml version="1.0" encoding="UTF-8"?>
<xdms:container xmlns:xdms="http://www.namespace.com/RTS" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xdms:uid="FHGHDFGDFJKGDFHG" xdms:version="3.2">
    <xdms:requisites>
        <xdms:documentKind>letter</xdms:documentKind>
        <xdms:classification>main</xdms:classification>
        <xdms:annotation>unknown</xdms:annotation>
    </xdms:requisites>
</>

我的班级：

@XmlRootElement(name = "container")
@XmlAccessorType(XmlAccessType.FIELD)
public class Container {
    private static final long serialVersionUID = 1L;

    @XmlElement(name = "requisites")
    private Requisites requisites;

    public Container() {
        super();
    }

    @Override
    public String toString() {
        return "Container{" +
                "requisites=" + requisites +
                '}';
    }
}

@XmlRootElement(name = "requisites")
@XmlAccessorType(XmlAccessType.FIELD)
public class Requisites implements Serializable {
    private static final long serialVersionUID = 1L;

    private String documentKind;
    private String classification;
    private String annotation;

    public Requisites() {
        super();
    }

    @Override
    public String toString() {
        return "Requisites{" +
                "documentKind='" + documentKind + '\'' +
                ", classfication='" + classification + '\'' +
                ", annotation='" + annotation + '\'' +
                '}';
    }
}

以及运行解析的主类：

    JAXBContext jaxbContext;
    File xmlFile = new File("test.xml");
    try
    {
        jaxbContext = JAXBContext.newInstance(Container.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        Container cont = (Container) jaxbUnmarshaller.unmarshal(xmlFile);

        System.out.println(cont);
    }
    catch (JAXBException e)
    {
        e.printStackTrace();
    }

我收到错误：

javax.xml.bind.UnmarshalException：意外元素（uri：“ http://www.namespace.com/RTS”，本地：“容器”）。预期元素位于com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext.handleEvent（UnmarshallingContext.java:726）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.Loader.reportError（Loader.java:247）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.Loader.reportError（Loader.java:242）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.Loader.reportUnexpectedChildElement（Loader.java:109）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext $ DefaultRootLoader.childElement（UnmarshallingContext.java:1131）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext._startElement（UnmarshallingContext.java:556）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext.startElement（UnmarshallingContext.java:538）在com.sun.xml.internal.bind.v2.runtime.unmarshaller.SAXConnector.startElement（SAXConnector.java:153）在com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement（AbstractSAXParser.java:509）在com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement（XMLNSDocumentScannerImpl.java:374）在com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl $ NSContentDriver.scanRootElementHook（XMLNSDocumentScannerImpl.java:613）在com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl $ FragmentContentDriver.next（XMLDocumentFragmentScannerImpl.java:3132）在com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl $ PrologDriver.next（XMLDocumentScannerImpl.java:852）

Answer 1

类似的东西：

@XmlRootElement(name = "container", namespace = "http://www.namespace.com/RTS")
@XmlAccessorType(XmlAccessType.FIELD)
public class Container {

    @XmlElement(name = "requisites", namespace="http://www.namespace.com/RTS")
    private Requisites requisites;

}

您可能还需要向Requisites中的每个元素添加名称空间。

Answer 2

@XmlRootElement(name="container", namespace="http://www.namespace.com/RTS")

如果仍然抛出相同的错误，则还必须在@XmlElement中指定名称空间属性：

@XmlElement(name="requisites", namespace="http://www.namespace.com/RTS")

您的Requisites标记内的每个属性还应在其@XmlElement批注中包含名称空间。
