Я решил использовать Spring JDB C Session для хранения зарегистрированной информации о пользователе. Сущность «Пользователь» включает поле «фото» типа «Строка». На самом деле, я храню изображения профиля пользователя в базе данных в виде строки в кодировке Base64. Информация о пользователе хранится в базе данных без каких-либо проблем. Spring JDB C сеанс может содержать информацию о пользователе, включая фотографию размером 20 КБ. Но когда пользователь с фотографией размером 52 КБ хочет войти, он выдает ошибку -
There was an unexpected error (type=Internal Server Error, status=500).
