1. Mastering Spring AI: Easily Add
LLM Smarts to Your Spring Boot
Applications
Introduction
The Rise of AI APIs
Over the past few years, AI has rapidly transitioned from research labs to
real-world applications. Thanks to AI APIs from providers like OpenAI, Google
Gemini, Anthropic Claude, and others, developers can now access powerful

2. large language models (LLMs) with just a few lines of code, making Spring
Boot AI integration increasingly practical.
The New Problem: Integration Complexity
However, with that ease comes a new kind of complexity:
​
​ Every provider has its SDKs
​
​ Different authentication flows
​
​ Inconsistent response formats
​
​ Manual code duplication for switching vendors
This makes supporting multiple providers, or switching between them, tedious
and error-prone, especially for those exploring Spring AI OpenAI integration.
Enter Spring AI: A Unified Abstraction
That’s where Spring AI comes in. Developed by the Spring team, this project
brings the Spring Boot developer experience to LLMs by offering:
​
​ A consistent programming model
​
​ Unified configuration patterns
​
​ Easy switching between providers like OpenAI and Gemini

3. What You'll Learn in This Blog
In this post, we’ll walk through a working Spring Boot POC that integrates both
OpenAI and Google Gemini. You’ll learn how to:
​
​ Use Spring AI’s ChatClient abstraction
​
​ Swap providers with just a parameter change
​
​ Avoid vendor lock-in from day one using Spring AI LLM practices
Whether you're exploring providers or aiming to build a flexible AI-powered
backend, this post is for you. If you're planning to apply LLMs in real-world
apps, consider AI and machine learning consulting to help architect scalable,
intelligent solutions tailored to your domain.

4. What is Spring AI?
Spring AI is a relatively new addition to the Spring ecosystem that brings AI
model integration, especially large language models (LLMs), into the familiar
Spring Boot world. Just like Spring abstracts database access, messaging,
and security, Spring AI does the same for AI and ML capabilities.
Instead of wrestling with REST APIs, raw payloads, and provider-specific
quirks, Spring AI provides clean, Spring-style abstractions for interacting with
models like GPT, Gemini, or Azure OpenAI.
Why Spring AI Matters?
At its core, Spring AI lets you:
​
​ Use a standardized interface (ChatClient) to interact with multiple
providers
​
​ Avoid boilerplate code
​
​ Easily switch between LLM providers (OpenAI, Gemini, Azure, etc.) with
minimal config changes using Spring AI Java LLM integration
techniques
This means you focus on business logic, not SDK wiring.

5. Core Features
Unified ChatClient Abstraction
Spring AI provides a common ChatClient API for sending prompts and
receiving responses, regardless of which model or provider is behind the
scenes.
chatClient.prompt("Your input").call().content();
This enables plug-and-play flexibility when changing backends and supports
the growing interest in how to integrate LLM in Spring Boot.
