The era of choosing between the simplicity of blocking I/O and the performance of Reactive Streams is over. Unlock the full potential of Java 25 and Spring Framework 7 to build the next generation of high-throughput, low-latency enterprise applications. For over a decade, Java developers have faced a painful trade-off: write simple, blocking code that hits a scalability wall, or adopt complex reactive frameworks like WebFlux that make debugging a nightmare. With the arrival of Java 25 LTS and Spring Boot 4 , that dichotomy is dead. In Maximizing Spring Framework 7 with Java 25 , Yan Zhu delivers the definitive architectural playbook for the post-Loom era. This is not just a syntax guide; it is a deep-dive into the mechanical sympathy required to build systems that exploit modern hardware to its limit. Whether you are migrating a legacy monolith or designing a cloud-native microservice from scratch, this book provides the empirical evidence and production-ready patterns you need. What You Will Learn: Master Virtual Threads (Project Loom): Learn to configure Tomcat and Jetty for infinite concurrency without the complexity of reactive chains. Understand the mechanics of carrier threads, continuations, and how to avoid the "pinning" trap that kills performance. - Harness Hardware Acceleration (Vector API): Go beyond standard loops. Implement SIMD (Single Instruction, Multiple Data) algorithms to accelerate financial modeling, cryptography, and image processing by orders of magnitude. - Escape the Heap (Project Panama): Utilize the Foreign Function & Memory (FFM) API to build zero-copy network buffers and interact with native C/C++ libraries safely, banishing JNI overhead forever. - Optimized Data Access: Re-architect your persistence layer. Discover how to tune HikariCP for virtual threads, leverage R2DBC for hybrid streaming, and fix Hibernate/JPA lazy-loading bottlenecks. - Next-Gen Observability: Replace expensive ThreadLocal hacks with Java 25 Scoped Values . Implement high-performance tracing with OpenTelemetry and Micrometer that survives across millions of threads. - Resilience at Scale: Adapt classic patterns like the LMAX Disruptor , Circuit Breakers, and Bulkheads for a world where threads are cheap but downstream resources are not. - GraalVM & AOT: Navigate the trade-offs between the Just-In-Time (JIT) compiler and Native Images for serverless and scale-to-zero deployments. Who This Book Is For: This guide is essential for Senior Java Developers , Software Architects , and Backend Engineers who want to stay ahead of the curve.
