Describe AOT processing in Spring Framework 7?

Ahead-of-Time (AOT) processing shifts work that Spring normally does at runtime - resolving conditions, computing bean definitions, generating proxy classes - to build time instead. During the build, Spring analyzes the application context and generates Java source and bytecode that reproduce that same context far faster, without needing reflection-heavy startup logic.

mvn -Pnative spring-boot:build-image

The immediate payoff is dramatically faster startup and lower memory use, since the container doesn't have to reason things out dynamically every time the JVM boots. AOT processing is also the foundation that makes GraalVM native image compilation possible, because native images can't rely on the reflection and dynamic class loading a normal JVM startup would use.
