Boot yourself, Spring is coming
summary
A live walk‑through builds a Spring Boot starter that sends a raven when an app starts, showing code, spring.factories wiring and auto‑configuration rules, and how properties and configuration‑properties metadata produce IDE autocompletion. The demo counts 436 beans loaded into a minimal app and explains why so many appear, how Condition annotations are evaluated (and when their checks run multiple times), and how early extension points (Environment/Bootstrap processors and ApplicationListeners) can set active profiles before the context refresh.
