Learning Spring Boot 4: Simplify the development of production-grade applications using Java and Spring

Spring Boot 4 brings more than just the powerful ability to build secure web apps on top of a rock-solid database. It delivers Jackson integration, support for JSpecify, an enhanced retry mechanism, and updated actuator defaults, along with ways to squeeze out more efficient usage of existing resources.

This fourth edition of the bestseller starts off by helping you build a simple app, and then shows you how to secure, test, bundle, and deploy it to production. Then, you’ll familiarize yourself with the ability to go “native” and release using the latest version of GraalVM. As you advance, you’ll explore reactive programming and get a taste of scalable web controllers and data operations.

Additionally, this edition includes brand-new topics, including virtual threads, concurrency, and observability, as well as building intelligent applications with Spring AI.

If you want to gain a thorough understanding of building robust, modern applications using the core functionality of Spring Boot, then this is the book for you. By the end, you’ll be able to build an entire suite of web applications using Spring Boot and deploy them to any platform you need.
