Spring MVC 提交带有点分隔的参数

 @InitBinder("orderTargetingsVo")
    public void initBinder(WebDataBinder webDataBinder) {
        webDataBinder.setFieldDefaultPrefix("targeting.");
    }

    @ResponseBody
    @RequestMapping("/add.do")
    public Map<String, Object> addAdOrder(AdOrderVo adOrderVo, OrderTargetingsVo orderTargetingsVo) {

        result.put("msg", "操作成功！");
        result.put("success", true);
        return result;
    }
