Bonjour
dans ta classe org.example.entities.Author l'attribut books n'est pas une Collection avec des générique càd Collection<Book> books; sinon faudra l'annoté avec @OneToMany(targetEntity=Book.class)
A+

Merci hibour , ca était résolu ,
Maintenant si tu veux m'expliqué c'est quoi la cause de cette erreur ,
est ce qu'il ne supporte pas JAVA 1.4 ?
ça sera encore très gentille .

Non ce n'est pas possible car les annotations ne sont apparues qu'à partir de java 1.5

Erreur Spring jpa [Data]
