Bootiful Spring Boot: A DOGumentary
summary
Builds a dog-adoption service called Pooch Palace backed by Postgres and a Postgres vector store, embeds shelter records (Prancer id 45) and wires a Spring AI chat client for RAG so the assistant answers shelter-specific questions. Uses start.spring.io scaffolding, targets Java 25, enables virtual threads for scalability, and produces a GraalVM native image that boots in ~0.2s and uses ~157 MB RSS; demonstrates it works end-to-end.
