Bootiful Spring Boot 3.3
summary
Shows a concrete demo: a Spring Boot 3.x app (Spring Framework 6+) using Java 21, Docker Compose Postgres schema, Java records and pattern‑matching, and the Spring AI OpenAI starter to generate stories. It compiles to a GraalVM native image (102 MB), runs in ~0.1s and uses ~127 MB RSS. Virtual threads (Project Loom) remove blocking thread waits so 1,000 logical threads don’t tie up OS threads. Highlights Java 21, GraalVM native image, Spring AI, virtual threads.
