Unleash the power of your applications with Micronaut & GraalVM
summary
Micronaut 4 shows end-to-end compile‑time wiring: dependency injection, repository implementations and JSON serializers are generated ahead of time so there's no reflection, no classpath scanning, and compile errors catch typo bugs. Demo app uses Micronaut Data, Flyway and H2, runs integration tests in 300 ms test startup (including migrations) and produces a GraalVM Native Image that starts in ~32 ms with a ~12–18 MB footprint. Notes Java 17 baseline and automatic Test Resources/Testcontainers support.
