Annotation based injection into non public base classes does not work [SPR-7900] #12555
Description
Andreas Benneke opened SPR-7900 and commented
Annotation driven injection on public methods specified in a non-public base classes does not work, because Java generates bridge methods for the subclass which are not ignored by Spring (as they should IMHO).
Example:
/* not public! */ class Base {
@Resource
public void setResource(Injectable injectable) {
...
}
}
@Component
public class Target extends Base {
}
Same applies to @Autowired.
The attached maven project demonstrates this.
Workarounds: Use field injection, re-declare the method(s) in the subclass or make the base class public.
Affects: 3.0.5
