Using Hugging Face Models With Spring AI and Ollama

Date: 2025-02-20

This article demonstrates integrating Hugging Face LLMs into Java applications using Spring AI and Ollama. Ollama runs LLMs locally, simplifying deployment. Testcontainers facilitates testing with Dockerized Ollama. The example shows creating Spring Boot services for chat completion (using the Mistral model) and embedding generation (using all-MiniLM-L6-v2). REST controllers provide API endpoints for accessing these functionalities. Error handling is discussed, showing how to manage null responses. This approach enables efficient integration of advanced AI capabilities into Java projects.
