Я пытаюсь реализовать авторизацию, но не могу понять причину этой проблемы: *Encoded password does not look like BCrypt*.
Порядок моих действий: Открываю
localhost:8080/login, ввожу "user" и "password" в поля username и password (пользователь с такими данными существует в базе данных), нажимаю submit, тут появляется ошибка
Encoded password does not look like BCrypt (она отображается в консоли), и логин фейлится. Я не опытен в Spring, поэтому прошу Вашего совета.
Мне кажется, причина в строке
the auth.userDetailsService(userService).passwordEncoder(passwordEncoder()); в методе
protected void configure(AuthenticationManagerBuilder auth) в классе
WebSecurityConfig.java, но никакие решения из гугла мне не помогают.
