Marshaller in spring integration

Question

I am trying to marshal java objects to xml in spring integration. i've tried to use new MarshallingTransformer. but i don't know how to pass the marshaller into it. This is my code:

return IntegrationFlows.from(Http.inboundGateway("/foo")
                            .requestMapping(m -> m.methods(HttpMethod.POST)
                                   
                            )
                    )
                
                    .transform(xmlToObjectTransformer)
                    .convert(Customer.class)
                    .transform(new MarshallingTransformer("the marshaller should come here"))

                    .get();

The question is not clear. You probably need to learn what are those marshallers and how to configure them: https://docs.spring.io/spring-framework/docs/current/reference/html/data-access.html#oxm.

Then you just need to have a bean for respective Marshaller and inject it into that MarshallingTransformer ctor.
