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!
