Answer
Only public methods are proxied by Spring AOP by default.
Spring AOP creates proxies to apply aspects like transaction management or logging. These proxies only intercept calls to public methods by default. If you have a method with package-private or private visibility, it won't be intercepted, and the aspect won't be applied. Therefore, it's crucial to ensure methods that require AOP are public, or use AspectJ for more flexibility. This concept is key when designing classes that rely on AOP features.
