jquery load传参数到controller

要格式化成字符串，否则可能无法传进去

$("#rh_div_right").load(globalContentPath + globalMenuUrl, {
            para: params//这个params一定是字符串格式
        }, function (responseTxt, statusTxt, xhr) {

            

        })

@RequestMapping("/templateInstHome2")
    public ModelAndView index2(@RequestParam("para") String params) {
        String urlMenu = "/ppc/templateInstHome";
        ModelAndView view = new ModelAndView(urlMenu);
        log.debug("访问首页");
        this.pri(urlMenu);
        return view;
    }
