后台

@RequestMapping(value = "getAllChildByRId", method = RequestMethod.GET)
        public ModelAndView getAllChildByRId(String rId, Model model) {
            XLog.showLogInfo("rId = " + rId);
            ModelAndView modelAndView = new ModelAndView();
            try {
                List<ChildAndPropertyAndContent> list = mainService.getChildAndPropertyAndContent(rId);
                XLog.showLogInfo("list = " + list);
                modelAndView.addObject("rId", rId);
                modelAndView.addObject("list", list);
                modelAndView.addObject("childSize", list.size());
                /*if (list.size() == 0)
                    modelAndView.setViewName("/index");
                else*/
                modelAndView.setViewName("/main");
            } catch (Exception e) {
                modelAndView.addObject("error", e.getMessage());
                modelAndView.setViewName("/main");
                e.printStackTrace();
            }
            XLog.showLogInfo("modelAndView.getViewName()" + modelAndView.getViewName());
            return modelAndView;
        }

前台:

$.ajax({
                type: "GET",
                url: "<%=basePath%>main/getAllChildByRId?rId=" + id + "",
                async: false,
                dataType: "text",
                success: function (data) {
                    window.location.href = data;
                    /*if ("${childSize}" > 0) {
                    } else {
                        layer.msg("该节点下没有节点");
                    }*/
                },
                error: function () {
    
                }
            });

前台接收不到数据主要是dataType没有设置正确,同时应该减产ajax请求类型是否和后台一致
