Bonjour,

Error creating bean with name 'articleRepository': Invocation of init method failed; nested exception is java.util.NoSuchElementException

C'est qu'il n'arrive pas à trouver l'interface ArticleRepository. Vérifie bien la valeur de ton base-package ou basePackages dans le cas d'annotation.

A+.
