Example 6 with JsonDeserializer

use of com.fasterxml.jackson.databind.JsonDeserializer in project presto by prestodb.

the class TestLocalProperties method testJsonSerialization.

@Test
public void testJsonSerialization() throws Exception {
    ObjectMapper mapper = new ObjectMapperProvider().get().registerModule(new SimpleModule().addDeserializer(ColumnHandle.class, new JsonDeserializer<ColumnHandle>() {

        @Override
        public ColumnHandle deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
            return new ObjectMapperProvider().get().readValue(jsonParser, TestingColumnHandle.class);
        }
    }));
    TestingColumnHandle columnHandle = new TestingColumnHandle("a");
    LocalProperty<ColumnHandle> property1 = new ConstantProperty<>(columnHandle);
    assertEquals(property1, mapper.readValue(mapper.writeValueAsString(property1), new TypeReference<LocalProperty<ColumnHandle>>() {
    }));
    LocalProperty<ColumnHandle> property2 = new SortingProperty<>(columnHandle, SortOrder.ASC_NULLS_FIRST);
    assertEquals(property2, mapper.readValue(mapper.writeValueAsString(property2), new TypeReference<LocalProperty<ColumnHandle>>() {
    }));
    LocalProperty<ColumnHandle> property3 = new GroupingProperty<>(ImmutableList.of(columnHandle));
    assertEquals(property3, mapper.readValue(mapper.writeValueAsString(property3), new TypeReference<LocalProperty<ColumnHandle>>() {
    }));
}

Example 7 with JsonDeserializer

use of com.fasterxml.jackson.databind.JsonDeserializer in project web3sdk by FISCO-BCOS.

the class ObjectMapperFactory method configureObjectMapper.

private static ObjectMapper configureObjectMapper(ObjectMapper objectMapper, boolean shouldIncludeRawResponses) {
    if (shouldIncludeRawResponses) {
        SimpleModule module = new SimpleModule();
        module.setDeserializerModifier(new BeanDeserializerModifier() {

            @Override
            public JsonDeserializer<?> modifyDeserializer(DeserializationConfig config, BeanDescription beanDesc, JsonDeserializer<?> deserializer) {
                if (Response.class.isAssignableFrom(beanDesc.getBeanClass())) {
                    return new RawResponseDeserializer(deserializer);
                }
                return deserializer;
            }
        });
        objectMapper.registerModule(module);
    }
    objectMapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
    objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    return objectMapper;
}
