Spring Data JPA

In this section, we will introduce Spring Data JPA, starting with a single database table, and then adding more entities and working with relationships between them. We will build OneToMany and ManyToOne relationships, both unidirectional and bidirectional. Additionally, we will look at how these relationships affect serialization to JSON, and how to avoid recursive structures using annotations or Data Transfer Objects (DTOs).
