Annotation Type RequiresBean

@Retention(RUNTIME) @Repeatable(Container.class) @Target({TYPE,METHOD,ANNOTATION_TYPE}) public @interface RequiresBean
Expresses a requirement for a bean to be wired/registered into the BeanScope. 


   @Factory
   public class MyAutoConfiguration {

     @Bean
     @RequiresBean(OtherService.class)
     public MyService myService() {
         ...
     }
   }

In the sample above the MyService bean will get wired only if a bean of type OtherService is already registered in the BeanScope.
