Вопрос:
Привет, друзья, я работаю над платформой Hibernate.Я пытаюсь использовать @встроенную аннотацию в своем приложении, но я не понимаю, почему она не отображается для меня. Это мой код

For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Раньше все работало нормально, но когда я начинаю использовать @Embedded Annotation, моя консоль вывода выводит только это.
Заранее спасибо

1. извините, я ошибочно копирую прошлый тот же класс, который я исправляю сейчас
Ответ №1:
Вы скопировали тот же код в свои классы UserDetail и UserAddress… Итак, я не уверен, но, вероятно, вы забыли добавить тег @Embeddable в свой класс user address. Если бы вы могли поместить правильный код в UserAddress, вероятно, увидели бы что-нибудь еще

1. Я думаю, что есть проблема со стороны Mysql, но я не смог выяснить, что
