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.

A practical 2027 guide for Java developers who want to go beyond syntax. Explore Spring Boot, Jakarta EE, REST, security, JVM performance, gRPC, AI, DDD, testing and architecture through concise, real-world chapters designed to help you build better fullstack systems.

A high-performance data access layer must resonate with the underlying database system. Knowing the inner workings of a relational database and the data access frameworks in use can make the difference between a high-performance enterprise application and one that barely crawls.

Jetpack Compose是Android界面开发的未来。掌握其内部工作原理，让您成为更高效的开发者。即使您不是Android开发者，这本书对您来说也很有价值。本书详细介绍了Compose编译器和运行时的工作原理，以及如何使用它们创建客户端库。

A good software architecture should keep the cost of development low over the complete lifetime of an application. This book discusses how the Hexagonal Architecture style tries to fulfill this goal and translates the concepts into actual code to provide inspiration for software developers.

By the author of "Thinking in Java," covering version 8 of the Java programming language (with updates to Java 17). Intended for “dedicated beginners,” it doesn’t assume you know anything about programming and takes you through the material step-by-step. However, I assume you are able to figure things out. It’s not a “dummies” or “idiot’s” guide.

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.

The book about advanced Kotlin features most of us use, but nearly nobody understands, like variance modifiers, property delegation, interface delegation, contracts, multiplatform development, annotation processing, KSP, compiler plugins, and static analyzers.

A master class on the fundamentals and principles of functional programming. It contains 20 programming challenges with detailed solutions and 44 quizzes with answers and explanations. Moreover, 84 diagrams graphically illustrate how concepts and techniques work. Two real-world use cases show how to apply functional programming in practice.
