This 40+ pages manuscript shouldn’t be considered as a book, but it’s author insists to call it so.
There’s a certain lack of materials covering building a robust Rest API with Spring. Most of the manuals I’ve seen operate with JAX-RS, which Spring MVC doesn’t conform to.
There’s also a great talk by the creator of Apache Shiro which I would recommend to anyone striving to do a scalable web service regardless of particular language/technology you use.
I’ve been doing web services for a long time using different technologies (node, Clojure to name a few). I always try to do it as efficient as I can. This time I had an issue while integrating security layer into Spring MVC.
To make a long story short, this book is a waste of time:
It’s huge, some parts of it are repeating. I have no idea why the author has intended to do so much copy-paste
Some postulates are not true. Though Spring security 3.2 had a java config this book says that it hadn’t.
It doesn’t cover features of Spring 4 at all. The author has forgotten to update his book. Albeit he aggressively promotes it.
For a free ebook it’s not awful, but i would definitely recommend you to find some other book.
