Spring Hibernate Configuration
DOWNLOAD SOURCE CODE HERE⬇️ (SpringORM Configuration)
This project serves as a fundamental exploration of Spring ORM configuration, designed to provide a foundational comprehension. There are CRUD (Create, Read, Update, Delete) function avilable to play with the application. It will to gain insight into the operations facilitated by the HibernateTemplate class.
