Spring AI Explained: Easy AI Integration for Java Developers

🚀 Getting Started with Spring AI: Adding AI to Your Java Apps

If you’ve been building with Spring Boot for a while, you know how great it is for developing robust Java applications. Now imagine adding AI-powered features — like chatbots, summarizers, or smart assistants — with just a few lines of code. That’s exactly what Spring AI makes possible.

In this post, I’ll walk you through:

• What Spring AI is all about
• How to set it up in a Spring Boot project
• A couple of real-world examples (chatbot + summarizer)

🔹 What is Spring AI?

Spring AI is a new project in the Spring ecosystem that helps developers easily connect their applications with Large Language Models (LLMs) like OpenAI’s GPT.

Instead of juggling raw API calls, you can use simple Spring abstractions to:

• Generate natural text
• Summarize documents
• Automate workflows
• Build intelligent microservices

🔹 Setting Up Spring AI

To get started, add the dependency in your Maven project:

<dependency>

    <groupId>org.springframework.ai</groupId>

    <artifactId>spring-ai-openai-spring-boot-starter</artifactId>

    <version>1.0.0-M1</version>

</dependency>

  

Then configure your API key in application.properties:

spring.ai.openai.api-key=${OPENAI_API_KEY}

spring.ai.openai.chat.options.model=gpt-3.5-turbo

  

🔹 Example: Calling AI from Spring Boot

import org.springframework.ai.chat.client.ChatClient;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.CommandLineRunner;

import org.springframework.stereotype.Component;

@Component

public class AiExample implements CommandLineRunner {

    @Autowired

    private ChatClient chatClient;

    @Override

    public void run(String... args) {

        String response = chatClient

                .prompt()

                .user("Write a haiku about Spring Boot and AI")

                .call()

                .content();

        System.out.println("AI Response: " + response);

    }

}

  

That’s it — just inject ChatClient and call the model like you would any other Spring bean.

🔹 Real-World Example #1: Customer Support Chatbot

Instead of hardcoding FAQ answers, you can let AI respond intelligently:

String response = chatClient

        .prompt()

        .user("How do I reset my account password?")

        .call()

        .content();

System.out.println("Bot: " + response);

  

This kind of setup is perfect for AI-driven chatbots that save time and improve the customer experience.

🔹 Real-World Example #2: Summarizing Documents

Spring AI can also summarize long text — think meeting notes, logs, or reports:

String documentText = """

Meeting covered Q3 growth, product roadmap, and hiring.

Decisions: Launch new feature in October, expand team in India.

""";

String summary = chatClient

        .prompt()

        .user("Summarize this in 2 bullet points:\n" + documentText)

        .call()

        .content();

System.out.println("Summary: " + summary);

  

Instead of reading through pages of text, you get short, clear takeaways in seconds.

🔹 Why This Matters

Spring AI lowers the barrier for Java developers to start experimenting with AI. You don’t need to switch languages or frameworks — you can stay in your Spring Boot comfort zone while adding cutting-edge features.

Some potential use cases include:

• 🤖 Smart chatbots
• 📄 Automatic document summarization
• 🔍 Semantic search across data
• 💻 AI-driven automation in microservices

🔹 Final Thoughts

I’m really excited about what Spring AI means for the Java community. It’s a chance to bring AI directly into enterprise applications without overcomplicating things.

If you’re already building with Spring Boot, give Spring AI a try — start small with a chatbot or summarizer and see where it takes you.
