将日期转换为时间戳

Question

如何在Java中将日期转换为时间戳？

这一行给出了以下错误： ＆＃34;构造函数Timpestamp（Date）未定义＆＃34;

Timestamp timestamp = new Timestamp(Date);

Answer 1

试试这个：

import java.util.Date;
import java.sql.Timestamp;

public Timestamp convertDateToTimestamp(Date date) {
    Timestamp timestamp = null;
    if (date != null) {
        timestamp = new Timestamp(date.getTime());
    }
    return timestamp;
}

Answer 2

Timestamp timestamp = new Timestamp(new Date().getTime());

或

Timestamp timestamp = new Timestamp(date.getTime());
