Bootiful Spring Boot 3.x
summary
Builds a real dog adoption service called Pooch Palace that wires Spring Boot 3.x with Java 21 + Spring Boot 3, uses Spring Modulith for a modular monolith, publishes adoption events to a durable event_publication table for guaranteed replay, and adds a Spring AI assistant backed by PGVector embeddings for retrieval‑augmented answers. Demonstrates async decoupling and shows virtual threads improving throughput (total run ~12s with virtual threads vs ~22s without) and GraalVM native image for sub‑second startup and much lower memory.
