Spring AI’s ChatMemory abstraction can handle this automatically. For a production system, combine short‑term Redis (TTL 5 min) with a longer‑term persistent store.

public class OllamacExample public static void main(String[] args) OllamacModel model = OllamacModel.load("path/to/model.zip"); String input = "Hello, world!"; String output = model.generateText(input, 100); System.out.println(output);

Which one to choose? If you just need the basics, Olljava is the simplest. If you plan to experiment with advanced features (branching models, generating UML diagrams from code, etc.), Jllama offers more power.

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Connection refused | Ollama server is not running. | Ensure ollama serve is running in the background or Docker container is active. | | Model 'xyz' not found | The specified model hasn't been pulled. | Run ollama pull <model-name> on the command line. | | Slow response times | Model is too large for available RAM/VRAM. | Use a smaller quantized model (e.g., qwen2.5:7b-q4_K_M ). | | Garbled or nonsensical output | Incorrect model parameters or prompt format. | Simplify your prompt. Adjust temperature to be lower (e.g., 0.2). |

Spring AI is the go-to framework for Spring developers. It provides a standardized abstraction, allowing you to switch between different LLM providers like Ollama, OpenAI, or Anthropic with minimal code changes.

: You can easily swap between different models (e.g., Mistral for speed, DeepSeek for coding) without changing your entire codebase.

A 50‑person fintech team saved over $200,000 per year by switching from OpenAI’s API to Ollama for code completion, test generation, and refactoring tasks. They saw average latency drop from 820 ms to 110 ms, and not a single line of proprietary code left their network.
