推荐答案

你有两个选择。

1 - 使用sql date的getTime方法来获取sql date对象并构造utils日期

或

2 - 调用getTimeStamp而不是getDate，它将返回sql timeStamp类的对象实际上是java.util.Date的子类

You have two options.
1 - Take sql date object and construct utils date using the getTime method of sql date
or
2 - call getTimeStamp instead of getDate , It will return object of sql timeStamp class that is actually child class of java.util.Date

1 -  Date d1 = new Date(rs.getDate("date_time").getTime());
2 -  Date d2 = rs.getTimestamp("date_time");
