Deep Dive : Bootiful Spring Boot 3.x
summary
Claims that Spring Boot 3.x + Java 21 make modern Java the integration and AI platform get demonstrated end-to-end: a modular dog‑adoption service using Spring Boot 3.x, Spring Data JDBC + PostgreSQL+PGVector, Spring AI (OpenAI embeddings) and Spring Modulith; events persist to an event_publication table for guaranteed delivery; a retrieval‑augmented assistant indexes ~18 dog records into the vector store; virtual threads roughly double throughput (≈1.7 → 3.2 req/s, total run 22s → 12s); GraalVM native image boots in ~0.1s at ~121MB. Some model hiccups occur, but the pipeline works.
