Java EE Becomes JSON Friendly

JSON enhancements in Java EE allow for working with JSON in a much simpler way than before. The addition of JSON processing and binding has turned it into a first-class citizen of Java EE. Use APIs to serialize and deserialize Java objects, to and from JSON documents. JSON-B does for JSON, what JAXB did for XML. No longer do you have to rely upon third-party libraries to work with JSON. Most features will work out of the box, with sensible defaults.

We will cover the following topics in this chapter:

• REST prefers JSON
• JSON first-class citizen
• No more third-party libraries
• JSON processing:
  • JSON-P 1.1
  • JSON pointer and JSON patch
  • JSON merge patch
  • JSON collectors
• JSON binding:
  • Similar to JAXB with default mappings
  • Standardize current solutions (Jackson, Gson, and so on)
  • Mapping between classes and JSON
  • Customisation APIs
• A few tips in practice
