问题描述

您好，我无法理解如何进行转换
"2020-03-11 16:27:31" 到"2020-03-11T16:27:31 + 00:00" .

Hi I am not able to understand how to convert
"2020-03-11 16:27:31" to "2020-03-11T16:27:31+00:00".

我对此一无所知.

日期给定，格式为"2020-03-11 16:27:31"

我希望以这种格式超过日期 "2020-03-11T16:27:31 + 00:00"

I want above date in this format "2020-03-11T16:27:31+00:00"

推荐答案

以下是您可以执行所需操作的方式(如果使用的是Java8):

Here the way you can do what you need (if you're using java8):

    String date = "2020-03-11 16:27:31";
    String pattern = "yyyy-MM-dd HH:mm:ss";
    // formatter with spaces before and after 'T'
    DateTimeFormatter f0 = new DateTimeFormatterBuilder()
            .parseCaseInsensitive()
            .append(DateTimeFormatter.ISO_LOCAL_DATE)
            .appendLiteral(' ')
            .appendLiteral('T')
            .appendLiteral(' ')
            .append(DateTimeFormatter.ISO_LOCAL_TIME)
            .optionalStart().appendOffset("+HH:MM", "+00:00").optionalEnd()
            .toFormatter();

    // formatter without spaces before and after 'T'
    DateTimeFormatter f1 = new DateTimeFormatterBuilder()
            .parseCaseInsensitive()
            .append(DateTimeFormatter.ISO_LOCAL_DATE_TIME)
            .optionalStart().appendOffset("+HH:MM", "+00:00").optionalEnd()
            .toFormatter();
    OffsetDateTime offsetDateTime = LocalDateTime.parse(date, DateTimeFormatter.ofPattern(pattern))
            .atOffset(ZoneOffset.ofHoursMinutes(0, 0));
    String result = offsetDateTime.format(f1);

但是我建议您阅读@deHaar推荐的java.timi手册.

But I suggest you to read java.timi manual as @deHaar recomended.
