Beans, Configuration & Lifecycle
"Bean" gets thrown around from your first day with Spring. This module is precisely what one is, how it's born, and how it dies.
Learning objectives
- Beginner: Recognize that "bean" just means "an object the container manages," not special new syntax.
- Intermediate: Choose correctly between @Component-style and @Bean-method declaration depending on whether you own the class being registered.
- Advanced: Predict and control lifecycle ordering issues (e.g. a bean depending on another bean that isn't ready yet) using @PostConstruct and lifecycle callbacks.
