2.后端：

@RequestMapping(value="/setRand",method = RequestMethod.POST)
 @ResponseBody
 @ApiOperation(value = "设置验证码成功")
 //@ApiImplicitParam(paramType = "query",name= "username" ,value = "用户名",dataType = "string")
 /*public void userLogin(@RequestParam(value = "username" , required = false) String username,
       @RequestParam(value = "password" , required = false) String password)*/
 public Message setRand(@RequestBody JSONObject json,HttpServletRequest request){
  Message message = new Message();
  String rand = json.getString("rand");
  if(StringUtils.isNotBlank(rand)){
   // 将认证码存入redis
   HttpSession httpSession = request.getSession();
   redisUtil.set(httpSession.getId() + ".rand",rand);
   redisUtil.expire(httpSession.getId() + ".rand",60);
   message.setSuccess(true);
  }else{
   message.setMessage("发生异常，请刷新重试");
  }
 
  return message;
}

3.登录验证时：

// 验证验证码
 String randInput = json.getString("rand");
 String rand = (String) redisUtil.get(httpSession.getId() + ".rand");
 
    if(randInput==null||!randInput.equals(rand)) {
     message.setMessage("验证码验证失败");
     // 清空验证码
     redisUtil.set(httpSession.getId() + ".rand","");
     return message;
 }
