json-org

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());
