JAXB - 调用在另一个类中解组该方法

Question

伙计，这个问题可能是一个愚蠢的问题，但如果确实如此，请原谅我。 下面是我希望解组的XML结构。我已经设置了同样的代码和工作正常。但是我希望在另一个类中调用unmarshall方法，以便通过调用getter方法获取值。

XML结构：

<dataroot>
    <CustomerData>
        <DOCDELIVERY>
            <LocationType>xyz</LocationType>
            <DocumentName>docuName</DocumentName>
            <OutputFilePath>some path</OutputFilePath>
            <OutputFileName>file name</OutputFileName>
        </DOCDELIVERY>
        <LABEL>
            <ItemNumber>007</ItemNumber>
            <VendorHeader1>vendor header1</VendorHeader1>
            <data1></data1>
            <data2></data2>
        </LABEL>
    </CustomerData>
</dataroot>

下面是我正在执行XML解组的类：

public class ReadXml {

    public void readXml(String inputXml)
            throws ParserConfigurationException, SAXException, IOException,
            JAXBException {

        File inputXmlFile = new File(inputXml);
        JAXBContext jaxbContext = JAXBContext.newInstance(Dataroot.class);
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        Dataroot dataRoot = (Dataroot) unmarshaller.unmarshal(inputXmlFile);
        CustomerData customerData = dataRoot.getCustomerData();
        DocDelivery docDelivery = customerData.getDOCDELIVERY();
        Label label = customerData.getLABEL();
        System.out.println(label.getVendorHeader1());
        //return label;
        //System.out.println(label.getVendorHeader1());
    }

}

以下是XML结构的POJO类：

CustomerData.java

@XmlAccessorType(XmlAccessType.FIELD)
public class CustomerData {

    @XmlElement(name = "DOCDELIVERY")
    private DocDelivery DOCDELIVERY;

    @XmlElement(name = "LABEL")
    private Label LABEL;

    public CustomerData() {
    };

    public DocDelivery getDOCDELIVERY() {
        return DOCDELIVERY;
    }

    public void setDOCDELIVERY(DocDelivery docDelivery) {
        DOCDELIVERY = docDelivery;
    }

    public Label getLABEL() {
        return LABEL;
    }

    public void setLABEL(Label label) {
        this.LABEL = label;
    }
}

Dataroot.java

@XmlRootElement(name = "dataroot")
@XmlAccessorType(XmlAccessType.FIELD)
public class Dataroot {

    @XmlElement(name = "CustomerData")
    private CustomerData CustomerData;

    public Dataroot() {
    };

    public CustomerData getCustomerData() {
        return CustomerData;
    }

    public void setCustomerData(CustomerData customerData) {
        this.CustomerData = customerData;
    }
}

Label.java

@XmlAccessorType(XmlAccessType.FIELD)
public class Label {

    @XmlElement(name = "VendorHeader1")
    private String VendorHeader1;

    public Label() {
    };

    public String getVendorHeader1() {
        return VendorHeader1;
    }

    public void setVendorHeader1(String VendorHeader1) {
        this.VendorHeader1 = VendorHeader1;
    }
}

我想在另一个类的ReadXML类中调用readXML方法，我想访问下面类中的Label标记值。 具体来说，我想在下面的类＆amp;中的inputXML方法中调用readXML方法。访问Label类的getter / setter方法。 如何实现这一目标？

FXMLController.java

public class FXMLController {
    @FXML
    private Button inputXmlFileBtn;
    @FXML
    private TextField inputXmlName;

    public void inputXmlFileChooser() throws ParserConfigurationException, SAXException, IOException, JAXBException {
        FileChooser fileChooser = new FileChooser();
        // Set extension filter
        fileChooser.getExtensionFilters().addAll(
                new ExtensionFilter("XML files (*.xml)", "*.xml"));

        // Open Dialog
        File file = fileChooser.showOpenDialog(null);

        // Set the path for inputXmlName text field
        if (file != null) {
            inputXmlName.setText(file.getPath());
        }
    }
}
