Example 11 with ObjectMapperProvider

use of io.airlift.json.ObjectMapperProvider in project presto by prestodb.

the class TestMarker method testJsonSerialization.

@Test
public void testJsonSerialization() throws Exception {
    TestingTypeManager typeManager = new TestingTypeManager();
    TestingBlockEncodingSerde blockEncodingSerde = new TestingBlockEncodingSerde(typeManager);
    ObjectMapper mapper = new ObjectMapperProvider().get().registerModule(new SimpleModule().addDeserializer(Type.class, new TestingTypeDeserializer(typeManager)).addSerializer(Block.class, new TestingBlockJsonSerde.Serializer(blockEncodingSerde)).addDeserializer(Block.class, new TestingBlockJsonSerde.Deserializer(blockEncodingSerde)));
    Marker marker = Marker.above(BIGINT, 0L);
    assertEquals(marker, mapper.readValue(mapper.writeValueAsString(marker), Marker.class));
    marker = Marker.exactly(VARCHAR, utf8Slice("abc"));
    assertEquals(marker, mapper.readValue(mapper.writeValueAsString(marker), Marker.class));
    marker = Marker.below(DOUBLE, 0.123);
    assertEquals(marker, mapper.readValue(mapper.writeValueAsString(marker), Marker.class));
    marker = Marker.exactly(BOOLEAN, true);
    assertEquals(marker, mapper.readValue(mapper.writeValueAsString(marker), Marker.class));
    marker = Marker.upperUnbounded(BIGINT);
    assertEquals(marker, mapper.readValue(mapper.writeValueAsString(marker), Marker.class));
