10 Spring Framework Books Experienced Java Developers Should Read in 2025 - Best of Lot

The Spring framework has changed a lot in the last couple of years. We have seen significant releases for Spring, Spring Boot, and Spring Security. These new releases introduced several exciting features to meet the latest software development trends, like Reactive programming, support for Kotlin for developing Spring applications, Spring WebFlux - a new framework to build non-blocking and reactive web applications,  and many more. Since the software world is changing and most of the development is happening on Cloud with Microservice architecture leading the way, it's high time that experienced Java developers should upgrade themselves.

If you have been using Spring for years but haven't got a chance to got-up with all the latest development in the Spring world, then the year 2025 is the best time to correct that.

After the Java SE 8 release, most of the Java frameworks are upgraded to support the new style of coding in Java. It has now become standard in Java, and the code written using the old method is no more in practice.

Technical lead and architect are rejecting such code in peer code review and encouraging experienced Java developers, like someone who has 5 to 8 years of experience to learn Java 8 and Spring 5.

It makes sense; you just can't write code in the old way if a better option is available, which is more readable, intuitive, and provide better performance. The same goes for the Reactive programming model.

Well, I will accept that once you gain experience, your learning becomes slow, and many Java developers, including myself, don't put enough effort into keeping ourselves up-to-date.

Your company also plays an essential role in this, for example, if you are working for Investment banks and big organization which is still using old technologies then you will be less likely to upgrade yourself because there is no push. 

If you are working for a startup, which is very agile in adopting the latest and greatest framework, library, and technology, you will likely upgrade yourself more often.

Btw, if you are entirely new to Spring world and looking for the best way to learn the Spring framework in 2025, then I suggest you first start with a comprehensive online course like Spring Framework 6: Beginner to Guru before you read this book. I have found that it accelerates your learning, and you get more from the books later.

10 Best Spring Framework Books for Java developers in 2025

Anyway, if you want to give your career a boost and break the shackle, here are a couple of Spring books, I think experienced Java developers should read to learn about new features of Spring 5, Spring Boot, Spring Cloud, and how to develop Java application for Cloud using spring frameworks.

In the last couple of years, there are a few more great Spring books cam along which are great for anyone who wants to master advanced topics like Reactive Spring, Security, and Spring Boot in depth. Apart from these books, I have included  few more spring books that are worth looking at in 2025

You can read these books to further improve your knowledge of Spring Framework and become a better Java developer in 2025.

Now, let's see my list of classic Spring Framework books which are still worth reading in 2025. 

1. Spring in Action 6th Edition

This should be one of the first few books to read in 2025, of course, only after you finish the Effective Java 3rd edition if you haven't already.

Though Spring in Action doesn't need any introduction or recommendation and is hands down the best book to learn Spring framework now, it is also updated to Spring 5.3which means you can use this to learn and discover what’s new in Spring Framework 5, like Reactive features, WebFlux, etc.

It will also teach you how to use the Spring Framework with Java 9 and aster data access and transactions, work with the new functional web framework and create microservices and other web services using Spring Boot and other cloud technology.

I suggest you follow this book if you are learning the Spring framework in 2025. It's more up-to-date and follows the latest practices for developing a Java application with Spring. If you want, you can also combine this book with Spring Framework 6: Beginner to Guru course on Udemy, which is also the most up-to-date course to learn Spring framework in 2025.

2. Reactive Spring by Josh Long

If you are looking for a book to learn Reactive programming with Spring Framework then this is one of the best Spring books you can read in 2025. "Reactive Spring" by Josh Long offers a comprehensive exploration of reactive programming within the Spring ecosystem, presenting an essential guide for developers grappling with the challenges posed by microservices and big data.

Josh Long, a seasoned Spring Developer Advocate, delves into the limitations of traditional input/output models, particularly in the context of IO-bound work dominating threads.
