我必须在控制器中设置一个 cookie，但是当我尝试将它添加到 HttpServletResponse 对象时，它似乎不起作用，无论是使用 HttpServletResponse.addCookie(String) 还是使用 CookieGenerator.addCookie(HttpServletResponse, String) [评论]。

@Controller("BookSlotComponentController")
@Scope("tenant")
@RequestMapping(value = ControllerConstants.Actions.Cms.BookSlotComponent)
public class BookSlotComponentController extends AbstractCMSComponentController<BookSlotComponentModel> {
private static Logger LOG = Logger.getLogger(BookSlotComponentController.class);
private final String MORNING_SLOT = "MORNING_SLOT";
private final String AFTERNOON_SLOT = "AFTERNOON_SLOT";
private final String EVENING_SLOT = "EVENING_SLOT";
private final String BOOK_SLOT_SELECTED_DATE = "BOOK_SLOT_SELECTED_DATE";

@Resource(name = "bookSlotFacade")
private BookSlotFacade bookSlotFacade;

@Resource
private TimeService timeService;

@Override
protected void fillModel(final HttpServletRequest request, final Model model, final BookSlotComponentModel component) {
}

@Override
protected void fillModel(final HttpServletRequest request, final HttpServletResponse response, final Model model, final BookSlotComponentModel component) {
    LOG.debug("Start: fillModel");
    Date refDate = null;
    String refDateStr = null;

    if (null != request.getSession().getAttribute(BOOK_SLOT_SELECTED_DATE)) {
        final SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
        refDateStr = (String) request.getSession().getAttribute(BOOK_SLOT_SELECTED_DATE);
        try {
            refDate = timeService.getCurrentTime();
            refDate = sdf.parse(refDateStr);
        } catch (final ParseException pe) {
            LOG.error("Exception while parsing date " + refDate, pe);
        }

        final BookSlotForm bookSlotForm = populateBookSlotForm(request, response, refDate);

        LOG.debug("bookSlotForm getMorningSlots = " + bookSlotForm.getMorningSlots().size());
        LOG.debug("bookSlotForm getAfternoonSlots = " + bookSlotForm.getAfternoonSlots().size());
        LOG.debug("bookSlotForm getEveningSlots = " + bookSlotForm.getEveningSlots().size());

        int biggestListSize = 0;

        if (bookSlotForm.getMorningSlots().size() >= bookSlotForm.getAfternoonSlots().size()) {
            biggestListSize = bookSlotForm.getMorningSlots().size();
        } else {
            biggestListSize = bookSlotForm.getAfternoonSlots().size();
        }
        if (biggestListSize < bookSlotForm.getEveningSlots().size()) {
            biggestListSize = bookSlotForm.getEveningSlots().size();
        }
        model.addAttribute(bookSlotForm);
        model.addAttribute("dateSelected", new Boolean(Boolean.TRUE));
        request.getSession().removeAttribute(BOOK_SLOT_SELECTED_DATE);
        LOG.debug("End: fillModel");
    }
}

private BookSlotForm populateBookSlotForm(final HttpServletRequest request, final HttpServletResponse response, final Date refDate) {
    LOG.debug("Start: populateBookSlotForm");
    final BookSlotForm bookSlotForm = new BookSlotForm();

    bookSlotForm.setSelectedDate(refDate);
    bookSlotForm.setSelectedStr(refDate);

    bookSlotForm.setDayOfWeek(BookSlotHelper.getDayNameFromDate(refDate));

    Map<String, List<SlotData>> slotMap = new HashMap<String, List<SlotData>>();

    List<SlotData> morningSlotDataLst = new ArrayList<SlotData>();

    }

    bookSlotForm.setMorningSlots(morningSlotDataLst);
    bookSlotForm.setAfternoonSlots(afternoonSlotDataLst);
    bookSlotForm.setEveningSlots(eveningSlotDataLst);

    LOG.debug("Before: bookSlotForm.getSelectedSlotStr() = " + bookSlotForm.getSelectedSlotStr());

    if (null == bookSlotForm.getSelectedSlotStr()) {
        final SlotData selectedSlot = bookSlotFacade.getSelectedSlot();
        if (null != selectedSlot && null != selectedSlot.getSlotCode() && !"".equals(selectedSlot.getSlotCode())) {
            bookSlotForm.setSelectedSlotStr(selectedSlot.getSlotCode());

不要将整个 url 放入setPath调用中 - 只是您希望 cookie 有效的站点内的路径：

collectionPointCookie.setPath("/bookslot");

此外，路径必须包括设置 cookie 的 servlet 的路径 - 请参阅文档
