Spring boot: Hibernate аннотация

Question

Я начинаю весеннюю загрузку, и у меня возникла проблема с аннотацией ManyToMany и ассоциацией класса

У меня проблема с настройкой отношения один ко многим в моем аннотированном объекте.

Я впервые использую Hibernate и не могу заставить его работать со своей схемой. У меня есть следующее: изображение моей диаграммы: [1]: https://zupimages.net/up/19/19/9flp.png "Диаграмма"

the error is :

Answer 1

Я рекомендую вам блог Влада Михалча, я так много узнал о Hibernate. Здесь вы также можете найти примеры отношений ManyToMany

И вам следует избегать имен столбцов, как, например, joinColumns = { @JoinColumn(name = "id_foramteur") } вместо j oinColumns = { @JoinColumn(name = "idForamteur") }.

А с помощью Lombok вы можете избавиться от геттера и сеттера с помощью одной аннотации.
