Don't look for a 300-page PDF yet. The framework is moving too fast (versions 0.8.x to 1.0.0 milestone releases). Instead, look for "Cookbooks" or "By Example" PDFs, which are more version-stable.
To follow along with the examples found in popular GitHub repositories, you need to initialize a standard Spring Boot 3.x application. Maven Dependencies
This is a story about , a lead developer at a fintech startup, who is tasked with integrating AI into their Java backend. It follows his journey from discovery on GitHub to creating a "Production-Ready" PDF guide for his team. 1. The GitHub Spark

Save these vectors into a VectorStore (e.g., Pgvector, Pinecone, Neo4j, Milvus).
is the definitive framework for Java developers looking to integrate generative artificial intelligence into enterprise applications. As AI moves from standalone Python scripts to robust enterprise architectures, Java developers need a structured, idiomatic way to build AI-powered systems.

Function calling empowers LLMs to interact with external enterprise systems. You can declare a standard Java java.util.function.Function as a Spring Bean, register it with Spring AI, and the LLM will automatically decide when to invoke it based on the user's intent. Defining the Business Logic Function
Next, they implemented the chatbot's business logic using Spring AI's conversational API. They defined intents, entities, and actions to handle various user queries. For example, when a user asks, "What's the weather like today?", the chatbot responds with the current weather conditions. Don't look for a 300-page PDF yet
