Since the introduction of annotations in Java 5, numerous frameworks have made good use of them in a runtime context, but less has been done to take advantage of their compile-time capabilities. Writing annotation processors is straightforward and can turn what would be runtime problems into compile-time warnings or errors. This presentation discusses ways annotation processors can improve the development process and shows a complete example of a processor that provides compile-time verification of certain JPA invariants. Attendees will discover that writing annotation processors is not a black art but something that is safe to "try at home."
