我可以阻止在Action阶段调用ModelAttribute方法吗？

Question

我有以下课程

@Controller
@RequestMapping( "VIEW" )
@SessionAttributes( "application" )
public class EditApplicationController {

    private static final Logger logger = LoggerFactory.getLogger( EditApplicationController.class );

    private final ApplicationService applicationService;

    @Autowired
    public EditApplicationController( ApplicationService appServ ) {
        this.applicationService = appServ;
    }

    @RenderMapping( params = "action=editApplicationForm" )
    public String showEditApplication() {
        return "editApplicationForm";
    }

    @ActionMapping( params = "action=editApplication" )
    public void editApplication( @Valid ApplicationDTO application ) {
        try {
            this.applicationService.updateCmmiApplication( application );
        } catch ( final ApplicationNotFound e ) {
            logger.error( "No application exists with the given application id." );
        }
    }

    @ModelAttribute( "application" )
    public Application getApplication( @RequestParam long appId ) throws ApplicationNotFoundException {
        final Application app = this.applicationService.findApplicationById( appId );

        if ( app == null ) {
            throw new ApplicationNotFoundException();
        }

        return app;
    }
}

问题是当我处于Action阶段时，我不想要或需要检索ModelAttribute，因为我完全处理提交的表单对象。我可以使请求参数不是必需的并执行空检查，或者我可以添加一个新的控制器仅用于执行操作，但这些都感觉很笨拙。
