如何将时间戳转换为适当的日期格式?

2022-01-13 00:00:00 timestamp date java

我有 TimeStamp，我需要将其转换为应该匹配此模式的 Data 类型对象 - 2016-11-16T18:42:33.049Z".我该怎么做?

I have the TimeStamp and I need to convert it to Data type object that should match this pattern - "2016-11-16T18:42:33.049Z". How can I do that?

推荐答案

Date d = new Date((long)timestamp*1000);

将创建一个 Date 实例.稍后显示它是另一回事.

will create a Date instance. Displaying it later is another thing.

我想这就是你想要的:

DateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.mmm'Z'");
System.out.println(f.format(date));

测试:

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Main {
    public static void main(String[] args) throws Exception {

        Date d = new Date((long)1481723817*1000);
        DateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.mmm'Z'");
        System.out.println(f.format(d));
    }
}
