springboot后端无法获取session

springboot后端无法获取session

原来代码

  @RequestMapping("sendSMS")
    public Result<String> sendSMS(@RequestBody TelCode telCode, HttpSession session){
        //获取手机号码
        String mobile = telCode.getMobile();
        String code = ValidateCodeUtil.generateValidateCode(6).toString();
        session.setAttribute(mobile,code);
        return Result.success("手机验证码发送成功");

    }
 @RequestMapping("loginByMobile")
    public Result<TelCode> loginByMobile(@RequestBody Map map, HttpSession session,TelCode telCode){
        String mobile = map.get("mobile").toString();
        telCode.setMobile(mobile);
        //获取验证码
        String code = map.get("code").toString();
        telCode.setCode(code);
        //获取Session中保存的验证码
        String codeInSession = (String) session.getAttribute(mobile);
        return Result.success("200","成功", telCode);
    }

使用 HttpServletRequest中的`

request.getServletContext().setAttribute(mobile,code);
String codeInSession = (String) request.getServletContext().getAttribute(mobile);

解决
