Spring AI with Java: Build AI-Powered Applications (2026)

Spring AI with Java: Build AI-Powered Applications (2026) is a comprehensive, hands-on course for Java and Spring Boot developers who want to build modern AI-powered applications using Spring AI 2.0 and Spring Boot 4.x.

Rather than learning isolated examples, you’ll build a complete AI Travel Assistant from scratch and progressively enhance it throughout the course. Starting with a simple AI chatbot, you’ll transform it into a production-style AI application capable of maintaining conversations, invoking Java tools, retrieving knowledge from your own documents, understanding and generating images, processing voice interactions, and delivering a modern streaming chat experience.

Every concept is taught through practical coding exercises, giving you experience with real-world AI application development using Spring AI.

Includes free 90-day access to IntelliJ IDEA Ultimate for a professional development experience.

Includes professionally prepared subtitles in Spanish, Portuguese (Brazil), Japanese, and Chinese.

What you’ll build

• Spring AI Fundamentals: Configure Spring AI 2.0, build AI-powered REST APIs, and understand the complete request lifecycle.
• Prompt Engineering: Design effective prompts, build reusable prompt templates, generate structured responses, and implement prompt chaining.
• Conversation Memory: Build multi-turn conversational AI using ChatMemory, Conversation IDs, persistent JDBC-backed memory, and production memory strategies.
• AI Tool Calling: Enable AI to invoke Java methods, call REST APIs, query databases, return structured results, and chain multiple tools together.
• Retrieval-Augmented Generation (RAG): Build a complete RAG pipeline with PostgreSQL, pgvector, embeddings, multi-document retrieval, and custom Spring AI Advisors.
• Multimodal AI: Build applications that understand images and generate AI images using OpenAI and Stability AI.
• Audio AI: Implement Speech-to-Text, Text-to-Speech, voice-enabled chat, and complete voice AI workflows using Spring AI.
• Modern AI User Experience: Build browser-based chat applications with streaming responses, voice interactions, and a ChatGPT-style user experience.

By the end of this course, you’ll understand not only how to use Spring AI, but also how to build practical AI-powered applications with modern Java and Spring Boot.

Whether you’re building AI assistants, enterprise chatbots, document-aware applications, or intelligent business systems, this course provides the practical skills and real-world examples needed to confidently integrate AI into your Java and Spring Boot applications.
