您需要将所有JSTL值设置为具有专有名称/ID的输入标记（隐藏类型）。然后，您可以通过使用访问控制器中的隐藏输入

request.getParameterValues（“hiddenInputId”）
@RequestMapping(value="/atc/edit", method=RequestMethod.POST)
public ModelAndView editATC(@ModelAttribute("message") String message, HttpServletRequest request, HttpServletResponse response) throws ServletException
{
    System.out.println(request.getParameter("action"));
    System.out.println(request.getParameter("atcId"));
    ModelAndView mav = new ModelAndView();
    mav.setViewName("view_ATCMaster");
    mav.addObject("message", message);
    return mav;
}
