Access to service properties in service consumer ( iPOJO )

In iPOJO, is there any way to read service properties (e.g. getProperty(key) ) in service consumer? The publisher is pretty straight forward but, in consumer seems I can only use filter.

Thanks

Solution

  • You have to use callbacks to retrieve service properties:

    @Bind
public void bindService(HelloService hello, Dictionary<String, Object> properties) {
      // ...
}

    or 

    @Bind
public void bindService(HelloService hello, Map<String, Object> properties) {
  // ...
}

    You can even retrieve the OSGi service registration:

    @Bind
public void bindService(HelloService hello, ServiceReference<HelloService> reference) {
  // ...
}
