[英]Jackson unable to parse ISO8601
We get a HttpResponse with a date as one json attribute, the date is formatted in ISO8601 (eg 2020-03-13T00:00:35.570+0000) but Jackson throws following Exception:我们得到一个带有日期作为一个 json 属性的 HttpResponse,日期格式为 ISO8601(例如 2020-03-13T00:00:35.570+0000),但 Jackson 抛出以下异常:
java.time.format.DateTimeParseException: Text '2020-03-13T00:00:35.570+0000' could not be parsed at index 23
I`ve written the following Test (spock) which fails reproduceable.我已经编写了以下无法重现的测试(spock)。 I need to know how to parse the date.
我需要知道如何解析日期。 Thanks for your help!
谢谢你的帮助!
class TestJackson extends Specification{
def 'test date format'(){
given:
def jsonString = """{"myDate":"2020-03-13T00:00:35.570+0000"}"""
and:
def objectMapper = new ObjectMapper()
.registerModule(new JavaTimeModule())
.enable(SerializationFeature.INDENT_OUTPUT)
.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
when:
def resp = objectMapper.readValue(jsonString, Response)
then:
resp.myDate != null
}
@Data
@NoArgsConstructor
@AllArgsConstructor
static class Response {
ZonedDateTime myDate
}
}
The Test uses following Dependencies:测试使用以下依赖项:
Jackson is not the issue here;杰克逊不是这里的问题; you'd get the same exception if you called
ZonedDateTime.parse("2020-03-13T00:00:35.570+0000")
.如果您调用
ZonedDateTime.parse("2020-03-13T00:00:35.570+0000")
您会得到相同的异常。 According to the API , ZonedDateTime
uses DateTimeFormatter.ISO_ZONED_DATE_TIME
to parse.根据API ,
ZonedDateTime
使用DateTimeFormatter.ISO_ZONED_DATE_TIME
来解析。 ISO_ZONED_DATE_TIME
is ISO_ZONED_DATE_TIME
是
a date-time with offset and zone, such as '2011-12-03T10:15:30+01:00[Europe/Paris]'
带有偏移量和区域的日期时间,例如 '2011-12-03T10:15:30+01:00[Europe/Paris]'
The value you were trying to parse has an offset but no zone so you need to convert it to OffsetDateTime
, which uses DateTimeFormatter.ISO_OFFSET_DATE_TIME
to parse.您尝试解析的值具有偏移量但没有区域,因此您需要将其转换为
OffsetDateTime
,它使用DateTimeFormatter.ISO_OFFSET_DATE_TIME
进行解析。 DateTimeFormatter.ISO_OFFSET_DATE_TIME
...parses a date-time with an offset, such as '2011-12-03T10:15:30+01:00'.
...解析具有偏移量的日期时间,例如“2011-12-03T10:15:30+01:00”。
