Trigger 404 in Spring-MVC controller?

Question

How do I get a Spring 3.0 controller to trigger a 404?

I have a controller with @RequestMapping(value = "/**", method = RequestMethod.GET) and for some URLs accessing the controller, I want the container to come up with a 404.

Since Spring 3.0 you also can throw an Exception declared with @ResponseStatus annotation:

@ResponseStatus(value = HttpStatus.NOT_FOUND)

public class ResourceNotFoundException extends RuntimeException {

    ...

}

@Controller

public class SomeController {

    @RequestMapping.....

    public void handleCall() {

        if (isFound()) {

            // whatever

        }

        else {

            throw new ResourceNotFoundException(); 

        }

    }

}
