Jackson is a popular, high-performance JSON processor for Java. Jackson can support almost any JSON need that you might have, but that flexibility can make it complex to use. This book takes a problem and then shows, with lots of code and JSON examples, how to solve that problem using various Jackson features. Many of these problems were ones I encountered integrating JSON support with a \"legacy\" codebase, i.e., a codebase where I couldn't modify the code, using Data Binding, but I'll also cover some of the Streaming API that's used within custom serializers/deserializers. As a bonus, the Appendix contains a description of JSON tools that I've found useful along the way.

Topics Covered:

Configuring the ObjectMapper with pretty-printing, null-handling, and more
Integrating with legacy or third-party code using mix-ins
Ignoring properties and types and adjusting property auto-detection
Writing custom serializers and deserializers
Using @JsonCreator and value instantiators
Grouping customizations into Modules

Problems Welcome!

If you're using Jackson, and have a pesky problem (or solution!), don't hesitate to post it in the book discussion group here: http://j.mp/jcdiscuss and I may include it in the next release of this book.

Jackson Version:

Note that this book covers only the 2.x version of Jackson, not the earlier 1.x releases.

Early Access

Following the LeanPub credo, publish early and often, I am publishing this book even though only 2 chapters (and 2 appendices) have been written. As an early buyer you can purchase the book at bargain price. As more chapters are completed and published, the minimum price will go up.
