java - 将日期转换为时间戳

Question

如何在java中将日期转换为时间戳？

这一行给我以下错误: “构造函数 Timpestamp(Date) 未定义”

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;
}
