Bootiful Spring Boot 3
summary
Spring Boot 3.1 targets Java 17, adds GraalVM-native images support via a Spring AOT engine (native builds take minutes but produce tiny runtimes — demo PID shows ~106 MB RSS), integrates Testcontainers service connections for local DBs, exposes RFC 7807 ProblemDetail error responses, unifies metrics and tracing with an Observation API on Micrometer, and provides declarative HTTP interfaces plus RSocket and GraphQL (with batch mapping to avoid N+1). Demos build a service, a client, and a GraphQL edge that works end-to-end.
