推荐答案

自 Spring 3.0 起，您还可以抛出用 @ResponseStatus 注释:

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();
        }
    }
}
