как я могу использовать сессию?Я использую в «@Scheduled».но проблема в 'HttpServletRequest' Как я могу его использовать? 

@Controller
public class SchedulerController {

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

     @Resource private SchedulerYoutubeSearchService schedulerYoutubeSearchService;
     @Autowired(required=true)
     private HttpServletRequest request;

     private static int read = 0;

     @Scheduled(cron = "0/30 * * * * ?")
     protected void testScheduler() {
         UserInfoDto udto = (UserInfoDto) request.getSession().getAttribute("UserInfoDto"); 
         System.out.println(udto);
         try {
             if(udto !=null) {
                schedulerYoutubeSearchService.searchYoutube(udto, read);
                read += 1;
             }
        } catch (Exception e) {
            logger.error("SchedulerController.testScheduler error : ",e);
        } 
     }
   }

Исключение: 

ERROR: org.springframework.scheduling.support.TaskUtils$LoggingErrorHandler - Unexpected error occurred in scheduled task.
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
