Langchain4j Tool Function Calling Patterns
giuseppe-trisciuoglio/developer-kitDevelopers can turn Java methods into tools that AI agents can call. The LangChain4j library uses the @Tool annotation to mark methods as callable functions. This helps agents do tasks like fetching weather data, running calculations, or querying databases.
With AiServices, you register these tools with a language model. The model then knows when and how to use them. You can also add error handlers to keep responses safe and clear. This pattern makes AI agents more useful and reliable.
