Not fully convinced that DJ is the only best solution. Faced, Factory pattern can resolve the situation as well.

It looks like the DJ moves the code from Java file to xml file.

DI is basically a constructor injection?

Why not simply use a Factory pattern to eliminate instantiating the one class in another? How is Spring better than the that?
