RESTful Web Services with Dropwizard` by Alexandros Dallas is a good guide to get started with dropwizard. 
The author covers most of the features of dropwizard which includes creating RESTful End points, Database access, Authentication, Creating views by means of developing a sample Phonebook application.
The book is not an exhaustive guide to dropwizard and may not match the documentation provided on the Dropwizard official site. But the approach of developing a sample application adding features in each chapter might appeal to some readers.
If you are kind of person who likes learning a framework by developing a sample application, then you can pick this book. Otherwise I would suggest the documentation would suffice.
What is the advante od Dropwizzard with comparison to Jackson etc. ?
Comparing Dropwizard to Jackson is like comparing apples to oranges. Both are built to serve totally different purposes. Jackson – JSON, XML processing and Dropwizard to rapid development of Java based RESTful services and web applications.
Dropwizard in turn uses Jackson for JSON processing.
