由于时间戳不起作用而将LocalDateTime序列化

Question

我正在尝试通过添加以下配置来将LocalDateTime序列化为TimeStamp。但是它不起作用。我正在使用 jackson-datatype-jsr310 支持Java 8 date /时间数据类型。

@Configuration
@Slf4j
public class JacksonConfig {

        private static final Logger LOGGER = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return (Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) -> {
            jacksonObjectMapperBuilder.serializerByType(LocalDateTime.class, new LocalDateTimeSerializer());
            jacksonObjectMapperBuilder.deserializerByType(LocalDateTime.class, new LocalDateTimeDeserializer());
        };
    }

    public static class LocalDateTimeDeserializer extends JsonDeserializer<LocalDateTime> {

        @Override
        public LocalDateTime deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JsonProcessingException {
            final String localDate = p.getText().trim();
            log.info("Deserialize");
            JavaTimeModule javaTimeModule = new JavaTimeModule();
            ObjectMapper objectMapper = new ObjectMapper();
            objectMapper.registerModule(javaTimeModule);
            objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

            if (NumberUtils.isParsable(localDate)) {
                return LocalDateTime.ofInstant(Instant.ofEpochMilli(Long.parseLong(localDate)), TimeZone.getDefault().toZoneId()).withNano(0);

            }
            return LocalDateTime.parse(localDate, DateTimeFormatter.ISO_LOCAL_DATE_TIME);
        }
    }

    public static class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime> {

            public final DateTimeFormatter DT_PATTERN = DateTimeFormatter
                    .ofPattern("yyyy-MM-dd HH:mm:ss");

            @Override
            public void serialize(LocalDateTime value, JsonGenerator jgen,
                                  SerializerProvider provider) throws IOException {
                log.info("Serialize");
                jgen.writeString(value.format(DT_PATTERN));
            }
        }
    }

当我解析LocalDateTime时，我得到{2016,12,21,15,53,57,178}而不是1482306837178。

这是我的测试模型类Foo

public class Foo{
    private String name;
    private LocalDateTime creation_time;
}
