用JAVA相关类转换。代码如下:
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(NumberUtils.getLong(mss) * 1000);
//mss即是从服务器获取的时间戳
SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String date = sf.format(calendar.getTime());
//date即是已转换好的时间。
/**
* 时间戳转换成日期格式字符串
* @param seconds 精确到秒的字符串
* @param formatStr
* @return
*/
public static String timeStamp2Date(String seconds,String format) {
if(seconds == null || seconds.isEmpty() || seconds.equals("null")){
return "";
}
if(format == null || format.isEmpty()) format = "yyyy-MM-dd HH:mm:ss";
SimpleDateFormat sdf = new SimpleDateFormat(format);
return sdf.format(new Date(Long.valueOf(seconds+"000")));
}
/**
* 日期格式字符串转换成时间戳
* @param date 字符串日期
* @param format 如：yyyy-MM-dd HH:mm:ss
* @return
*/
public static String date2TimeStamp(String date_str,String format){
try {
SimpleDateFormat sdf = new SimpleDateFormat(format);
return String.valueOf(sdf.parse(date_str).getTime()/1000);
} catch (Exception e) {
e.printStackTrace();
}
return "";
}
/**
* 取得当前时间戳（精确到秒）
* @return
*/
public static String timeStamp(){
long time = System.currentTimeMillis();
String t = String.valueOf(time/1000);
return t;
}
// 输出结果：
// timeStamp=1417792627
// date=2014-12-05 23:17:07
// 1417792627
public static void main(String[] args) {
String timeStamp = timeStamp();
System.out.println("timeStamp="+timeStamp);
String date = timeStamp2Date(timeStamp, "yyyy-MM-dd HH:mm:ss");
System.out.println("date="+date);
String timeStamp2 = date2TimeStamp(date, "yyyy-MM-dd HH:mm:ss");
System.out.println(timeStamp2);
}
//将时间戳转换为时分秒
String date = "142925";
SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
Date currentTime = new Date();
String dateString = dateFormat.format(currentTime);
System.out.println(dateString);
