java.time.format.DateTimeParseException：无法以 ddMMyyyyhhmmss 格式从 TemporalAccessor 获取 ZonedDateTime [重复]

我在将字符串格式化为 ZonedDateTime 时遇到问题。

我的客户希望日期采用 ddMMyyyyhhmmss 等格式，没有分隔符或类似的内容。

这就是我到目前为止所做的

import java.time.format.DateTimeFormatter;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZonedDateTime;


public class MyClass {
    public static void main(String args[]) {

        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("ddMMyyyyhhmmss");
        String test = formatter
        .format(ZonedDateTime.now()).toString();
        System.out.println(test);
        ZonedDateTime a = ZonedDateTime.parse(test, formatter);
        System.out.println(a.toString());
    }
}

虽然它正确地生成了字符串，但在创建 LocalDateTime 变量的解析过程中发生了错误：

28032019100707

在 Stack Overflow 上搜索，我看到同一问题的一些答案建议使用 LocalDateTime 类作为中间，然后解析为 ZonedDateTime，但它仍然不起作用，抛出相同的错误。

我还尝试更改使用以下过程初始化 DateTimeFormatter 的方式：

DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("ddMMyyyyhhmmss")
                          .toFormatter()
                          .withZone(ZoneId.systemDefault());

但它仍然不起作用。我该如何修复它？

你要：

  String test = ZonedDateTime.now().format(formatter);
