Answer
CGLIB proxies require non-final classes and methods.
CGLIB proxies subclass the target class to add proxy functionality, which means the class and methods cannot be final. This can be a limitation if your design requires final classes for reasons like security or immutability. For instance, if you need to proxy a method in a final class, CGLIB cannot be used, and alternative strategies like interface-based proxies must be considered.
