Я пытался реализовать кэширование, данные кэшируются в памяти, но не извлекаются из кеш -памяти, когда называют второй или третий раз, вместо этого они выбирают из БД каждый раз, когда вызывается. Вопрос в том, что почему он не получает кэшированные данные?
Какую ошибку я делаю? idk, если это возникает проблема < /p>

Optional user = userService.findById(enterpriseId);
if (user.isPresent()) {
List response = demandMvpJobDetailsService.getActiveJobDetailsWithStats(enterpriseId, page, size);
return new ResponseEntity(response, HttpStatus.OK);
} else {
