Java8 LocalDateTime序列化问题

public class LocalDateTimeConfig { public static void configureJackson() { ObjectMapper jackson2ObjectMapper = JsonUtils.getMapper(); JavaTimeModule timeModule = new JavaTimeModule(); timeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd"))); timeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))); timeModule.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd"))); timeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))); jackson2ObjectMapper .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false) .setSerializationInclusion(JsonInclude.Include.NON_NULL) .registerModule(timeModule) .registerModule(new ParameterNamesModule()) .registerModule(new Jdk8Module()); } }
