Ahead Of Time and Native in Spring Boot 3.0

on YouTube ↗44m

" summary

Spring AOT compiles Spring Boot 3 apps ahead-of-time into GraalVM native-image binaries by generating AOT sources at build time, invoking a build plugin, and emitting GraalVM reachability config. The demo builds a CLI native binary that runs with startup in megabytes and milliseconds of memory and latency savings but takes about 90 seconds to compile locally until CI/cloud builds are used. Missing reflection or resources get fixed with the new runtime hints API or generated code; generated Java is viewable in the IDE and tests/agent validate the hints.
