They should combine properly , but that code is tricky and I'm sure there may be bugs. The reason it's suppsoed to work is that there's a chain of beans involved and Spring is *supposed* to apply a parent bean's properties before the child's properties. That should result in the static setter being called after the setter that injects the function lookup, so the static setter "replaces" the dynamic function with a constant/static function.

I do it in some cases but I haven't exhaustively tested or tried to combine specific metadata signals with static signals for the same setting. I just tested the basic behavior to see if it matched what Spring claims it does.

Maybe you're expecting the opposite, and the opposite is not the intended behavior. The static configuration SHOULD override the metadata. That is what I would expect as a deployer.
 I define properly as "the configuration should override the metadata".
