Spring AI : My Multi-Provider AI Chat Bot

Spring AI : Multi-Provider AI Chat Bot



Overview

I recently published a small hands-on project to explore how to build AI capabilities in Java using Spring Boot and Spring AI.

I’ve kept the repository README detailed so anyone can run and test the APIs quickly.

If you’re learning Spring AI and want a compact reference project, feel free to explore, fork, or share feedback.

Why Spring AI?

Most AI examples today are Python-first, which makes sense from a research perspective. But in many enterprise environments, core systems are still Java-based.

Spring AI brings AI integration into the familiar Spring ecosystem. That means:

  • Dependency injection and clean configuration

  • Provider abstraction (switch models without rewriting business logic)

  • Consistent patterns alongside existing REST APIs

  • Easier integration into existing enterprise applications

For teams already building with Spring Boot, this makes AI features feel like an extension of the platform rather than a separate experimental stack.

What the Project Covers

This project focuses on a practical backend setup with:

  •   Chat APIs
  •   Conversation APIs
  •   Streaming responses (SSE)
  •   Prompt-based analysis endpoints (code + ticket analysis)
  •   Multi-provider AI support using header/config-based selection


Supported Models

  •   OpenAI
  •   Gemini
  •   Ollama (locally setup)
  •   Groq
  •   Cohere
  •   Mistral
The various providers were chosen to demonstrate flexibility and to expose readers to different ecosystems

What I Wanted to Explore

With this project, I focused on:

  • Clean abstraction of multiple AI providers

  • Model selection without changing business logic

  • Designing APIs that can support real workflows

  • Handling streaming responses properly in a Spring Boot setup
