Я попытался установить двунаправленное отношение @OneToMany (одна авиакомпания имеет много приложений) при запуске airlineRepository.findAll() вместо одного выбора всех запросов в режиме гибернации делает это навсегда и вылетает приложение:

Это не из-за Hibernate, а из-за ваших аннотаций Lombok: 

@ToString
@EqualsAndHashCode

При использовании этих аннотаций вы должны быть осторожны, чтобы не получить бесконечные циклы. Например, если вы вызываете toString () для entity1, вызывается toString () для entity2, который снова вызывает toString () для entity1 и т. Д. c ..

Либо удалите эти аннотации, если вы их не используете или настройте их так, чтобы не возникало бесконечных циклов.
