Source Link

Document

Method for registering a module that can extend functionality provided by this mapper; for example, by adding providers for custom serializers and deserializers.

Usage

From source file:com.mastfrog.acteur.mongo.impl.JacksonMongoDB.java

@Override
public ObjectMapper configure(ObjectMapper om) {
    om.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);
    SimpleModule sm = new SimpleModule("mongo", new Version(1, 0, 0, null, "com.timboudreau", "trackerapi"));
    sm.addSerializer(new ObjectIdSerializer());
    sm.addDeserializer(ObjectId.class, new ObjectIdDeserializer());
    om.registerModule(sm);
    return om;/*from   w w w.  ja  v  a  2 s  .c o m*/
