In this chapter, you were introduced to the various processing models for the JSON content and some of the popular Java-based JSON processing frameworks available today. This chapter is essential for understanding how the JSON-based request and response messages are bound to the Java model while building REST APIs later in the book.

This chapter is not meant for recommending any specific JSON framework for your application, but to help you understand the popular frameworks available today for processing JSON and what they have to offer.

In the next chapter, we will build our first REST service by using JAX-RS APIs.
