java.time.format.DateTimeParseException：无法以格式ddMMyyyyhhmmss从TemporalAccessor获取ZonedDateTime

Question

我在将字符串格式化为ZonedDateTime时遇到麻烦。
我的客户希望使用ddMMyyyyhhmmss之类的日期作为日期，而没有分隔符或类似的内容。
这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());
    }
}

当它正确生成字符串时，在创建LocalDateTime变量的解析过程中会发生错误

28032019100707

在SO上搜索，我发现对同一问题的一些答案建议使用LocalDateTime类作为中间类，然后解析为ZonedDateTime，但它仍然无法正常工作，并抛出相同的错误。我还尝试通过此过程更改初始化DateTimeFormatter的方式

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

但是它仍然无法正常工作。我知道我肯定会缺少一些愚蠢的东西，但是我看不到。有人能指出我正确的方向吗？

你要 ：

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