🌐 *Spring Boot @ConfigurationProperties | Awesome Property Validation Demo*

Want to take your Spring Boot configuration to the next level? In this demo, you’ll see how to use *@ConfigurationProperties* along with *property validation annotations* to enforce rules (like non-null, min/max values) in a clean, type-safe way.

This tutorial is perfect for beginners who want to make their configuration code more reliable, robust, and maintainable — no mess, just smart setup.

✨ *In this video, you’ll learn:*
✅ How to declare a *@ConfigurationProperties* class to bind application settings
✅ How to add *validation annotations* (e.g. `@NotNull`, `@Min`, `@Max`) to your configuration class fields
✅ What happens when invalid property values are provided, and how Spring Boot reports errors
✅ How to enable validation by adding `@Validated` and customizing error messages
✅ How to structure nested property classes and validation groups
✅ Best practices for managing and organizing configuration validation in real projects

By the end of this demo, you’ll be able to create configuration classes that *automatically enforce property correctness* — making your Spring Boot app more resilient and error-proof.
