Spring AI: Complete Feature Guide & 30-Day Developer Learning Roadmap
Artificial Intelligence is rapidly becoming a core capability in modern enterprise software. Java developers and architects no longer need to stitch together fragmented AI SDKs or abandon the Spring ecosystem to build intelligent applications.
Spring AI changes that.
This pillar guide gives you a complete, structured overview of Spring AI, its features, and how developers can progressively master it over 30 days. Each section below represents a dedicated deep-dive blog you can explore individually.
Whether you’re a corporate Java developer, software architect, or student, this guide helps you understand what Spring AI offers and how to use it strategically.
What Is Spring AI?
models into Java and Spring Boot applications.
It supports:
Multiple AI providers (OpenAI, Azure OpenAI, Anthropic, etc.)
Chat models and embeddings
Vector databases
Retrieval Augmented Generation (RAG)
Tool/function calling
Observability, evaluation, and cost control
Spring AI follows the same philosophy that made Spring successful:
Reduce complexity, standardize patterns, and enable production-ready systems.
Why Spring AI Matters for Java Developers
No vendor lock-in
Familiar Spring Boot configuration
Enterprise-grade observability
Clean APIs over rapidly changing AI SDKs
Designed for real production systems, not demos
