converting/parsing 字符串到日期时间 Java 时丢失日期

Question

DateTimeFormatter dateFormatter1 =
        DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");

String timestamp = "2021-02-03 23:22:23 +0000 UTC";

DateTime converted1 = dateFormatter1.parseDateTime(timestamp);

Invalid format: "2021-02-03 23:22:23 +0000 UTC" is malformed at " 23:22:23 +0000 UTC"
java.lang.IllegalArgumentException: Invalid format: "2021-02-03 23:22:23 +0000 UTC" is malformed at " 23:22:23 +0000 UTC"

将字符串解析为日期时间时出现异常 Java，有人可以帮忙吗？

尝试了各种格式，例如：

yyyy-MM-dd'T'HH:mm:ss'Z'
yyyy-MM-dd'T'HH:mm:ssZ
yyyy-MM-dd'T'HH:mm:ss.SSS'Z'
yyyy-MM-dd HH:mm:ss.SSS
(yyyy-MM-dd'T'HH:mm:ss'Z').withZone(UTC)

Answer 1

您的模式不正确。使用 yyyy-MM-dd HH:mm:ss Z z

import org.joda.time.DateTime;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class Main {
    public static void main(String[] args) {
        String timestamp = "2021-02-03 23:22:23 +0000 UTC";
        DateTimeFormatter fmtInput = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss Z z");

        DateTime dtSource = fmtInput.parseDateTime(timestamp);
        System.out.println(dtSource);
    }
}

输出：

2021-02-03T23:22:23.000Z
