使用Spring MVC将ajax响应发送到另一个控制器

Question

我有一个视图，从我向Controller发送请求的位置，结果将响应返回到视图页面。现在我想将ajax响应传递给下一个Controller，但我不知道Controller中的响应类型是什么 这是我的ajax代码：

$.ajax({
                type: "POST",
                url: "<c:url value="/menu/menucheckout/${restaurant_menu.name}"/>",

                data : {"amount":amount, "orderoption" :orderoption, "date":date , "time":time ,'menuitemsArray': menuitemsArray ,'menuPriceArray': menuPriceArray , 'menuSpiceeArray': menuSpiceeArray , 'ItemQuantityArray': ItemQuantityArray },

                success: function(response){
                    console.log(response);

                     window.location.href = "/BistroServicesMenuApp/welcome/getordercheckout/"+response.model;
                }

            });

这是菜单控制器

@Controller
@RequestMapping(value = "/menu")
public class MenuController {

@Autowired
private MenuTypeService menutypeService;

@RequestMapping(value="/menucheckout/{restaurantname}" ,method = RequestMethod.POST )
@ResponseBody
public ModelAndView menucheckout(@PathVariable("restaurantname") String restaurantname , HttpSession session, HttpServletRequest request, HttpServletResponse response) throws SQLException, NamingException, IOException
{

        ModelAndView model = new ModelAndView("/welcome/getordercheckout");

        System.out.println("COMING IN menucheckout CONTROLLER" + restaurantname);

        System.out.println("orderoption" + request.getParameter("orderoption"));
        String amount = request.getParameter("amount");
        String orderoption = request.getParameter("orderoption");
        String date = request.getParameter("date");
        String time = request.getParameter("time");
        String[]  menuitemsArray = request.getParameterValues("menuitemsArray[]");
        String[]  menuPriceArray = request.getParameterValues("menuPriceArray[]");
        String[]  menuSpiceeArray = request.getParameterValues("menuSpiceeArray[]");
        String[]  ItemQuantityArray = request.getParameterValues("ItemQuantityArray[]");

        model.addObject("restaurantname", restaurantname);
        model.addObject("amount", amount);
        model.addObject("orderoption", orderoption);
        model.addObject("date", date);
        model.addObject("time", time);
        model.addObject("menuitemsArray", menuitemsArray);
        model.addObject("menuPriceArray", menuPriceArray);
        model.addObject("menuSpiceeArray", menuSpiceeArray);
        model.addObject("ItemQuantityArray", ItemQuantityArray);

        return model;

  }

}

现在这是第二个控制器＆＃34; OrderController＆＃34;：

@Controller
@RequestMapping("/welcome")
public class OrderController {

@Autowired
private OrderService orderService;

@RequestMapping("/getordercheckout/{response}")
public ModelAndView getOrderCheckOut(@PathVariable("response") ModelAndView response)
{
    ModelAndView model = new ModelAndView("/getordercheckout");
    model.addObject("response" , response);
    System.out.println("Response : " +response);
    return model;
} 

现在我想得到回复，但我不确定响应的数据类型是什么。

System.out.println打印此错误：

  ModelAndView: reference to view with name '[object Object]'; model is null

请帮助我，因为我是Spring MVC的新手。 提前谢谢。
