JavaScript Object Notation (aka JSON) is a very popular lightweight data-interchange format. Jodd JSON is a lightweight library for (de)serializing Java objects into and from JSON.
Before you say: "Yet another one?", please check what makes Jodd JSON unique. The power of the library is its control over the process of serialization and parsing; ease of use and great performances.

Quick Start

Let's see how to serialize:
Book book = new Book();
book.setName("Jodd in Action);
book.setAuthors(List.of(new Author("Igor")));
String json = JsonSerializer.create()
The resulting JSON may look like this:
"name" : "Jodd In Action",
"year" : 2018,
"authors" : [
{ "firstName" : "Igor" }
Parse the JSON back to Java:
Book book2 = new JsonParser()
.parse(json, Book.class);
Pretty simple, right? But don't get blinded by the simplicity, Jodd JSON is pretty powerful. Did I mention it is one of the fastest JSON frameworks out there?

Main features

  • simple syntax and fluent interface,
  • lazy parser that is super fast,
  • annotations for better conversion control,
  • convenient JSONObject and JSONArray classes,
  • powerful exclusion and inclusion rules,
  • serializer definition for types,
  • the only library that can handle any number size,
  • pretty formatting of the JSON output,
  • loose, more forgiving, parsing mode,
  • ways to address the keys and values of the Maps
  • flexible fine-tuning,
  • and more…
