Why take this course?
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.

All lessons are very detail. I learn a lot about Spring Data JPA and Hibernate from this course. But sometimes, knowledge may be repeated or no need to talk then it makes course longer.

Language accessible even to non-English speakers, and pace appropriate to the purpose of the course. Highly recommend!

This is a basic course. It doesn't cover all the concepts that are required for you in the real world. The knowledge of this course alone is not enough for you to work on complex projects.

Good Course. It's a practical real time course you have to apply these skills when working in company.

The overall course content is good. Thanks to make everything easy to understand. However, from my observation, I have points that could make the course better. He cover the same topic again and again, creating projects, repositories, and models were instructed on how could we do that but he made different lectures for these making the course content long.
Some statements are repeated multiple times. Never tried to give any deep explanation. I feel some places I need some extra explanation but that was missing. However, the basic concept got covered nicely.
Thanks

The course was great, the concepts were covered adequately and the instructor uses repetition to cement the concepts. It was great.

This is a really good course to understand how to use Spring Data JPA to build DAO layer of your application. All important concepts are well explained and demonstrated via a working example.
One small point I have is that all the tests (using @SpringBootTest) written as part of hands-on labs are not real unit tests because they are not using any assertions. If you are writing unit tests or integration tests then kindly make sure they do what they are suppose to.
Other than this small point, I really liked this course and recommend in highly to anyone interested in learning basics of Spring Data JPA and some more.

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.

Talking to fast. Well if you are natural English speaker then you can talk like a formula 1 driver drives but when you have a pretty strong foreign accent then it is pretty hard to understand.
