This book is about JPA, Hibernate, and Spring Data; our focus is on using Hibernate as a provider of the Jakarta Persistence API (formerly Java Persistence API) and Spring Data as a Spring-based programming model for data access. We’ll cover basic and advanced features and describe some ways to develop new applications using the Java Persistence API. Often these recommendations aren’t specific to Hibernate or Spring Data. Sometimes they’re our own ideas about the best ways to do things when working with persistent data, explained in the context of Hibernate and Spring Data.
