Spring Framework FAQ: Top Questions

Spring supports several bean scopes to define the lifecycle and visibility of a bean in the application context.

📘 Common Scopes:

• singleton – Default. Single instance per Spring container.
• prototype – New instance every time it's requested.
• request – Per HTTP request (web apps only).
• session – Per HTTP session (web apps only).
• application – Scoped to ServletContext.

📥 Example:

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

🏆 Expected Output:

Each call to getBean() returns a new instance of MyBean.

🛠️ Use Cases:

• Use prototype for stateful beans.
• Use request/session/application for web application state.
