SpringMVC 注释@PathVariable

@PathVariable 是用来获得请求url中的动态参数的：

 1 　　 @ResponseBody
 2     @RequestMapping(value="/pointUpload/{userid}",method = RequestMethod.POST)
 3     public  Map<String,Object> pointUpload(HttpServletRequest request,HttpServletResponse response,
 4                                            @PathVariable(value="userid") Integer userid){
 5         Map<String,Object> resultMap = new HashMap<String,Object>();
 6         try{
 7 
 8         }catch (Exception e){
 9             e.printStackTrace();
10         }
11         return resultMap;
12     }
