Learn Spring Data JPA with Hibernate: The Masterclass

In this course, you will learn how to use Spring Data JPA and its features to reduce a lot of boilerplate code.

Throughout this course, we will build domain model entities (Product, ProductCategory, Order, OrderItems, User, Roles) and repositories for a simple e–commerce application.

The source code and PDF files (class notes) are available for download.

Problem:

In typical three–layer Spring boot 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 – We repeat the same code again and again so what will be the solution to reduce the boilerplat code.

Solution:

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 the top of our JPA provider (like Hibernate). Spring Data JPA uses Hibernate as a default JPA provider.
