java - DateTimeFormatter 创建模式

Question

这个问题已经有答案了:

How to get start and end range from list of timestamps? (2 个回答)

Converting ISO 8601-compliant String to java.util.Date (31 个回答)

已关闭 4 年前。

我有这个日期:2008-01-10T11:00:00-05:00 (日期、T(分隔符)、时间、偏移量)

我有这个:DateTimeFormatter.ofPattern("yyyy-MM-ddSEPARATORHH-mm-ssOFFSET")

我用这个table创建我的模式。

但是，我找不到如何注释SEPARATOR (T) 和偏移。

对于 OFFSET 存在这样的: x zone-offset offset-x +0000; -08; -0830; -08:30; -083015; -08:30:15; ，但不知道如何使用x获取-08:30

这里有一个小例子，展示了如何解析您的字符串并接收偏移量:

public static void main(String[] args) {
    // this is what you have, a datetime String with an offset
    String dateTime = "2008-01-10T11:00:00-05:00";
    // create a temporal object that considers offsets in time
    OffsetDateTime offsetDateTime = OffsetDateTime.parse(dateTime);
    // just print them in two different formattings
    System.out.println(offsetDateTime.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME));
    System.out.println(offsetDateTime.format(DateTimeFormatter.ofPattern("dd.MM.yyyy HH:mm:ss")));
    // get the offset from the object
    ZoneOffset zonedOffset = offsetDateTime.getOffset();
    // get its display name (a String representation)
    String zoneOffsetString = zonedOffset.getDisplayName(TextStyle.FULL_STANDALONE, Locale.getDefault());
    // and print the result
    System.out.println("The offset you want to get is " + zoneOffsetString);
}

Please pay attention to the code comments, they explain what is done. Printing the OffsetDateTime two times in the middle of the code is just done in order to show how you can deal with a single datetime object along with different formatters.
