Challenge: Spring Data JPA

Problem statement

Assume you have an existing e-commerce application that manages Ebook data using Spring JDBC. The current implementation has direct SQL queries embedded within the repository, which makes the application tightly coupled and less maintainable. To address these issues, we need to refactor the application to use Spring Data JPA for data access, thereby adhering to modern best practices in data management.

Requirements

Your task is to refactor the existing application to integrate Spring Data JPA for Ebook management. The project structure and database schema are already defined, with an existing table named Ebook that stores Ebook information. You are required to update Ebook and configure Spring Data JPA repositories to perform CRUD operations using a different table named spa_ebook.

Note: Ensure data integrity and maintain current functionality throughout the migration to Spring Data JPA to prevent disruptions to the original application.
