Course Description

This course supports both Spring Boot 2 and Spring Boot 3.

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.


Problem:

In typical three-layer Spring boot application architecture, we create three layers - Controller, Service, and DAO/Repository layer.

If we use JPA/Hibernate and 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 boilerplate 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 top of our JPA provider (like Hibernate). Spring Data JPA uses Hibernate as a default JPA provider.

A wonderful course by Ramesh. Covers in details all the topics in Spring Data JPA with excellent examples. A must course to master Spring Data JPA. The interview questions were like an icing on the cake.

By Christian Schneider on 5/22/2025

Der Moderator wirkt sehr kompetent in seinem Thema. Trotz indischer Herkunft ist sein Englisch gut zu verstehen. Die vorgestellten Themen behandeln auch tiefergehende Details, so dass man sich gut bewappnet fühlt, das erworbene Wissen in der Praxis anwenden zu können.

Very good course. This is the second course i completed after i completed the blog app course. Recommended for people who want to learn about the repository section in spring boot.

hi Ramesh it's really useful to get good concepts with hands on & i am looking for spring boot microservices with angular complete full stack project from your side.

This course is very beginner friendly but if you are looking to deep dive into Spring Data JPA then you need to explore those concepts on your own. I already had the basic understanding of Spring Data JPA so I was looking for some advance concepts to add on to my existing knowledge. If you have no idea of Spring Data JPA then this is a good course to take and also for those who need a refresher about the basics of JPA!!

Course was really good. Learned a lot from the course. I would suggest if some more examples could be considered in OneToMany and ManyToOne sections. Thanks

By Piotr Zawada on 12/30/2023

This is a very good introduction to Spring Data JPA, but repetitions are annoying. Every time a new repository is being created, the same explanations are provided relating JpaRepository and it's implementation or hierarchy. We already know it from first time and there is no reason to repeat it apart from artificially increasing the content. The same applies to tests from the last section, where tests like for repository methods with different types of queries doesn't really differ from unit test point of view, and thus the section could be limited to at most half of it. Additionally, OneToOne mapping is using misleading digrams from OneToMany relation (or opposite), thus making looking at them slightly uncomfortable, but since some knowledge of SQL or Hibernate is in prerequisites I would say it's cosmetics. I generally recommend this course.

Hello. First I say thanks to author for valuable information in this course. The course fully explains all the necessary information and I am satisfied with the result. But I want to add that the course can be made even better if you fill the database with data from the real world. I mean, if the database didn't have the names "product1", "product2", "product description1", "product description2", etc., but real several hundred records with full descriptions, it would be better for mastering information But apart from this nuance, the course is very useful.
