ObjectiveSQL fournit un exemple complet pour diverses bases de données ci-dessous. Vous pouvez l'ouvrir directement avec IntelliJ IDEA en tant que projet autonome. En fait, ce ne sont pas seulement des exemples, mais aussi des tests unitaires d'ObjectiveSQL dans diverses bases de données.
Si vous souhaitez exécuter sans configuration, vous pouvez essayer : SQLite
Autres : MySQL, Oracle, MS SQL Server, PostgreSQL, Spring Boot
Vous définissez juste un JavaBean avec des annotations
