Spring WS - return non-MTOM on MTOM request - spring

Question

I have a SOAP service that receives a binary attachment (MTOM). The issue is that I would like to return a non-MTOM response (a "clean" SOAP return). The current code return a multipart response and uses "xop+xml" content-type.
The code is:
#Configuration
public class MyWebServiceConfig {
#Value("${config1}")
private String contextPath;
#Value("${config2}")
private String namespace;
#Value("${config3}")
private String wsdl;
#Bean
ServletRegistrationBean<?> webServicesRegistration(ApplicationContext ctx) {
MessageDispatcherServlet messageDispatcherServlet = new MessageDispatcherServlet();
messageDispatcherServlet.setApplicationContext(ctx);
messageDispatcherServlet.setTransformWsdlLocations(true);
return new ServletRegistrationBean<>(messageDispatcherServlet, contextPath, "*.wsdl");
}
#Bean
public Jaxb2Marshaller marshaller() {
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setContextPath(namespace);
marshaller.setMtomEnabled(true);
return marshaller;
}
#Bean
public MarshallingPayloadMethodProcessor methodProcessor(Jaxb2Marshaller marshaller) {
return new MarshallingPayloadMethodProcessor(marshaller);
}
#Bean
DefaultMethodEndpointAdapter endpointAdapter(MarshallingPayloadMethodProcessor methodProcessor) {
DefaultMethodEndpointAdapter adapter = new DefaultMethodEndpointAdapter();
adapter.setMethodArgumentResolvers(Collections.singletonList(methodProcessor));
adapter.setMethodReturnValueHandlers(Collections.singletonList(methodProcessor));
return adapter;
}
#Bean
public SimpleWsdl11Definition contentStore() {
SimpleWsdl11Definition definition = new SimpleWsdl11Definition();
definition.setWsdl(new ClassPathResource(wsdl));
return definition;
}
}
I have tried changing to setMtomEnabled(false) - but then the request is not handled correctly.
Is the anyway of receiving MTOM - but returning a non-MTOM response?
Edit:
Endpoint looks like this:
#Endpoint
public class MyEndpoint {
private ObjectFactory objectFactory;
public MyEndpoint() {
this.objectFactory = new ObjectFactory();
}
#PayloadRoot(localPart = "SendMyRequest", namespace = "somenamespace")
#ResponsePayload
public JAXBElement<MyReceipt> store(#RequestPayload JAXBElement<MyRequest> storeContentRequest) throws IOException {
MyReceipt receipt = new MyReceipt();
receipt.setf1(123);
receipt.setf2(456);
return this.objectFactory.createMyResponse(receipt);
}
}
