Spring Framework FAQ: Top Questions

ApplicationContext is the central interface to the Spring IoC container. It provides configuration, bean management, event handling, internationalization, and access to application resources.

📘 Features Beyond BeanFactory:

• MessageSource for i18n support.
• ApplicationEventPublisher for event propagation.
• ResourceLoader for loading files.

📥 Example:

ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
MyService service = context.getBean(MyService.class);

🏆 Expected Output:

Beans are auto-wired and initialized; events and i18n messages available.

🛠️ Use Cases:

• Enterprise apps requiring resource and event management.
• Web apps with complex lifecycle and configuration needs.
