Answer from AI
The lifecycle of a bean in the Spring Framework includes several key stages:
- Creation of the instance — Spring creates the bean object, usually through the constructor.
- Dependency injection — automatic or manual injection of dependencies into fields or setters occurs.
- Callback processing — if the bean implements interfaces like
BeanNameAware,BeanFactoryAware, etc., the corresponding methods are called to pass the context. - Initialization — a method annotated with
@PostConstructor specified ininit-methodis called. - Bean usage — the bean is ready for use and is used in the application.
- Destruction — when the work is finished, methods annotated with
@PreDestroyor specified indestroy-methodare called.
This process provides flexible management of object lifecycle in the application.
