Spring Boot 4 changes everything you thought you knew about building Java applications. Virtual threads make blocking code fast again. Native images deliver instant startup. First-class API versioning finally solves the "how do we evolve our APIs?" problem. But here's the catch: upgrading isn't just a dependency bump. Jakarta EE 11, new auto-configuration patterns, GraalVM constraints, and reactive vs. virtual threads— getting it right requires understanding the *why* behind every change. This book is your production-ready guide to Spring Boot 4 and Spring Framework 7. Written for intermediate developers who need more than "hello world" tutorials. Learn how to: • Build cloud-native microservices that scale • Migrate from Boot 3 safely and incrementally • Design APIs with built-in versioning and resilience • Choose between reactive, virtual threads, and native images • Secure distributed systems with JWT and OAuth2 • Implement observability that actually helps you debug production issues 300+ pages. 27 chapters. Real code. Real architecture. Real problems solved.

Java has changed. Have your patterns kept up?The Gang of Four wrote their landmark patterns in 1994 — when Java didn't exist, generics were a decade away, and "concurrency" meant carefully managing a handful of platform threads. Thirty years later, Java 21 through 25 has transformed the language: records replace boilerplate classes, sealed interfaces model closed type hierarchies with compiler enforcement, pattern matching eliminates entire categories of unsafe casting, and virtual threads make a million concurrent tasks not just possible but routine.Modern Java Design Patterns bridges that gap. Every classic pattern is shown first in its original form, then systematically rebuilt with the language features that exist today. The result is code that is shorter, safer, more expressive, and immediately recognisable to any team working on a modern Java codebase.

Jetpack Compose is the future of Android UI. Master how it works internally and become a more efficient developer with it. You'll also find it valuable if you are not an Android dev. This book provides all the details to understand how the Compose compiler & runtime work, and how to create a client library using them. You could also be interested on the Jetpack Compose Internals course by Jorge Castillo. Find it in composeinternals.com

The fastest code you will ever write is the code you already have, tuned correctly.

O Jetpack Compose é o futuro da UI do Android. Domine como ele funciona internamente e torne-se um desenvolvedor mais eficiente com ele. Você também achará útil mesmo se não for um desenvolvedor Android. Este livro fornece todos os detalhes para entender como o Compose compiler e o runtime funcionam, e como criar uma biblioteca cliente usando-os.

if you've read my chapter on naming in a famous software book (first or second edition) you may want to go a little deeper. Same author, same topic, all-new content!

Join Spring Developer Advocate Josh Long (@starbuxman) for an introduction to reactive programming and its implementation in the Spring ecosystem.

Most developers treat Hibernate as a black box that turns objects into rows. This book opens the box, shows you exactly what happens inside, and teaches you how to make it work for you at scale.

Build a complete, production-grade microservices platform with Spring Boot 4 and Java 21, one chapter at a time.

Write code that you can understand without holding the entire system in your head. This book shows you how Java's modern functional features—records, sealed types, lambdas, streams—combine into a powerful approach to design. You'll learn: • How to eliminate race conditions without synchronized blocks • How to write tests that test business logic, not mock frameworks • How to compose complex behaviors from simple, reusable functions • How to manage deeply nested immutable data without boilerplate • How to adopt functional patterns incrementally in existing codebases Written for working developers. Filled with production-ready code examples.

Get started with the latest versions of Java, JavaFX, Pi4J, Spring, and so much more. Learn the power (and fun!) of experimenting with electronics. All explained in many small and easy-to-understand examples.

In this book key contributors to the JavaParser library teach you how to programmatically analyse, transform and generate your java code base. The first part of the book aims to introduce you to the basics of the library before the team take you through a more detailed look at some of their favourite applications of the library.

Model Context Protocol (MCP) servers with Java and Spring Boot allow you to standardize how your applications connect to AI assistants and LLMs by exposing internal data and functions as structured, tool-based endpoints. By leveraging the Spring AI framework, you can easily implement MCP protocols to securely bridge your business logic with intelligent agents. This approach simplifies integration, enabling your services to be dynamically discoverable and actionable within an AI-driven ecosystem.

Программирование всегда доступных, распределенных, обслуживающих миллионы запросов систем основано на возможностях облаков Cloud. Книга расскажет, как создавать приложения согласно концепции Cloud Native, "рожденные" жить и работать в облаке - а именно видеть их как набор микросервисов, упаковывать в образы Docker, и управлять ими в Kubernetes.
