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();
}
}
}
Starting from Spring 5.0, you don't necessarily need to create additional exceptions:
throw new ResponseStatusException(NOT_FOUND, "Unable to find resource");
Also, you can cover multiple scenarios with one, built-in exception and you have more control.
See more:
Rewrite your method signature so that it accepts HttpServletResponse as a parameter, so that you can call setStatus(int) on it.
Because it's always good to have at least ten ways of doing the same thing:
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class Something {
@RequestMapping("/path")
public ModelAndView somethingPath() {
return new ModelAndView("/", HttpStatus.NOT_FOUND);
}
}
