Intro to Spring in German

Finally there is a introduction for the Spring framework in German.
It is a nice read and it is written by Jürgen Höller, the Co-Lead of the Spring Framework.
IMO it is a bit centred on the rationale why to choose the spring framework. But since it is not well spread in Germany yet a focus on the rationale side comes quite handy.
I missed a bit the history of Spring and a more detailed example with some more code.
