We have a mix of OSGi DS services (Declarative Services components) and
Spring beans and services. Is it possible to use a Spring bean as a
property of a DS service, i.e. inject the Spring bean into the DS
service? Would it help if the Spring bean were declared as a service
using Spring DM?

Hi Craig,
using Spring DM it's easy to inject a bean into a service implementation
and vice versa.

I don't think that its possible to inject a Spring bean into a service
component created with Equinox DS as the lifecycle of the object is not
known to Spring.

What you of course can do is publish an OSGi service using Equinox DS
and consume it with Spring DM or vice versa.

Regards,
Stefan.

Thanks for replying Stefan, this looks promising.

Regarding exposing a Spring bean as a DM service and consuming it in a DS component service, do you have an example?

Does the DS XML declaration reference the DM service by id or interface? Does the resolution of that dependency require the bundle declaring the Spring bean be started? If so, how should it be started?

I like DS in that the first consumer of the service starts the service bundle automagically while I had problems with DM services not being available if the declaring bundle is not somehow started.

Any help greatly appreciated!

A long time ago I have created such a example:

maybe it can be helpful.
