Spring Data JPA Tutorial - #14 - save() Method | Save an Entity to the MySQL Database Table

Hi, welcome to the Spring Data JPA tutorial series/course.
In this lecture, we will learn how to save an entity to the database using the save() method.

Spring Data JPA is used to reduce the amount of boilerplate code required to implement the data access object (DAO) layer.

Spring Data JPA is not a JPA provider. It is a library/framework that adds an extra layer of abstraction on top of our JPA provider (like Hibernate).

Spring Data JPA uses Hibernate as a default JPA provider.

But Test methods shouldn't persist the data in db, it must rollback right?
