Java: Inversion of Control (IoC)

The Spring container manages bean destruction by invoking lifecycle methods like @PreDestroy.

When a Spring container is closed, it calls the @PreDestroy annotated method on beans to allow them to release resources or perform cleanup operations. This is particularly useful for beans managing resources like database connections or file handlers. For example, a bean managing a connection pool might close all connections when the application shuts down, preventing resource leaks.
