сохраните временный экземпляр перед сбросом: com.bookstore.domain.security.UserRole.role -> com.bookstore.domain.security.Role

Question

Я следую учебнику о весенней загрузке .. Я получил эту ошибку: Причина: java .lang.IllegalStateException: org.hibernate.TransientPropertyValueException: объект ссылается на несохраненный временный экземпляр - сохраните временный экземпляр перед сбросом: com.bookstore.domain.security.UserRole.role -> com.bookstore.domain.security.Role
