Learn JSON with Jackson

Jackson can do a lot processing JSON used to its full capacity

Learn Jackson through practice

JSON is a simple but effective standard for storing and sending data between applications. Its lightweight, easy-to-read, and quick-to-parse format makes it pretty much the strandard when building APIs or any kind of system that exchanges data.

Although JSON itself is language-independent, we still need to read and write the content using a library. In Java, the Jackson library has become almost synonymous with JSON parsing, and it’s the default choice in many frameworks, including Spring.

In this course, we’ll hit the ground running with Jackson, go through basic serialization/deserialization for different types, focusing in on data binding.

Then, we’ll also go further into more advanced scenarios, including custom serializers, JSON views, processing nested objects and complex data structures, error handling, and the alternative approaches for processing JSON – the Tree model and the Streaming API.

Actual coding practice through a Java project – definitely the best way to learn how to process JSON using Jackson

The essential path to working with JSON in Java, professionally. The 3 modules build a solid base of understanding the benefits of Jackson, and how to address the most common scenarios when processing JSON data.

Everything you need to understand the Jackson API for processing JSON in Java.
