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) {
          ...
      }
   }
