Spring Ai In Action | Pdf Github

The team decided to use the following technology stack:

// Splitting the document into manageable chunks var textSplitter = new TokenTextSplitter(); var splitDocuments = textSplitter.split(documents);

The Java ecosystem is undergoing a massive shift. For years, Python was the undisputed king of AI and LLM integration. But with the release of , Java developers are finally getting a first-class, production-ready framework to build AI-powered applications without switching languages.

The intersection of enterprise Java (Spring Boot) and Generative AI is no longer a futuristic concept—it’s a present-day necessity. As developers scramble to integrate Large Language Models (LLMs) like OpenAI’s GPT-4, Google’s Gemini, or local Ollama models into production systems, a new beacon has emerged: . spring ai in action pdf github

"Spring AI in Action" is more than just a book; it's a comprehensive learning ecosystem. By combining Craig Walls' clear writing style, the official Spring AI framework, the book's companion repository, and a rich set of community examples, Java developers have a well-defined path to becoming proficient in Generative AI. The team decided to use the following technology

public record OrderDetails(String item, int quantity, String urgency) {} public OrderDetails parseOrder(String unstructuredText) var converter = new BeanOutputConverter<>(OrderDetails.class); String promptMessage = """ Extract the order information from this text: input format """; PromptTemplate template = new PromptTemplate(promptMessage); Prompt prompt = template.create(Map.of( "input", unstructuredText, "format", converter.getFormat() )); String response = chatModel.call(prompt).getResult().getOutput().getContent(); return converter.convert(response); Use code with caution. 2. Retrieval-Augmented Generation (RAG)

Written by renowned Spring expert Craig Walls, "Spring AI in Action" focuses on practical, real-world application of generative AI within Spring Boot applications. As of 2026, it is considered the go-to resource for developers looking to move beyond simple API calls and build sophisticated AI systems. Setting up Spring AI with Spring Boot 3.x+ Integrating with OpenAI, Ollama, and local models. Building RAG applications to use your own data.

, focuses on integrating generative AI capabilities directly into Spring Boot applications. A standout feature covered in the book is Retrieval-Augmented Generation (RAG) The intersection of enterprise Java (Spring Boot) and

The true value of any technical book lies in its code. Craig Walls provides a comprehensive GitHub repository for the book, designed to be hands-on and practical. You can find the code here:

As the world continues to evolve, artificial intelligence (AI) and machine learning (ML) are becoming increasingly important in various industries. One of the most popular frameworks for building AI-powered applications is Spring, a comprehensive platform for building enterprise-level applications. In this story, we'll explore how a team of developers used Spring AI to build a smart chatbot that can understand and respond to user queries.
