Bootiful Spring Boot: A DOGumentary
summary
Live demos claim practical migration paths: a adoption service for dogs is built end to end using Spring Boot with Java, Spring Data JDBC and HTTP clients, modularized with Spring Modulith outbox to turn synchronous events into reliably replayable, eventually consistent async work; security shows passkeys, one‑time tokens and MFA; resiliency uses retry/backoff and concurrency limits; a GraalVM native image with music plugin is attempted and produces a working native binary but requires manual runtime hints and minor fixes.
