Question

我遇到RedirectAttributes没有保存的问题（我认为）。这是我的代码：

@RequestMapping(path = "/job_offers", method = RequestMethod.POST)
    public String createJobOffer(@Valid @ModelAttribute("jobOfferForm") JobOfferForm jobOfferForm,
            final BindingResult binding, RedirectAttributes attr) {
        attr.addFlashAttribute("org.springframework.validation.BindingResult.jobOfferForm", binding);
        attr.addFlashAttribute("jobOfferForm", jobOfferForm);

        return "redirect:/job_offers";
    }

@RequestMapping(path = "/job_offers", method = RequestMethod.GET)
    public ModelAndView jobOffers(@RequestParam(required = false, value = "skill_id") final Long skillId,
            @ModelAttribute("jobOfferForm") JobOfferForm jobOfferForm, final BindingResult binding) {

        ModelAndView mav = new ModelAndView("job_offers/index");

        mav.addAllObjects(getJobOffersMap(skillId));
        mav.addObject("jobOfferForm", jobOfferForm);

        return mav;
    }

如果我在POST方法中打印我的绑定它有错误，但是当我通过重定向调用GET方法时，绑定变为空！和Spring没有显示表单上的错误反馈

有什么想法吗？谢谢！

试试这个：在你的POST中

swagger: '2.0'

info:
  version: 1.0.0
  title: Form data API
  description: Using form data body parameters

paths:

  /examples:
    post:
      consumes:
        - application/x-www-form-urlencoded
      parameters:
        - name: grant_type
          type: string
          in: formData
        - name: client_id
          type: string
          in: formData
        - name: client_secret
          type: string
          in: formData
      responses:
        200:
          description: OK

在GET中

 attr.addFlashAttribute("bindignResultForJobOfferForm", binding);
