Two start phases

[josep]

I've singleton beans that start some subsystems and they implement a mechanism of listening, so they need to start the subsystem after everything is configured (the listener-beans were added).

The listener-beans were added on their afterPropertiesSet method and I use the ApplicationEvent to start the subsystem. But this is not the rigth way in the case one subsystem depends on another because there is no order.

I could implement a BeanFactoryPostProcessor and examine the dependencies... but it's possible to do it in another generic way?

Thanks

what about using a depends-on attribute on the 'dependant-on-the-other' singleton. This will enforce proper order of initialization.
Hope this helps.
