您尝试解析的日期格式不正确。您提供的要求格式是 yyyy-MM-dd'T'HH:mm:ssX.
此格式需要时区数字 - 即使该数字为零 ('0')。
一个解决方法是创建第二个 SimpleDateFormat，它使用后备格式将 'Z' 字符视为文字并忽略它。如果您第一次尝试解析失败，请捕获异常并尝试使用此格式解析 - yyyy-MM-dd'T'HH:mm:ss'Z'.
您还需要覆盖时区以强制使用 UTC。
类似于：
try {
d = input.parse(articleList[5].publishedAt)
}
catch (e: ParseException) {
try {
val fallback = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'")
fallback.timeZone = TimeZone.getTimeZone("UTC")
d = fallback.parse(articleList[5].publishedAt)
catch (e2: ParseException) {
// TODO handle error
}
}
相关：
- simpledateformat parsing date with 'Z' literal
- Converting ISO 8601-compliant String to java.util.Date
java.time
由于您已经在使用 java.time 中的 LocalDateTime（无论是内置的还是通过后向移植，ThreeTenABP），只需坚持使用 java.time 并忘记有关遗留日期时间的一切 class 就像 Date 和 SimpleDateFormat。它将为您提供更简单的代码，对所有人都有好处。
对不起，我只会写Java代码。不过我相信你 t运行slate。
String articleList5PublishedAt = "2019-10-09T09:02:00Z";
Instant timelinePoint = Instant.parse(articleList5PublishedAt);
Instant now = Instant.now();
Duration elapsedTime = Duration.between(timelinePoint, now);
System.out.println(timelinePoint);
System.out.println(now);
System.out.println(elapsedTime.toMinutes());
当我刚才运行这段代码时，输出是：
2019-10-09T09:02:00Z
2019-10-09T13:17:01.291404Z
255
对于时间轴上的一个点，Instant class 是正确的使用方式。 LocalDateTime 无法在时间轴上定义一个点。此外，来自 JSON 响应的字符串 2019-10-09T09:02:00Z 直接解析为 Instant，因此通过这种方式，所有内容都可以很好地组合在一起。

您尝试解析的日期格式不正确。您提供的要求格式是 yyyy-MM-dd'T'HH:mm:ssX.
此格式需要时区数字 - 即使该数字为零 ('0')。
一个解决方法是创建第二个 SimpleDateFormat，它使用后备格式将 'Z' 字符视为文字并忽略它。如果您第一次尝试解析失败，请捕获异常并尝试使用此格式解析 - yyyy-MM-dd'T'HH:mm:ss'Z'.
您还需要覆盖时区以强制使用 UTC。
类似于：
try {
d = input.parse(articleList[5].publishedAt)
}
catch (e: ParseException) {
try {
val fallback = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'")
fallback.timeZone = TimeZone.getTimeZone("UTC")
d = fallback.parse(articleList[5].publishedAt)
catch (e2: ParseException) {
// TODO handle error
}
}
相关：
- simpledateformat parsing date with 'Z' literal
- Converting ISO 8601-compliant String to java.util.Date
java.time
由于您已经在使用 java.time 中的 LocalDateTime（无论是内置的还是通过后向移植，ThreeTenABP），只需坚持使用 java.time 并忘记有关遗留日期时间的一切 class 就像 Date 和 SimpleDateFormat。它将为您提供更简单的代码，对所有人都有好处。
对不起，我只会写Java代码。不过我相信你 t运行slate。
String articleList5PublishedAt = "2019-10-09T09:02:00Z";
Instant timelinePoint = Instant.parse(articleList5PublishedAt);
Instant now = Instant.now();
Duration elapsedTime = Duration.between(timelinePoint, now);
System.out.println(timelinePoint);
System.out.println(now);
System.out.println(elapsedTime.toMinutes());
当我刚才运行这段代码时，输出是：
2019-10-09T09:02:00Z 2019-10-09T13:17:01.291404Z 255
对于时间轴上的一个点，Instant class 是正确的使用方式。 LocalDateTime 无法在时间轴上定义一个点。此外，来自 JSON 响应的字符串 2019-10-09T09:02:00Z 直接解析为 Instant，因此通过这种方式，所有内容都可以很好地组合在一起。
