What Is Spring?
summary
Spring is a modular framework plus an ecosystem of projects; Spring Boot manages versions via start.spring.io and spring-boot-starter-web, letting a generated app run a REST endpoint instantly. Demonstration shows JVM startup ~1.495 seconds at ~423 MB, and a Graal native build drops that to ~0.06 seconds and ~65 MB. Spring Data, Spring Security/Authorization Server, Micrometer, Spring Cloud (Gateway, Stream, Config, Task, Data Flow), Spring Batch and Project Reactor provide concrete solutions for persistence, metrics, messaging, batch jobs and reactive IO.
