推荐答案
It is a ISO 8061 日期时间
实际上,至少在 Java8 中,解析它非常简单,因为有一个预定义的 DateTimeFormatter
.这里有一个小的单元测试作为演示:
Actually, at least in Java8 it's very simple to parse that one as there is a predefined DateTimeFormatter
. Here a small unit test as demonstration:
import org.junit.Test;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
import static org.junit.Assert.assertEquals;
public class DateTimeFormatterTest {
@Test
public void testIsoDateTimeParse() throws Exception {
// when
final ZonedDateTime dateTime = ZonedDateTime.parse("2013-03-31T16:46:38.000Z", DateTimeFormatter.ISO_DATE_TIME);
// then
assertEquals(2013, dateTime.getYear());
assertEquals(3, dateTime.getMonthValue());
assertEquals(31, dateTime.getDayOfMonth());
assertEquals(16, dateTime.getHour());
assertEquals(46, dateTime.getMinute());
assertEquals(38, dateTime.getSecond());
assertEquals(ZoneOffset.UTC, dateTime.getZone());
}
}
在 Java8 之前,我会看看 Converting符合 ISO 8601 的字符串到 java.util.Date 和 definitley 默认使用 Joda Time 与某事.喜欢:
Prior to Java8, I would take a look at Converting ISO 8601-compliant String to java.util.Date and definitley default to using Joda Time with sth. like:
final org.joda.time.DateTime dateTime = new org.joda.time.DateTime.parse("2013-03-31T16:46:38.000Z");
顺便说一句,不要使用 new DateTime("2013-03-31T16:46:38.000Z")
因为它会使用您的默认时区,这可能不是您想要的.
BTW, don't use new DateTime("2013-03-31T16:46:38.000Z")
as it will use your default time zone, which is probably not what you want.
