Spring Bean Lifecycle & Spring Configuration Tutorial : Spring Framework & Spring Boot Annotation
Bean in Spring Framework, Bean in Spring, Configuration in Spring, Configuration in Spring Framework
The Spring Framework relies on objects called Beans which are managed by the IoC (Inversion of Control) Container. Understanding how a bean is created, configured, and destroyed—its lifecycle—is fundamental to writing effective and robust Spring applications.
@Configuration and @Bean define what a bean is, but the lifecycle governs when that bean is ready and how it cleans up its resources. Mastering the lifecycle callbacks (@PostConstruct and @PreDestroy) ensures your application starts and shuts down gracefully.
