Can you explain the stages of the object lifecycle within the Spring Framework?

The lifecycle of an object in the Spring Framework includes several stages managed by the Spring container:

1. Object creation (Bean instantiation) — Spring creates an instance of the bean class.
2. Property value setting (Dependency Injection) — the container injects dependencies specified in the configuration.
3. Callback methods invocation:
   • If the bean implements the BeanNameAware interface, the setBeanName() method is called.
   • If it implements BeanFactoryAware, setBeanFactory() is called.
   • If it implements ApplicationContextAware, setApplicationContext() is called.
4. Processing of @PostConstruct annotations or methods specified in init-method — bean initialization.
5. Using the bean in the application — the bean is ready for use.
6. Shutdown and destruction:
   • When the container shuts down, methods annotated with @PreDestroy or specified in destroy-method are called.

This lifecycle allows Spring to manage the creation, configuration, and destruction of objects, providing flexibility and control over component behavior.
