400 Hibernate @Valid的错误请求

尝试将代码更改为

@RequestMapping(value = CACHE_REMOVE, method = RequestMethod.POST)public String removeCachedElement(ModelMap model, @Valid @ModelAttribute(FORM_NAME) RemoveCacheElementForm form, BindingResult bindingResult) {    model.addAttribute("removeElementResult", CacheUtils.removeCachedElement(form.getName(), form.getKey()));    initializeModel(model);    return CACHE_ADMIN_PAGE;}
