Will keep on adding samples/examples as I come across...
If you are getting error & your Spring Boot application is not starting due to some missing class or class definition.
And you are sure that your POM file is correct & complete.
Then before trying other solutions, just try to delete all the files from .m2 folder on your machine & let all the required files be downloaded again.
Or directly use SpringBoot version - 2.0.4 or 1.4.2.RELEASE

I will be posting the working project taken from the above blog & below attached pdf. And I had to make a few changes in that to make it working & did some refactoring.
So will attach all the files here as .zip which you can use on your local.
I have added few of my comments in the attached file which may help you while practising. I have studied 5 chapters only from this book & added my comments & highlighted important words or lines there.

While developing any application, it is always good to handle the corner scenarios & handle the situations if something goes
out of the hand. In short it always good to handle the exceptions occuring in the application & try to wrap them under your
business specific exceptions which should be Runtime Exceptions & have meaningful messages to the client with relevant error codes.
For this you will be defining your own Business specific exceptions & use them while returning any exception.
