How to Implement Pre‑warming in the Spring Ecosystem: Extension Points and Their Execution Order

Implementing pre‑warming in Spring involves using several extension points—SmartLifecycle, ApplicationListener for ContextRefreshedEvent, InitializingBean, @PostConstruct, ApplicationRunner, and CommandLineRunner—each with specific execution timing and ordering considerations to ensure cache loading occurs before the web server starts handling traffic.
