A way to accomplish @ConditionalOnANYClass?

Question

I am using Spring Boot autoconfiguration to load a bean in the context in case there is at least one of 3 beans present.

I need something like:

@Bean
@ConditionalOnANYClass({ CreateHandler.class, UpdateHandler.class, DeleteHandler.class})

Any smart solution or out-of-the-box annotation for the logical OR?

You can use AnyNestedCondition with one nested condition per class that you want to match.

Do I need o define a class explictly? Is there any closer way to provide it inline a la `@AnyNestedCondition({@ConditionalOnClass(A.class), @ConditionalOnClass(B.class)})` ? – Whimusical Jul 05 '17 at 22:12
