You can advise an example of an application that you can take as a basis for your own (there are such examples on the githaba, but something I did not find). Where competently described work with the database, with the spring itself, and so on.

    What do not you like examples on the site spring Spring Tutorials ?

    I would advise you to take examples from the book "Spring 4 for Professionals" by the authors Chris Shefer, Clarence Ho, Rob Harrop.

    I studied it myself.

    Everything that you have listed is in this book and is described quite well. There is also about Spring itself and about working with the database.
