Spring WS endpoint add multiple child elements to soap body - soap

Question

I'm creating a soap webservice with Spring WS. I need to add multiple child elements to my soap body. At the moment I only get this working with an additional wrapper element.
Example of a response I should return:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope>
<soap:Body>
<Response>
<ResponseResult href="#id1"/>
</Response>
<Result id="id1">
...
</Result>
</soap:Body>
</soap:Envelope>
But I only get this working:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope>
<soap:Body>
<Wrapper>
<Response>
<ResponseResult href="#id1"/>
</Response>
<Result id="id1">
...
</Result>
</Wrapper>
</soap:Body>
</soap:Envelope>
Has somebody an idea how to solve this? Do you need additional information?

Answer 1

I finally solved it. I basically did the same as in this post: https://stackoverflow.com/a/15741795/6931969 but I'll provide some more informations.
I extended the EndpointInterceptorAdapter and changed the method handleResponse(MessageContext messageContext, Object endpoint).
import org.springframework.stereotype.Component;
import org.springframework.ws.context.MessageContext;
import org.springframework.ws.server.endpoint.interceptor.EndpointInterceptorAdapter;
import org.springframework.ws.soap.saaj.SaajSoapMessage;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPMessage;
import java.util.LinkedList;
import java.util.List;
#Component
public class CustomEndpointInterceptorAdapter extends EndpointInterceptorAdapter {
/**
* Removes wrapper element.
*/
#Override
public boolean handleResponse(MessageContext messageContext, Object endpoint) throws Exception {
System.out.println("--------------------- Interceptor ---------------------");
SOAPMessage soapMsg = ((SaajSoapMessage)messageContext.getResponse()).getSaajMessage();
SOAPBody soapBody = soapMsg.getSOAPBody();
// Get all child nodes of wrapper
Node wrapper = soapBody.getFirstChild();
List<Node> children = getChildren(wrapper);
soapBody.removeContents();
// Add children to SOAPBody
children.forEach(node -> addNode(soapBody, node));
soapMsg.saveChanges();
return true;
}
private List<Node> getChildren(Node wrapper) {
List<Node> result = new LinkedList<>();
NodeList children = wrapper.getChildNodes();
for(int i = 0; i < children.getLength(); i++) {
result.add(children.item(i));
}
return result;
}
private void addNode(SOAPBody soapBody, Node node) {
try {
soapBody.addChildElement((SOAPElement)node);
} catch (SOAPException e) {
System.out.println("Doesn't work for Node: " + node.getNodeName());
e.printStackTrace();
}
}
}
