This page contains a list of Spring Data JPA tutorials and examples. The goal of the Spring Data JPA module is to significantly reduce the amount of boilerplate code required to implement data access layers for various persistence stores.
Important: All the Spring Data JPA Tutorials are upgraded to use Spring Boot 3 and Java 17.

Application Architecture
In typical three-layer Spring application architecture, we create three layers - Controller, Service, and DAO/Repository layer.
If we use JPA/Hibernate then write a lot of coding while implementing DAO/Repository layer.
Spring Data JPA provides a solution to reduce a lot of boilerplate code.
We can use Spring Data JPA to reduce the amount of boilerplate code required to implement the data access object (DAO) layer.
Spring Data JPA is not a JPA provider. It is a library/framework that adds an extra layer of abstraction on top of our JPA provider (like Hibernate).
Spring Data JPA uses Hibernate as a default JPA provider.Spring Data JPA: Getting Started Tutorials

API Mapping of Spring Data JPA and JPA
The SimpleJpaRepository class provides the default implementation of a Repository interface. SimpleJpaRepository class internally uses JPA EntityManager to map its methods with JPA EntityManager interface methods.
It is better to know which JPA EntityManager method is being called by methods of Repository interface (SimpleJpaRepository class ) of Spring Data JPA.
The JPA methods called the main methods of the Repository interface of Spring Data JPA are shown below.
