Configuration class with Bean factory method on an interface generates wrong target with AOT

[MartinLei]

Spring-Boot version 3.2.4

The processAot task does not generate the right BeanDefinitions files, if a configuration class uses composition of beans trough interfaces.

See showcase project

@MartinLei thanks for the sample but the README instructs to list a file without additional information. The app starts fine so I am not really sure what you mean.

Thank @snicoll for your prompt feedback.
Please excuse my very short README.md. I added more details how to reproduce the problem for spring native builds.

I hope this makes it more clear :)

This is working fine with AOT on the JVM. It does fail on native with:
