Spring Data JPA Tutorial

Introduction

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.

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 the Repository interface (SimpleJpaRepository class) of Spring Data JPA.

The JPA methods called by the main methods of the Repository interface of Spring Data JPA are shown below:
