How to configure an endpoint in Spring to accept both form data and XML request body?

I have a small question regarding Spring's MVC data binding capabilities. I do have the following controller class:

@Controller
@RequestMapping("/foo")
public class FooController() {

    // … some init stuff //

@RequestMapping(value = "/{id}/edit.{format}", method = RequestMethod.POST)
    public ModelAndView editFoo(@RequestBody FooItem foo, @PathVariable("format") String format) {

        // some code here to edit the FooItem //
    }
}

I want to be able to post form data as well as XML against this method. 开发者_如何学CFor that to work I added two message converters to my applicationContext.xml: The default formHttpMessageConverter and an XStream marshaller.

This works fine, but I have a problem, that if I use @RequestBody and post form data against the URL, the server responds with a 415 Error. If I remove this annotation, form data works well and Spring creates the object for me, but if I post XML against it, I get an empty object.

Is there any way around this or do I need to have 2 methods to be able to handle both of the incoming formats?

Thanks in advance!

I think you need two methods.

FormHttpMessageConverter doesn't have the same databinding capabilities as @ModelAttribute provides, it can't bind request to the specified target class, only to MultiValueMap (see javadoc).
