These demos have been built using JDK 17, Hibernate 6. While it is recommended to have JDK 17 installed, the examples can be adapted to other Java versions with minimal modifications.
The database used in these examples is MySQL, but the code can be adjusted to work with other databases if needed.
Before diving into Hibernate, ensure you're comfortable with the following concepts:
You can learn these topics from my YouTube channel through dedicated playlists.Follow these steps to set up and execute the demos:
- Clone the repository.
- Import the project into your preferred IDE as a Maven Project.
- Configure the database connection, if necessary.
- Run the application and test the methods.
If you're a beginner, it's best to execute the demos in the given order to build your understanding progressively. If you're experienced, feel free to explore specific demos based on your needs.
These demos are explained in detail on my YouTube channel Abhishek Verma. Watch the complete playlist here: Hibernate.
