Spring AI Engineering (Paperback)

Paperback. Connecting a Spring Boot application to a large language model is straightforward. Engineering an intelligent system that remains reliable, testable, secure, and ready for production is not. Spring AI Engineering is written for Java and Spring developers who need more than API examples. It is a practical guide to architecting, building, testing, and deploying generative AI applications with Spring AI from the first model interaction through retrieval-augmented generation, tool calling, workflows, and production operations. The book starts where serious work begins: understanding generative models as application components with distinctive latency, cost, and failure characteristics. Readers learn how to design prompts and context deliberately, produce structured outputs that application code can trust, and maintain conversational state without exhausting context windows. From there the material advances into embeddings, vector search, and Retrieval-Augmented Generation treated as an information-retrieval and systems problem not merely as loading documents into a vector store. Multimodal capabilities, tool calling, and the Model Context Protocol extend what applications can perceive and do. AI workflows and agentic patterns are examined with engineering judgment in the foreground: the simplest architecture that solves the problem is preferred, and autonomy is introduced only when it is justified. Later chapters address production architecture, testing and evaluation of non-deterministic behavior, observability, security threats such as prompt injection, and the practical steps of deploying and operating Spring AI systems under real constraints. The intended reader is a proficient Java or Spring Boot developer backend engineer, software engineer, or technical architect who already understands Spring fundamentals and is ready to incorporate large language models, RAG, tools, and related generative AI capabilities into enterprise applications. The book does not teach programming from scratch. It develops the architectural reasoning, implementation patterns, and operational discipline required to move from a working demonstration to a maintainable intelligent system. What distinguishes this material is its engineering-first progression. Readers do not only learn how to invoke models. They learn how to choose an appropriate AI architecture, ground responses in reliable knowledge, connect systems to external tools safely, decide when workflows or agents are warranted, evaluate quality over time, observe cost and latency in production, and protect applications and data. Conceptual foundations, design decisions, practical implementation, failure modes, and production considerations are woven through the journey so that each capability is understood in context. If the goal is to build generative AI applications with Spring Boot and Spring AI that can be trusted beyond the demo, this book provides a coherent path from foundations to production.
