This is what I have:

**SomeController.java**

```
@Controller
@RequestMapping(value = "/foo", produces = MediaType.APPLICATION_JSON_VALUE)
public class SomeController {
    @RequestMapping(value = "/bar", method = RequestMethod.POST)
    public @ResponseBody ResponseEntity<Resource<Baz>> createCampaign(@RequestBody Foobar foobar) {
        ...
    }
}

```

Now, I need to use a custom `JsonDeserialiser` for `foobar`, but only for this particular endpoint, every other endpoint with has `Foobar` as its `@RequestBody` should use the default. How can this be achieved?
