One of Jackson Misc. datatype modules. Supports JSON serialization and deserialization of "org.json" JSON library datatypes, most commonly seen in Android SDK.

Usage

Maven dependency

To use module on Maven-based projects, use following dependency:

<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-json-org</artifactId>
  <version>2.11.0</version>
</dependency>

(or whatever version is most up-to-date at the moment)

Registering module

Like all standard Jackson modules (libraries that implement Module interface), registration is done as follows (Jackson 2.x up to 2.9)

// import com.fasterxml.jackson.datatype.jsonorg.JsonOrgModule;

ObjectMapper mapper = new ObjectMapper()
    .registerModule(new JsonOrgModule());

OR, the new method added in 2.10 (old method will work with 2.x but not 3.x):

ObjectMapper mapper = JsonMapper.builder()
    .addModule(new JsonOrgModule())
    .build();

after which functionality is available with all normal Jackson operations, like:

JSONObject ob = mapper.readValue("{\"a\":{\"b\":3}, \"c\":[9, -4], \"d\":null, \"e\":true}",
                JSONObject.class);
assertEquals(4, ob.length());
JSONObject ob2 = ob.getJSONObject("a");
assertEquals(1, ob2.length());
