📌 Notes:

• This script is a mock simulation — the HAS_ flags represent whether a given cache provider is available in your classpath or config.
• To make this production-ready:
• Implement checks against your Java classpath, dependency list, or Spring Boot logs.
• Or write this logic directly in Java using Spring Boot’s ApplicationContext for real-time detection.
