Top 5 Courses to Learn Spring Data JPA Courses in 2024 - Best of Lot

Hello Java programmers, if you want to learn Spring Data JPA in 2024 and looking for the best online courses then you have come to the right place. Earlier, I have shared my favorite courses to learn different projects under Spring frameworks like Spring Boot, Spring Cloud, Spring Security, Reactive Spring + WebFlux,  and Spring MVC and in this article, I am going to share the best Spring Data JPA courses for beginners and experienced Java developers. Spring Data JPA is part of Spring Framework and it really makes it easy to work with JPA providers like Hibernate and EclipseLink. It can greatly improve developer productivity if used correctly.

If you are thinking what is JPA and Spring Data JPA then let me tell you that JPA stands for Java Persistence API which is a Java standard for defining persistence layer and Spring Data JPA is a sub-project under the Spring Framework umbrella which allows Spring applications to integrate with JPA.

Contrary to the popular Myth that it's a JPA implementation like Hibernate, it actually provides another level of abstraction to produce more cleaner code and it always needs a JPA implementation like Hibernate and EclipseLink to work with.

If you are thinking what is the point of using Spring Data JPA if you have to use Hibernate or Eclipse Link then let me tell you that its a kind of add-on, it makes it easier to write your Data Access Layer and provides clean methods to save and retrieve data from any Database without writing SQL.

Spring Data JPA comes with a concept called JPA Repository and Query methods. JPA Repository is nothing a set of interfaces that defines query methods like findByFirstName or findByLastName etc. These methods are converted into low-level SQL queries by Spring. 

This means you don't need to write SQL queries anymore, those will be generated automatically for you, but at the same time, if you want to control you can still write JQL queries that are portable across the database vendors like MySQL, Oracle, Microsoft SQL Server, and PostgreSQL.

If you are wondering how does it work then think about the Proxy pattern. Spring Data JPA just defines a Repository interface that has methods for saving and retrieving data from Database and populating your Entity objects like User, Books, Order, etc. Spring does all the heavy lifting by providing implementation at runtime with very minimal work from the developer side.

Because of this cleaner approach, many Spring based applications are using Spring Data JPA to implement their Data Access Layer or DAO Layer and that's why it makes sense to learn Spring Data JPA in 2024.

When it comes to learning Spring Data JPA in 2024, online courses and books are two main ways, unfortunately, there are not many Spring Data JPA courses available online, particularly when you compare to the amount of Spring Boot courses, but I have done the hard work for you and curated best Spring Data JPA courses from sites like Udemy, Baeldung and others. 

These courses are comprehensive, up-to-date, and affordable, and useful for both beginners and experienced Java developers who want to learn Spring Data JPA from scratch.
