Spring: your next Java micro-framework
summary
Spring Boot 2.3 application using WebFlux and R2DBC with Postgres demonstrates microframework-style simplicity: full app boots in about starts in ~1.5s on the demo machine, and with spring-boot-devtools changes trigger a Spring restart and live reload in about restart on change ~0.5s. Code shows manual wiring via functional bean registration and a single-file routing table (functional routing), optional manual auto-configuration, and pointers to spring-graal-native and experimental spring-fu for native images. Everything runs in the demo.
