瀏覽器后退按鈕支持

Question

單擊瀏覽器后退按鈕后，它將發送一個發布請求，瀏覽器不允許它再次發送一個發布請求，並且顯示一個關於重新提交頁面的確認信息，如何在使用Spring框架的Java中避免該頁面。

職位要求代碼如下。

@RequestMapping(method = RequestMethod.POST, params = "action=search_by_name")
public ModelAndView searchByName(@RequestParam("contactName") String contactName, HttpSession session, WebRequest request) {
    ModelAndView mav = new ModelAndView(determineSearchSummaryView(request));

    ContactSearchHelper helper = new ContactSearchHelper(contactName);

    // After all the selections they made lets filter out based on the limited Territories
    CustomerUser user = (CustomerUser) userService.getLoggedInUser();
    helper.preFilterTerritories(user.getTerritories());

    EntitySearchCriteria criteria = helper.asCriteria(searchService);
    addSummaryCounts(mav, criteria, searchService);

    Long savedSearchId = searchService.save(criteria, SavedSearchType.CONTACT, false).getId();
    helper.setSavedSearchId(savedSearchId);
    session.setAttribute(getSearchHelperParam(), helper);
    session.setAttribute("contactDiscovery", "false");
    addAccordionData(mav, null);
    addExtraModelData(mav);
    return mav;
}

您只需在POST到某些URL之后使用重定向 。 您可以使用redirect: prefix或RedirectView做到這一點。
