Скачать или смотреть Spring Boot - Bean Lifecycle Interview Prep | BeanFactoryPostProcessor Vs BeanPostProcessor | #2

In this video, We will learn about the bean lifecycle and the importance of BeanFactoryPostProcessor and BeanPostProcessor.

In spring framework, the bean creation process goes through different phases. We spoke about the Spring Initializaiton and dependency injection already. But even before the spring bean initialization , We can implement a BeanFactoryPostProcessor to have a hold to the bean definition.

Using the BeanFactoryPostProcessor, We can alter the definition of the bean. For an example if we would like to change the scope of the bean.

In the other hand , Using the BeanPostProcessor, We can have a hold to the actual bean object after it got created and play with it. The BeanPostProcessor have two methods which executes before and after the lifecycle call back methods. i.e @PreDestory & @PostConstruct.
