Spring AI + RAG: Build Production-Grade AI with Your Data

Most RAG courses stop at loading a few documents and asking questions.

This course goes further.

Spring AI + RAG: Build Production-Grade AI with Your Data teaches you how to design, build, and operate a real Retrieval-Augmented Generation (RAG) system the way backend engineers build serious systems — with clear boundaries, explicit pipelines, and production-minded decisions.

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.

This is not a prompt-engineering or chatbot tutorial.
It is a backend-first system design course focused on correctness, reliability, and long-term maintainability.

You will build a complete Internal Knowledge Assistant for a fictional company, using:

• Spring Boot

• Spring AI

• PostgreSQL

• Redis / vector stores

The same codebase evolves throughout the course, exactly like a real backend system.

What Makes This Course Different

• RAG is treated as a system, not a prompt trick

• Ingestion, chunking, retrieval, and prompting are separate, testable pipelines

• Metadata is a first-class concern, not an afterthought

• Knowledge can be added, updated, and deleted safely

• Everything is implemented using Spring AI abstractions, not custom hacks

• No Python, no LangChain, no demo-only shortcuts

By the end, you will not just “use Spring AI” — you will understand how to own and evolve an AI system in production.

What You Will Learn

• How to design ingestion pipelines for PDFs, Markdown, and databases

• Why chunking strategies directly affect retrieval quality

• How embeddings and vector stores fit into backend architecture

• How to build metadata-aware retrieval pipelines

• How to control LLM behavior with explicit prompt orchestration

• How to manage knowledge lifecycle: add, update, delete

• How to build RAG systems that remain correct as data changes

Course Modules Overview

This course is organized as a progressive backend system build, where each module introduces exactly one new system concern.

• Module 1 — Setup & Spring AI Baseline
  Spring Boot + Spring AI setup and a minimal chat endpoint to establish the foundation.

• Module 2 — RAG Readiness
  Use-case framing, data sources, and infrastructure setup (PostgreSQL, Redis).

• Module 3 — Ingestion Pipelines
  Designing repeatable ingestion for PDFs, wiki content, and database records.

• Module 4 — Chunking Strategies
  Source-specific chunking approaches and a unified chunking pipeline.

• Module 5 — Embeddings & Vector Storage
  Generating embeddings and persisting them with metadata in a vector store.

• Module 6 — Retrieval Pipelines
  Metadata-aware similarity search and clean retrieval integration into chat.

• Module 7 — Prompt Orchestration & Reliability
  Grounded prompts, explicit behavior control, and citation-based, source-attributed answers.

• Module 8 — Knowledge Lifecycle
  Safe add, update, and delete workflows to keep the system correct over time.

Who This Course Is For

• Java and Spring Boot developers

• Backend engineers integrating AI into real systems

• Developers who already understand REST APIs, databases, and Spring fundamentals

• Engineers who want to move beyond demo-level RAG implementations

Who This Course Is NOT For

• Absolute beginners to Java or Spring

• No-code or prompt-only AI learners

• Frontend-focused developers looking for chatbot-only examples

• Learners expecting quick "load a PDF and chat" style examples

Outcome

After completing this course, you will be able to:

• Design RAG systems confidently

• Build production-grade AI pipelines using Spring AI

• Reason about correctness, reliability, and system boundaries

• Apply the same architecture to other real-world use-cases

This course gives you the mental model and engineering discipline needed to build AI systems that last.
