SpringMVC 注释@PathVariable

@PathVariable 是用来获得请求url中的动态参数的：

　　 @ResponseBody
    @RequestMapping(value="/pointUpload/{userid}",method = RequestMethod.POST)
    public  Map<String,Object> pointUpload(HttpServletRequest request,HttpServletResponse response,
                                           @PathVariable(value="userid") Integer userid){
        Map<String,Object> resultMap = new HashMap<String,Object>();
        try{

        }catch (Exception e){
            e.printStackTrace();
        }
        return resultMap;
    }
