@PostConstruct and @PreDestroy in Spring

1. 1Add the @PostConstruct annotation to a method to execute it after dependency injection and constructor execution
2. 2Use the @PreDestroy annotation to execute a method before the bean is destroyed
3. 3Configure the bean lifecycle using these annotations to improve application performance and resource management
4. 4Test the application to ensure the annotated methods are executed correctly
5. 5Apply these annotations to existing beans to optimize their lifecycle management

Backend developers and engineers working with Spring can benefit from understanding these annotations to optimize their application's startup and shutdown processes
