Spring Framework FAQ: Top Questions

BeanFactory and ApplicationContext are both Spring IoC containers but differ in features and usage.

📘 Key Differences:

• BeanFactory: Basic container, lazy initialization, no support for AOP, internationalization, or events.
• ApplicationContext: Full-featured container with bean post-processing, event propagation, and more.

📥 Example:

ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");

🏆 Expected Output:

Fully initialized context with loaded beans and additional services.

🛠️ Use Cases:

• Use ApplicationContext for modern Spring applications.
• BeanFactory for lightweight or legacy scenarios.
