Spring / Spring7 basics Interview questions
What is GraalVM native image support in Spring Framework 7?
GraalVM native image support lets a Spring Framework 7 application be compiled ahead of time into a standalone native executable, rather than running as bytecode inside a JVM. The result starts in milliseconds and uses a fraction of the memory of a regular JVM process, which is valuable for serverless functions and container-dense deployments.
./mvnw -Pnative native:compile
Because native images can't perform arbitrary reflection or dynamic class loading at runtime, Spring relies on its AOT processing step to precompute everything the native compiler needs to know up front - which beans exist, which proxies to generate, and which classes need reflective access - and feeds that information to the GraalVM compiler during the build.
What is the main runtime benefit of a GraalVM native image over a regular JVM process?
Why can't native images rely on ordinary runtime reflection the way a normal JVM app does?
