Я создаю небольшой api с Spring Boot, Spring Security, Thymeleaf. Я создал рабочий логин, роли безопасности и теперь пытаюсь выполнить регистрацию. Если я добавлю новые (правильные для моей базы данных) данные, то пользователь будет создан правильно, однако я выполнил некоторые классические проверки в CrmUser, такие как @Notnull и мои собственные — проверки электронной почты и сопоставление паролей. Все они не работают. Я не знаю почему. Единственное, что работает, это «имя пользователя уже существует» из моего метода контроллера. Кто-нибудь может помочь?
