The Java ecosystem is evolving faster than ever-and Spring Boot 4 marks the most significant shift in its history. Many developers sense that "things have changed," but few truly understand how deep the transformation goes. This book was created to bridge that gap.
Spring Boot 4 Projects and Best Practices is a practical, project-driven guide that helps developers master the new Spring Boot era-an era defined by Virtual Threads, Native Images, modular architectures, Jakarta EE 11, and an entirely new approach to building production-grade systems.
This book shows you exactly how to build in this new era-not with theory, but through 15 real, fully runnable projects that gradually unlock Spring Boot 4's most important capabilities.
