Spring Framework FAQ: Top Questions

Spring supports externalized configuration using properties and YAML files. You can inject values using @Value or bind them to POJOs using @ConfigurationProperties.

📘 Features:

• Support for application.properties and application.yml.
• Profile-specific configs like application-dev.yml.

📥 Example:

@Value("${app.name}")
private String appName;

@ConfigurationProperties(prefix = "app")
public class AppConfig {
  private String name;
}

🏆 Expected Output:

Config values are injected and available in code.

🛠️ Use Cases:

• Manage environment-specific settings.
• Decouple code from configuration values.
