Mastering Spring Framework Fundamentals - Spring-managed Bean Lifecycle Callback Methods

The video tutorial explains the concept of callbacks in the Spring framework, focusing on the lifecycle of beans. It covers the initialization and destruction phases, detailing methods like 'after properties set' and 'destroy'. The tutorial also discusses the application context lifecycle, emphasizing the importance of explicitly closing the context to ensure proper resource management. Key interfaces like InitializingBean and DisposableBean are highlighted, showing how they allow developers to hook into the bean lifecycle for initialization and cleanup tasks.
