Building AI Chatbot with Spring Boot, React and ChatGPT (Live Code)
summary
Live code builds a Spring Boot + React app that calls ChatGPT via Lang chain for J and uses Hilla to wire front end and back end, creates vector embeddings from a terms_of_service file stored in an in-memory retriever, streams tokens to the browser as streaming responses, and exposes limited functions (get booking details, cancel booking) as a cancel booking tool — the demo retrieves the correct cancellation rule and successfully executes cancellations against the demo backend.
