Spring Framework FAQ: Top Questions

Spring provides various scopes to manage the lifecycle and visibility of beans in different contexts.

📘 Common Bean Scopes:

• singleton (default): one shared instance.
• prototype: new instance every time requested.
• request: per HTTP request (web only).
• session: per HTTP session (web only).

📥 Example:

@Scope("prototype")
@Component
public class MyPrototypeBean {
}

🏆 Expected Output:

Each request to container returns a new instance.

🛠️ Use Cases:

• Singletons for shared resources like services.
• Prototype for stateful or short-lived objects.
