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.

Let's see how to serialize:

Book book = new Book(); book.setName("Jodd in Action); book.setYear(2018); book.setAuthors(List.of(new Author("Igor"))); String json = JsonSerializer.create() .include("authors") .serialize(book);

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?

• 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…
