Bootiful Spring Boot 4
summary
Spring Boot 4 demo builds an adoption service using Maven, Java 25 (showing Java scripting), Spring Modulith with an event_publication outbox table for eventual consistency, Spring Data AOT-generated repositories, declarative HTTP clients, retry with maxAttempts=4 and a concurrency limit of 10, WebAuthn passkeys and one‑time tokens, and GraalVM native image that boots in 0.13s native startup and uses 124MB memory versus ~856MB for a Chrome JS client — all features work end-to-end in the demo.
