Spring MVC 5 Rest API convert XML to Bean using JAXB - spring

Question

We are migrating Jersey Endpoints to Spring MVC Rest endpoints. These endpoints consumes and produces XML. But Spring MVC is unable to convert the XML input bean because XML tag and Bean's property name is different. I have to take request as String and Convert it using JAXB explicitly. Is there any better way to do that?
