How to integrate the Jaxb2Marshaller in the Spring integration route?

Question

1. Created the Jaxb2Marshaller object.
2. Need to convert a java POJO to XML (Marshalling).

Need help in integrating Jaxb2Marshaller in the Integration Route.

Code flow:-

@Bean
    public IntegrationFlow flow() throws JAXBException {
        return from(...).
                .enrichHeaders(...)
                .handle(...)
                .transform(processor()::generateXml)
                .channel(...)
                               .get();
    }

How can I add Jaxb2Marshaller in transform() step?

Answer 1

There is an out-of-the-box transformer to use:

.transform(new MarshallingTransformer(jaxbMarshaller()))

How to create a Jaxb2Marshaller you can consult Spring Framework docs:
