我是JAXB的新手。如何将具有不同命名空间的两个不同的xmls合并到一个带有根元素的xml中并解组它？

标签： java jaxb unmarshalling

我需要合并两个不同SOAP调用生成的两个xmls。这两个XML都有不同的命名空间。我使用wsimport工具生成两个sepearte WSDL的JAXB兼容类。每个生成的包中的一个类具有“Response”对象，该对象具有用于从XML检索根节点/元素的API。当我解组每个单独的xml时，我的代码可以工作。下面的代码工作，但当我将它与另一个具有不同命名空间和不同根节点的xml结合使用时，由于某种原因它将无法工作。我试图创建一个@XmlRootElement类CdmData {...}，其中包含getters以在解组后填充合并XML中的数据，但是，它不起作用。 任何人都可以帮助我解决我的代码错误吗？

try {
    JAXBContext jaxbContext = JAXBContext.newInstance(ContractRetrievalResponse.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    contractAppData = ((JAXBElement<ContractRetrievalResponse>) jaxbUnmarshaller.unmarshal(new StreamSource(xmlFile1), ContractRetrievalResponse.class)).getValue();
} catch (JAXBException e) {
    Logger.error(ContractAppCdmData.class, "Error! System cannot unmarshal an xml file.");
    e.printStackTrace();
}

我已将xmls合并到一个名为LoanContractMerge.xml的xml中....问题是，我无法解组合并的xml。我也尝试使用@XmlElmentRoot和@XmlElementWrapper，但它们似乎不适用于我的代码。以下是详细信息：

**XML 1:**

****XML 2:****
<?xml version="1.0" encoding="UTF-8"?>
<p1:ContractRetrievalResponse xmlns:p="http://www.somelocation.com/cdm"
    xmlns:p1="com/somelocation/contractapp/service">

***Java Class:***
@XmlRootElement(name = "cdmData")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "CdmData", propOrder = {
    "loanPurchaseContractStructure", "singleFamilyLoanFullViews",
    "errors"
})

public class CdmData {
    @XmlElement(name = "SingleFamilyLoanFullViews")
    protected SingleFamilyLoanFullViews singleFamilyLoanFullViews;
    @XmlElement(name = "Errors")
    protected ErrorList errors;
    @XmlElement(name = "LoanPurchaseContractStructure", nillable = true)
    protected List<LoanPurchaseContractStructure> loanPurchaseContractStructure;

    public SingleFamilyLoanFullViews getSingleFamilyLoanFullViews() {
        return singleFamilyLoanFullViews;
    }

    public void setSingleFamilyLoanFullViews(SingleFamilyLoanFullViews value) {
        this.singleFamilyLoanFullViews = value;
    }
    public List<LoanPurchaseContractStructure> getLoanPurchaseContractStructure() {
        if (loanPurchaseContractStructure == null) {
            loanPurchaseContractStructure = new ArrayList<LoanPurchaseContractStructure>();
        }
        return this.loanPurchaseContractStructure;
    }
}

**Class with unmarshal method:**

public class CDMDataFactory {
........
........
String xmlFileName = "LoanContractMerge.xml";

FileReader xmlFileReader = null;
URL url = ClassLoader.getSystemResource(xmlFileName);
try {
    xmlFileReader = new FileReader(url.getFile());
} catch (Exception ex) {
    ex.printStackTrace();
}                       }
CdmData cdmData = null;
try {
    JAXBContext jaxbContext = JAXBContext.newInstance(CdmData.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    cdmData = ((JAXBElement<CdmData>) jaxbUnmarshaller
            .unmarshal(new StreamSource(xmlFileReader),
                    CdmData.class)).getValue();
} catch (JAXBException e) {
    Logger.error(CDMDataFactory.class,
            "Error! System cannot unmarshal an xml file.");
    e.printStackTrace();
}
.......
.......
} //CDMFactory.java class 

I am not sure why I am not able to unmarshal the merged xml. When I use only one xml, it works as expected. Below  are the xsd files.
