findByUserIdAndPassword（userId，密码）;

Question

当我试图通过此查询获取记录时findByUserIdAndPassword（userId，password）;使用MongoRepository 但我总是在得到任何建议时都为空吗？

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginValidation(@RequestParam String userId,@RequestParam String password) {
        System.out.println("un"+userId);
        System.out.println("password"+password);
        Optional<TicketUserDto> ticketuser=ticketUserDao.findByUserIdAndPassword(userId, password);
}
