如何让 Moxy/JAXB 解组以接受 XML 文档中的前缀 [重新定位为让 JAXB 接受根节点元素中缺少的命名空间 xmlns]

问题描述

我正在尝试从 Web 服务解组 XML 文档，但无法设置 JAXB/Moxy 以读取命名空间前缀“ae”。

我可以通过从 XML 文档中手动去除前缀来使其部分工作。我也尝试过使用 package-info.java 方法。

请帮忙指出我哪里出错了？

XML 文档示例

部分 Java 类列表

@XmlRootElement(name="ae:GetItemsByQueryResponse")
@XmlAccessorType(XmlAccessType.FIELD)
public class QueryResponse {
    
    @XmlElement (name="return")
    AuxRecords returnRecords = null;

    public AuxRecords getReturnRecords() {
        return returnRecords;
    }

    public void setReturnRecords(AuxRecords records) {
        this.returnRecords = records;
    }
}

@XmlRootElement(name="return")
@XmlAccessorType(XmlAccessType.FIELD)
public class AuxRecords {

    @XmlElement(name="item")
    private List<AuxRecord> recordsList = null;

    public List<AuxRecord> getRecords() {
        return recordsList;
    }
    
    public void setRecords(List<AuxRecord> inputRecordsList) {
        this.recordsList = inputRecordsList;
    }   
}

@XmlRootElement(name="item")
@XmlAccessorType(XmlAccessType.FIELD)
public class AuxRecord {

    // snow=u_category,sbm=ae:title
    @XmlElement (name="title")
    String name = null;
    
    // sbm=ae:id
    @XmlElement (name="id")
    AuxRecordId id = null;

    @XmlElement(name="extendedField")
    private List<ExtendedField> extensionList = null;
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
    
    public AuxRecordId getId() {
        return id;
    }
    
    public void setId(AuxRecordId inputId) {
        this.id = inputId;
    }

    public List<ExtendedField> getExtensionList() {
        return extensionList;
    }

    public void setExtensionList(List<ExtendedField> extensionList) {
        this.extensionList = extensionList;
    }

    public Object getExtensionSnSysId() {
        // TODO Auto-generated method stub
        return null;
    }
}

@XmlRootElement(name="extendedField")
@XmlAccessorType(XmlAccessType.FIELD)
public class ExtendedField {
    
    @XmlElement (name="id")
    FieldId id;
    
    @XmlElement (name="value")
    FieldValue value;
    
    public FieldId getId() {
        return id;
    }
    public void setId(FieldId id) {
        this.id = id;
    }
    public FieldValue getValue() {
        return value;
    }
    public void setValue(FieldValue value) {
        this.value = value;
    }
}

我在 POJO 类中解组 XML 文档的代码。

public class Test {

    public static void main(String[] args) throws JAXBException{
        
        Map<String,Object> properties = new HashMap<String,Object>();
        properties.put(JAXBContextProperties.OXM_METADATA_SOURCE,"xml-bindings.xml");
        JAXBContext context1 = JAXBContext.newInstance(new Class[] {QueryResponse.class},properties);
        
        Marshaller marshal1 = context1.createMarshaller();
        Unmarshaller umarshal1 = context1.createUnmarshaller();
//      umarshal1.setEventHandler(new javax.xml.bind.helpers.DefaultValidationEventHandler());      
        QueryResponse qresp = (QueryResponse) umarshal1.unmarshal(new File("c:\\temp\\ae_egress.xml"));
        
        marshal1.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,true);
        marshal1.marshal(qresp,System.out);

    }
}

例外

Exception Description: An error occurred unmarshalling the document
Internal Exception: org.xml.sax.SAXParseException; systemId: file:/c:/temp/ae_egress.xml; lineNumber: 1; columnNumber: 35; The prefix "ae" for element "ae:GetItemsByQueryResponse" is not bound.]

更新

将输入源 XML 文档根元素节点更改为

<ae:GetItemsByQueryResponse xmlns:ae="urn:sbmappservices72">
<ae:return>
.....

清除异常。由于它被假定为 SOAP 响应，因此我无法像在测试 ae_egress.xml 中那样修改它。除了在将 DOM 文档或 InputStream 或 XmlInputStream 传递给 unmarshal 之前动态修改它之外，JAXB 或 MOXy 中是否有一些开关或选项也可以解决问题？

这是位于测试包中的 package-info.java 文件。

@XmlSchema (  namespace="urn:sbm,appservices72",elementFormDefault=XmlNsForm.QUALIFIED,xmlns={
@XmlNs(prefix="ae",namespaceURI="urn:sbmappservices72")}
)
package egress;
import javax.xml./bind.annotation.*;
