xml Java：如何忽略标记前缀

Question

将以下xml作为post参数，如何忽略“v1:”或“typ:”名称空间，以便将每个标记映射到Java类？ 我想从这类xml创建一个对象，但由于标记之前的名称空间，我遇到了一个错误（没有它们可以正常工作，但我无法更改xml）

Java控制器方法是：

@RequestMapping(value = "/XML", method = RequestMethod.POST, produces = {MediaType.APPLICATION_ATOM_XML_VALUE})
    public ResponseEntity<GetCompanyStructureDetailsResponseContent> getXml(@RequestBody GetCompanyStructureDetailsRequest request){
  // how should I filter this XML....
return null;
    }

请求时的XML是：

<v1:getCompanyStructureDetailsRequest>
  <v1:trackingInformation>
        <typ:eventLocalID>234233423434234234</typ:eventLocalID>
        <typ:applicationID>MSD</typ:applicationID>
        <typ:originApplicationID>MSD</typ:originApplicationID> 
  </v1:trackingInformation>
  <v1:getCompanyStructureDetailsRequestContent>
    <v1:customer>
      <v1:organizationIdentifier>
        <v1:companyIndex>33503</v1:companyIndex>
      </v1:organizationIdentifier>
    </v1:customer>
  </v1:getCompanyStructureDetailsRequestContent>
</v1:getCompanyStructureDetailsRequest>

错误为：

w.s.m.s.DefaultHandlerExceptionResolver : Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not unmarshal to [class com.example.dto.request.GetCompanyStructureDetailsRequest]: null; nested exception is javax.xml.bind.UnmarshalException
 - with linked exception:
[org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 39; The prefix "v1" for element "v1:getCompanyStructureDetailsRequest" is not bound.]

SimpleXml可以做到这一点，首先是一些POJO：

@XmlName("v1:getCompanyStructureDetailsRequest")
public class GetCompanyStructureDetailsRequest {
    @XmlName("v1:trackingInformation")
    public TrackingInformation tracking;
    @XmlName("v1:getCompanyStructureDetailsRequestContent")
    public CompanyStructure structure;
}
public class TrackingInformation {
    @XmlName("typ:eventLocalID")
    public String eventLocalID;
    @XmlName("typ:applicationID")
    public String applicationID;
    @XmlName("typ:originApplicationID")
    public String originApplicationID;
}
public class CompanyStructure {
    @XmlName("v1:customer")
    public Customer customer;
}
public class Customer {
    @XmlWrapperTag("v1:organizationIdentifier")
    @XmlName("v1:companyIndex")
    public Integer companyId;
}

然后序列化并打印：

public static void main(final String... args) throws IOException {
    final SimpleXml simple = new SimpleXml();
    final GetCompanyStructureDetailsRequest r = simple.fromXml(xml, GetCompanyStructureDetailsRequest.class);
    System.out.println(r.structure.customer.companyId);
}

此代码将打印：

33503

SimpleXml位于maven central：
