浏览器后退按钮支持

Question

单击浏览器后退按钮后，它将发送一个发布请求，浏览器不允许它再次发送一个发布请求，并且显示一个关于重新提交页面的确认信息，如何在使用Spring框架的Java中避免该页面。

职位要求代码如下。

@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做到这一点。
