Скачать или смотреть Spring Boot + MySQL Integration | Connect REST API to Database | Spring Data JPA Explained (Part 3)

Welcome back to the Spring Boot Series – Beginner to Job Ready!
In Part 3, we upgrade our backend by connecting our Spring Boot CRUD REST API to a real MySQL database using Spring Data JPA, Hibernate, and ORM.
You’ll learn how JPA maps Java objects to database tables, and how our API creates, saves, and fetches data from MySQL with clean and production-ready code.
This step transforms your project from basic to scalable, real-world backend development.

In this video, you’ll learn:
✔️ How to set up and create a MySQL database (Workbench, XAMPP, or phpMyAdmin)
✔️ How to add MySQL Connector/J to create a bridge between Java & MySQL
✔️ How Spring Data JPA + Hibernate automatically generate queries
✔️ How Java classes are converted into actual database tables
✔️ How to insert, update, delete & fetch real data from MySQL
✔️ Why JPA makes database operations easier, cleaner, and faster

By the end of this part, your Spring Boot project will be fully connected to a permanent database, ensuring your data stays safe even after server restarts.

This episode is ideal for beginners, students, and anyone preparing for Java backend developer interviews or building real-world projects.
