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.arpnetworking.test.junitbenchmarks.GCShapshotSerializerTest.java

@Test
public void testSerialization() {
    final SimpleModule module = new SimpleModule();
    module.addSerializer(GCSnapshot.class, new GCSnapshotSerializer());
    final ObjectMapper mapper = ObjectMapperFactory.createInstance();
    mapper.registerModule(module);

    final GCSnapshot testSnapshot = DataCreator.createGCSnapshot();

    final JsonNode jsonNode = mapper.valueToTree(testSnapshot);
    Assert.assertTrue(jsonNode.isObject());
    Assert.assertThat(jsonNode.get("accumulatedInvocations").asLong(), Matchers.greaterThanOrEqualTo(0L));
    Assert.assertThat(jsonNode.get("accumulatedTime").asLong(), Matchers.greaterThanOrEqualTo(0L));
