Jackson Module which provides custom serializers and deserializers for JTS Geometry objects using the GeoJSON format

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

<dependency>
  <groupId>com.bedatadriven</groupId>
  <artifactId>jackson-datatype-jts</artifactId>
  <version>1.0</version>
</dependency>    

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

To use JTS geometry datatypes with Jackson, you will first need to register the module first (same as with all Jackson datatype modules):

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

After registering JTS module, Jackson Databind will be able to write Geometry instances as GeoJSON and and read GeoJSON geometries as JTS Geometry objects.

To write a Point object as GeoJSON:

GeometryFactory gf = new GeometryFactory();
Point point = gf.createPoint(new Coordinate(1.2345678, 2.3456789));
String geojson = objectMapper.writeValueAsString(point);

You can also read GeoJSON in as JTS geometry objects:

InputStream in;
Point point = mapper.readValue(in, Point.class);
