java-8 - 使用 Java 时间在 Predicate 中将日期时间字符串解析为日期

Question

CSV 文件中有一个字符串字段，格式如下: 2008-04-11 00:00:00
我需要将其转换为日期，以便我可以在 Predicate 中执行以下计算，以验证日期输入错误。

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
Predicate<Client> clientBirth = p -> Period.between(LocalDate.parse(p.getBirth().replaceAll("-", "/"), formatter),LocalDate.now()).getYears() >= 100;

但是它在 CSV 文件的第一行中给出了错误。

Exception in thread "main" java.time.format.DateTimeParseException: Text '2008/04/11 00:00:00' could not be parsed at index 2

提前致谢。

Answer 1

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.S");

使用上面作为 CSV 的日期时间格式是 2008-04-11 00:00:00不是 dd/MM/yyyy .
