Spring Boot - specify concrete class in configuration properties.

Say I have a class


and I want to configure it with a bunch of concrete classes that implement ItemInterface...

Is it possible to specify the class of each item in application.yaml?

Something like



I should say, this is not something I can handle with profiles.
Ultimately this list will contain a different set of concrete classes per product deployment, so I would want to externalise it.

Did you resolve it with this?

Kinda sounds like you're trying to solve a programming problem with a build management tool.

Alternatively could you inject the right kind of "items" into your class based on some kind of configuration like an environment variable?

I did it by loading the config via ImportResource, using an xml bean definition (which lets you choose the concrete classes)
