title: A way to accomplish @ConditionalOn*ANY*Class?
body: <p>I am using Spring Boot autoconfiguration to load a bean in the context in case there is at least one of 3 beans present.</p>
  
  <p>I need something like:  </p>
  
  <pre><code>@Bean
  @ConditionalOnANYClass({ CreateHandler.class, UpdateHandler.class, DeleteHandler.class})
  </code></pre>
  
  <p>Any smart solution or out-of-the-box annotation for the logical OR?</p>
