Class SpringAiLLMProvider

java.lang.Object
com.vaadin.flow.component.ai.provider.SpringAiLLMProvider
All Implemented Interfaces:
LLMProvider

public class SpringAiLLMProvider extends Object implements LLMProvider
Spring AI implementation of LLMProvider.

Supports both streaming and non-streaming Spring AI models. Tool calling is supported through Spring AI's Tool annotation.

Each provider instance maintains its own chat memory. To share conversation history across components, reuse the same provider instance.

Note: SpringAiLLMProvider is not serializable. If your application uses session persistence, you will need to create a new provider instance after session restore.
