Annotation Type EachBean

@Documented
 @Retention(value=RUNTIME)
 @Target(value={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) {
          ...
      }
   }
