Question - What is the Bean life cycle in Spring Bean Factory Container?
Answer -
Bean life cycle in Spring Bean Factory Container is as follows:
- The Spring container instantiates the bean from the bean’s definition in the XML file.
- Spring populates all of the properties using the dependency injection, as specified in the bean definition.
- The factory calls setBeanName() by passing the bean’s ID, if the bean implements the BeanNameAware interface.
- The factory calls setBeanFactory() by passing an instance of itself, if the bean implements the BeanFactoryAware interface.
- preProcessBeforeInitialization() methods are called if there are any BeanPostProcessors associated with the bean.
- If an init-method is specified for the bean, then it will be called.
- Finally, postProcessAfterInitialization() methods will be called if there are any BeanPostProcessors associated with the bean.
