Annotation Interface EachBean

@Documented
@Retention(RUNTIME)
@Target({METHOD,TYPE})
@Singleton
public @interface EachBean

This annotation allows driving the production of Bean definitions from presence of other bean definitions. Typically used in conjunction with EachProperty

For example:

  @EachProperty("foo.bar")
   public class ExampleConfiguration {
   }
 

In the above example a new ExampleConfiguration bean will be created for each item under the foo.bar key in application configuration

One can then drive the configuration of other beans with the same annotation:

  @EachBean(ExampleConfiguration)
  @Singleton
   public class ExampleBean {
      ExampleBean(ExampleConfiguration config) {
          ...
      }
   }
 

EachBean requires that the parent bean has a Named qualifier, since the qualifier is inherited by each bean created by EachBean.
