C'est mon erreur:

***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of method setProductService in com.ensat.controllers.ProductController required a bean of type 'com.ensat.services.ProductService' that could not be found.
Action:
Consider defining a bean of type 'com.ensat.services.ProductService' in your configuration.

J'en ai plein le journal: https://gist.github.com/donhuvy/b918e20eeeb7cbe3c4be4167d066f7fd

C'est mon code source complet
https://github.com/donhuvy/accounting/commit/319bf6bc47997ff996308c890eba81a6fa7f1a93

La façon de corriger l'erreur?

J'ai ajouté ProductServiceImpl dans la question puisque c'est le manque de haricot.
