javai是JAXB的新手。如何将两个具有不同名称空间的不同xml合并为一个具有根元素的xml并将其解组？
我需要合并由两个不同SOAP调用生成的两个XML。这两个XML中都有不同的名称空间。我使用wsimport工具从两个单独的wsdl生成与JAXB兼容的类。每个生成的包中的一个类都有一个“Response”对象，该对象有一个从XML中检索根节点/元素的API。当我为下面的代码解组每个xml时，我的代码是有效的，但当我将其与另一个具有不同名称空间和不同根节点的xml组合时，由于某种原因，它将不起作用。我试图创建一个@XmlRootElement类CdmData{…}它包含用于在解组后从合并的XML填充数据的getter，但是，它不起作用。 有人能帮我吗这里的代码出了什么问题
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();
}
我已经将以下xml合并为一个名为LoanContractMerge的xml。xml。。。。问题是，我无法解组合并的xml。我试图使用@xmlementroot和@xmlementwrapper，但它们似乎对我的代码不起作用。详情如下：

***Java Class:***
@XmlRootElement(name = "cdmData")

public class CdmData {

**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.
