Comment utiliser spring roo pour gérer plusieurs DB?

Question

Je travaille sur un projet en utilisant spring roo et il doit gérer plusieurs DB. J'ai donc mis en place plusieurs sources de données et des usines de gestionnaires d'entités. Et quand je lance le projet, je reçois toujours l'erreur suivante:

Tous les objets de domaine, les classes de dépôt et de service sont générés par roo.

Y a-t-il quelqu'un qui peut m'aider avec ça?

Merci d'avance!

Answer 1

Si vous lisez attentivement ce message d'erreur très longtemps alors vous pouvez comprendre la racine du problème:

• Spring Security tente d'initier filterChainProxy
• processus d'initiation échoue, car il ne peut pas charger platformServiceDistributorFilter
• platformServiceDistributorFilter ne peut pas être créé car Spring ne peut pas générer automatiquement le champ de type ApplicationCatalogueService
• ApplicationCatalogueService ne peut pas être auto-signé car le ressort ne peut pas créer applicationCatalogueServiceImpl
• applicationCatalogueServiceImpl ne peut pas être créé car ne pouvait pas lier automatiquement ApplicationCatalogueRepository
• Enfin, le printemps ne peut pas créer ApplicationCatalogueRepository parce que quand il essaie de lier automatiquement le terrain avec le type javax.persistence.EntityManagerFactory a trouvé 5 différents haricots avec ce type dans le contexte de l'application

Avez-vous essayé de spécifier explicitement lequel de EntityManagerFactory vous voulez faire passer automatiquement à ? (Probablement en ajoutant l'annotation @PersistenceUnit avec le nom d'unité de persistance approprié.)
