throw new RequestException(Constants.CODE_ERROR_LOGIN);
}
UserInfo userExtInfo = userService.queryUserExtInfo(userInfo.getId());
request.getSession().setAttribute("user_id", userInfo.getId());
request.getSession().setAttribute("syb", userInfo.getSyb());
request.getSession().setAttribute("flag", userExtInfo.getFlag());
