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
JSONObjectandJSONArrayclasses, - 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…
