Java Spring Boot JPA | Hibernate | OneToOne Mapping | Lombok | 2021 | Part 1

In this tutorial we cover the Java Persistence API using Hibernate with Spring Boot Data JPA, focusing on the one-to-one relationship for both unidirectional and bidirectional relationships.

In part 2 of this video we cover mappedBy vs @JoinColumn and @JoinTable.

The Java Persistence API (JPA) is a Java specification for accessing, persisting, and managing data between Java objects / classes and a relational database.
JPA is now considered the standard industry approach for Object to Relational Mapping (ORM) in the Java Industry.
JPA is specification, and requires an implementation.
JPA also defines a runtime EntityManager API for processing queries and transaction on the objects against the database.
