Deserialize “Zulu” time in ISO8601 format in jackson

由 霸气de小男生 提交于 2019-12-10 18:16:36
问题 I have a need to de-serialize time of format 2016-11-28T10:34:25.097Z using Jackson into ZonedDateTime of Java8. I believe I correctly configured ObjectMapper (a factory method): @Bean ObjectMapper getObjectMapper() { ObjectMapper objectMapper = new ObjectMapper(); // some other config... objectMapper.registerModule(new JavaTimeModule()); return objectMapper; } And I have in my code for DTO a field @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ") private

问题 This question already has an answer here : Java8 - how to know if daylight savings is on now (1 answer) Closed 3 years ago . How to ask a java.time.ZonedDateTime object if Daylight Saving Time (DST) applies to its moment or if standard time applies? 回答1: @Jon's answer is good. Just want to mention there is ZoneRules#isDaylightSavings available. ZonedDateTime zdt = ...; ZoneRules rules = zdt.getZone().getRules(); boolean isDst = rules.isDaylightSavings(zdt.toInstant()); And possible duplicate

问题 Migrating Joda time to Java 8 Joda: UserObject user = new UserObject() user.setCreatedAt(new DateTime(rs.getTimestamp("columnName")));` Migrating to Java 8 This is my code; it does compile; I am doubtful if it works: ZonedDateTime.ofInstant(rs.getTimestamp("columnName").toLocalDateTime().toInstant(ZoneOffset.UTC),ZoneId.of("UTC"))); In some cases, the date is wrong. Any advice? 回答1: tl;dr To track a moment in history, use Instant as the type of your class member variable. Specifically, this

Whats the difference between java.util.Date and Zoneddatetime?

由 微笑、不失礼 提交于 2019-12-08 11:06:23
问题 While using util.date and giving date with time to service from browser and then saving to db and taking it back it gives different date time against setting zoneddatetime directly from service. Any help would be appreciated.. 回答1: tl;dr Whats the difference between java.util.Date and Zoneddatetime? Date represents a moment in UTC, while ZonedDateTime represents a moment in a particular time zone. Date is a terrible class, riddled with design flaws, that should never be used, while

How to use some Jackson Deserializer in own custom Deserializer?

由 时间秒杀一切 提交于 2019-12-07 13:20:54
问题 I am struggling with mentioned in the question issue. I need to create some custom deserializer which is more or less type conversion from the standard deserializer (reason is that ZonedDateTime is working for my input, but I don't want to change the type to ZonedDateTime , but keep LocalDateTime ). Bascially what I want to do in my deserializer is to: Deserialize using ZonedDateTime deserializer (which I found, in reality, is custom InstantDeserializer ) Use .toLocalDateTime and return it.

ZonedDateTimeDeserializer is missing in jackson jsr310

问题 I'm parsing a ZonedDateTime using like this: @JsonSerialize(using = ZonedDateTimeSerializer.class) private ZonedDateTime expirationDateTime; I need to be able to properly deserialize this date. However, there is no deserializer for this that is provided by jackson: com.fasterxml.jackson.datatype.jsr310.deser Is there a reason why it's missing? What is the most common workaround?
