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.
