de quelques jours J'essaie de résoudre le problème qui se produit dans mon programme, j'ai essayé plusieurs façons de résoudre, mais rien n'a fonctionné. Voici la trace de la pile:Compilateur doesn 'voir bean créé

Toutes les idées ce qui est incorrect dans le code? Je serai très reconnaissant pour toutes les idées, parce que j'ai déjà perdu beaucoup d'heures à essayer de résoudre cela.
J'ai collé que dans mon datasource.xml, mais il est toujours la même erreur. Dois-je changer quelque chose? – Greg
Peut-être que le fichier datasource.xml n'est pas inclus dans votre contexte Spring. Comment allez-vous amorcer le printemps? Essayez-vous de le charger uniquement pendant les tests? – bdkosher
