Spring Framework FAQ: Top Questions

Inversion of Control is a principle where control of object creation and lifecycle is shifted from the application code to the Spring container. This is the core concept behind Spring's DI mechanism.

📘 Explanation:

• Objects are created, configured, and managed by Spring container.
• Developers define beans in XML or via annotations.

📥 Example:

@Component
public class ServiceA {
}

🏆 Expected Output:

Spring creates and manages ServiceA bean lifecycle automatically.

🛠️ Use Cases:

• Centralized configuration and control of components.
• Better abstraction of service creation and wiring.
