Question

调用该代码时出现此异常：

String date = "2017-07-21T17:32:28Z";

LocalDateTime dateTime = LocalDateTime.parse(date, ISO_INSTANT);

ISO即时格式化程序，用于格式化或解析UTC中的即时消息， *例如“ 2011-12-03T10：15：30Z”。

我要检查日期字符串是否为有效日期，其格式为：yyyy-MM-dd'T'HH:mm:ssX

java.time.format.DateTimeParseException: Text '2017-07-21T17:32:28Z' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {MicroOfSecond=0, MilliOfSecond=0, InstantSeconds=1500658348, NanoOfSecond=0},ISO of type java.time.format.Parsed

Answer 1

您可以使用datetimeformatter轻松执行此任务。尝试以下修改后的代码

String date = "2017-07-21T17:32:28Z";

DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ISO_INSTANT;


Date testDate = Date.from(Instant.from(dateTimeFormatter.parse(date)));

System.out.print(testDate);

解析日期时出现java.time.format.DateTimeParseException
