How spring boot is working behind , Bean Life cycle method

Question

Accepted Answer

Spring Boot uses Bean Life cycle methods to manage the creation and destruction of beans in the application context.

Spring container instantiates the bean by calling the default constructor or a static factory method.
Spring sets the bean properties and dependencies using setters or constructor injection.
If the bean implements InitializingBean interface, the afterPropertiesSet() method is called.
If the bean has init-method specified in the configuration, that method is called.
Bean is now ready to be used by the application.
When the application context is closed, if the bean implements DisposableBean interface, the destroy() method is called.
If the bean has destroy-method specified in the configuration, that method is called.

Accepted Answer

Bean life cycle is managed by the spring container. When we run the program then, first of all, the spring container gets started. After that, the container creates the instance of a bean as per the request, and then dependencies are injected. And finally, the bean is destroyed when the spring container is closed.
