From Spring Native to Spring Boot 3

on YouTube ↗01h 01m

" summary

Official Spring Boot 3 replaces Spring Native and adds built-in GraalVM native-image support via the native build tools plugin and optional buildpacks; Java 17 and Jakarta are required. Applications compile to small executables (demo shows a 65 MB native binary) that start in tens of milliseconds (demo ~52 ms) and support running tests inside the native image. Ahead‑of‑time transforms generate plain Java bean code instead of reflection (AOT-generated bean code). Caveats: profiles are baked at build time, some libraries need JSON reachability hints, and observability via agents requires build-time config.
