两个不同的 POJO 编组到一个 XML

Question

I need send SOAP request like this

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" 
xmlns:ser="foo.com/Public/Services" 
xmlns:typ="foo.com/Public/Types">
   <soap:Header/>
   <soap:Body>
      <ser:InputParms>
         <!--some parameters:-->
      </ser:InputParms>
      <ser:Metadata>
         <!--some parameters:-->
      </ser:Metadata>
   </soap:Body>
</soap:Envelope>

How can see XML contains two objects: InputParms and Metadata.

jaxb plugin generates two corresponding POJO from WSDL. I try to send SOAP request using spring ws. It is possible to use following method

public Object marshalSendAndReceive(String uri,
                                        final Object requestPayload,
                                        final WebServiceMessageCallback requestCallback)

The method accepts only one object as payload. But I need send two objects. I cannot understand how do it? Or how can I marshal these two POJO to on XML?

I've found a solution. I compose two different SOAP message and merge two envelopes to single.

public class ClientImpl extends WebServiceGatewaySupport {

private static final String ACTION = "foo.com/services";

@Value("${uri}")
private String uri;

public Response sendRequest(ManualRequest request) {
    WebServiceTemplate template = getWebServiceTemplate();

    Response response = (Response) template.marshalSendAndReceive(
            uri,
            request.getSecondPayloadObject(),
            new SoapPayloadMergeCallback(request.getFirstPayloadObject(),
                    ACTION,
                    getMarshaller())
    );

    return response;
}

private static final class SoapPayloadMergeCallback implements WebServiceMessageCallback {

    public SoapPayloadMergeCallback(Object additionalPayloadObject, String soapAction, Marshaller marshaller) {
        this.additionalPayloadObject = additionalPayloadObject;
        this.soapAction = soapAction;
        this.marshaller = marshaller;
    }

    private final Object additionalPayloadObject;
    private final String soapAction;
    private final Marshaller marshaller;

    @Override
    public void doWithMessage(WebServiceMessage message) throws IOException {
        SoapMessage soapMessage = (SoapMessage) message;
        soapMessage.setSoapAction(soapAction);

        Node additional = soapMessage.getDocument().cloneNode(true);

        MarshallingUtils.marshal(marshaller, additionalPayloadObject, message);
        soapMessage = (SoapMessage) message;
        Document target = soapMessage.getDocument();

        merge(target, (Document) additional);
    }

    private void merge(Document target, Document additional) {
        Element envelopeElementAdditional = additional.getDocumentElement();
        Node bodyNodeAdditional = envelopeElementAdditional.getChildNodes().item(1);
        Node elementToMove = bodyNodeAdditional.getFirstChild();

        Node importedNode = target.adoptNode(elementToMove);

        Element envelopeElementTarget = target.getDocumentElement();
        Node bodyNodeTarget = envelopeElementTarget.getChildNodes().item(1);
        bodyNodeTarget.appendChild(importedNode);
    }
}

}
