Service Factory implementation using declarative services in OSGi

I am registering an OSGi service using OSGi declarative service and setting

servicefactory="true"

as follows.

<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" name="test.Configuration">
  <implementation class="test.ConfigurationImpl"/>
  <service servicefactory="true">
     <provide interface="test.Configuration"/>
  </service>
</scr:component>

I am trying to use the service multiple times from another bundle. But, it returns me the same instance of the service.

What could possibly go wrong here ??

The servicefactory flag means that each consumer bundle gets a separate instance. So if you consume the service from 2 bundles then you will get 2 instances. You do not get multiple instances per consumer.

If you want programmatic control from the consumer over the number of instances then you need to use the ComponentFactory approach.
