java - 如何在同一输入日期上添加日期和时间？

Question

如果添加日期则输入时间默认修改为 01/01/1970 08:00:00 提交期间

例如:
DispDeb = 02/08/2019 和 DispFin 02/08/2019 但时间为 DispDeb 08:00 和 DispFin 12: 00

我的问题

如果在 DispDeb 02/08/2019 中添加日期，并在 inputText 中添加 Time 08:00 更改我在 DispDeb 和 DispFin 中的日期，并在我的提交中添加到表中 DispDeb 01/01/1970 08 :00 和 DispFin 01/01/1970 12:00 错误javax.DateTimeConverter转换器

我不太确定你想从这个问题中做什么，但你可以简化转换

DispDeb = 02/08/2019 and  DispDeb 08:00

像这样:

DateTimeFormatter DATE_TIME_FORMATTER = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm")
                .withZone(ZoneId.systemDefault());

String date = "2019/12/19";
String time = "12:00";

String dateTime = date + " " + time;

LocalDateTime localDateTime = LocalDateTime.parse(dateTime, DATE_TIME_FORMATTER);
System.out.println(localDateTime);

Timestamp timestamp = Timestamp.valueOf(localDateTime);
System.out.println(timestamp);

希望有帮助
