Create Custom ConfigFactory AEM

CustomConfigFactory.java

Here is how you can use configuration factory,


public interface MyCustomService{


}


--------------------------------------------



@Component (ConfigurationFactory=true, metatype = true, policy=ConfigurationPolicy.REQUIRE)

@Service(value = MyCustomService.class)

//This can be anything as explained above

@Properties({

    @Property(name=SOMETHING, unbounded=PropertyUnbounded.ARRAY),

    @Property(name=SOMETHING, unbounded=PropertyUnbounded.ARRAY),

    @Property(name="key",value="Something random")

})


public class MyCustomServiceFactory implements MyCustomService {


}


-----------------------------------------------------


public interface MyCustomServiceFacade {

  public MyCustomService getMyCustomService (String key);

}


-----------------------------------------------------


@Component

@Service

@References({

  @Reference (cardinality=ReferenceCardinality.OPTIONAL_MULTIPLE, policy=ReferencePolicy.DYNAMIC, referenceInterface = MyCustomService.class, name="MyCustomService")

})

public class MyCustomServiceFacadeImpl implements MyCustomServiceFacade {


private static String KEY="key";


private final Map<String, MyCustomService > myCustomServices = new HashMap<String, MyCustomService>();

private ComponentContext;


// works only for exact matches

public MyCustomService get MyCustomService(String key) {

  return myCustomServices.get (key);

}


protected void bindMyCustomService(ServiceReference ref) {

  synchronized (this. myCustomServices) {

    String customKey = ref.getProperty(KEY);

    MyCustomServices operation = this.componentContext.locateService("MyCustomService",ref);

//Or you can use

//MyCustomServices operation = ref.getProperty("service.pid");

    if (operation != null) {

      myCustomServices.put(customKey,ref);

    }

  }

}


protected void unbindMyCustomService(ServiceReference ref) {

  synchronized (this.myCustomServices) {

   String customKey = ref.getProperty(KEY);

    myCustomServices.remove(customKey);

  }

}


@Activate

protected void activate (ComponentContext ctx) {

  this.componentContext = ctx;

}


}
