The official GitHub repository for the code examples from the book Spring AI in Action
by Craig Walls is hosted at habuma/spring-ai-in-action-examples. This repository includes the sample code as it appears in the printed book (built against Spring AI 1.0.3), while updates for newer versions like Spring AI 1.1.0 are maintained in a secondary repository, habuma/spring-ai-in-action-samples.
Regarding the PDF version, there is no official, legal PDF of the book available for free on GitHub. The book is a commercial publication available through Manning Publications and O'Reilly Media. Key GitHub Repositories
Main Example Repository: Contains the original code from the book's manuscript.
Updated Samples Repository: Intended for future updates and cleaner formatting post-printing.
Spring AI Framework Official Repo: The source for the underlying Spring AI framework itself.
Spring AI 101: A community showcase project that demonstrates "Spring AI in action" through practical features like RAG, image generation, and function calling. PDF and Documentation Status
Book PDF: Access to the full PDF version typically requires purchase from the publisher. spring ai in action pdf github link

Example Use Cases:
The book "Spring AI in Action" by Craig Walls is the definitive guide for Java developers looking to integrate generative AI features into the Spring ecosystem. Published by Manning Publications , it bridges the gap between enterprise Java reliability and the power of large language models (LLMs). 📚 Book Resources & GitHub Links
For those searching for official code and documentation, the following resources are essential:
Official Example Code: The primary repository for the book's examples is hosted on GitHub at habuma/spring-ai-in-action-examples .
Alternative Sample Code: A secondary repository for cleaned-up samples is maintained at habuma/spring-ai-in-action-samples .
PDF Access: While unofficial PDF copies sometimes appear on GitHub, Manning provides a legitimate free eBook (PDF, ePub, and Kindle) included with any purchase of the print edition.
Reference Documentation: The official Spring AI Reference Documentation provides a comprehensive HTML guide, though an official downloadable PDF from the Spring team is still a pending community request. 🛠️ What You Will Learn in "Spring AI in Action"
The book follows a practical, "in action" approach, taking readers from "Hello AI" to production-ready services: habuma/spring-ai-in-action-samples - GitHub The official GitHub repository for the code examples
Since "Spring AI" is a relatively new and rapidly evolving project, there isn't a classic, published O'Reilly or Manning book simply titled "Spring AI in Action" just yet.
However, if you are looking for the definitive hands-on guide (a "Spring AI in Action" style resource) with code examples and a PDF reference, here is the best available solid guide.
| Pitfall | How the GitHub Repo Helps |
| :--- | :--- |
| API Key management | Look at application.properties samples. Use spring.ai.openai.api-key=$OPENAI_API_KEY |
| Model version mismatches | The repo uses specific, tested versions (e.g., gpt-3.5-turbo). Stick to those. |
| Function calling not working | Check the FunctionCallbackWrapper examples in spring-ai-examples. You must register the function as a Spring bean. |
| Vector store connection | The spring-ai-examples includes docker-compose files for Pgvector – run docker-compose up first. |
git clone https://github.com/spring-projects/spring-ai.git
cd spring-ai
Since "Spring AI in Action" doesn't exist as a specific title yet, here is the best way to get the content you want:
| What you are looking for | Best Link | | :--- | :--- | | Source Code / Examples | github.com/spring-projects/spring-ai | | PDF Book (MEAP) | Manning Books Search (Search for "Spring AI") | | Quick Start Guide | Spring AI Reference Docs |
If you meant a specific GitHub repository created by a community member (e.g., a tutorial repository named spring-ai-in-action), please verify the exact author, as several community tutorials exist with similar names.
The fastest "in action" experience is using Spring Boot CLI: Spring AI : Spring AI is a part
spring init --dependencies=spring-ai-openai,web my-ai-app
cd my-ai-app
# Add your API key to application.properties
