Hello, dear visitor! I think I have an idea of what you want…

You want to learn how to create a complete Spring web application with oauth support, security, file upload and distributed sessions.

You want to master the principles of REST and develop a clean API with top-notch exception handling and following the best practices.

You also want to deploy it in the cloud and for it to be fully tested with both unit and end-to-end tests.

What a coincidence! I just wrote the book you are looking for!

If you want to have a look at what you will be building, its source code is available on github and it is deployed on heroku
