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;
     }
