JPA / Hibernate One to Many Mapping Example with Spring Boot

In this tutorial, we will learn how to define a one-to-many unidirectional mapping between two entities using JPA and Hibernate.

We create a Spring boot project from the scratch and we will implement the one-to-many mapping between two entities using JPA and Hibernate. We will use a MySQL database to store and retrieve the data.

The one-to-many mapping means that one row in a table is mapped to multiple rows in another table.

Excellent content, you can make a video, where you have tables with various relationships and teach how to map them in classes, I just have a problem like that.
