Java时间和时间戳的相互转换

https://www.cnblogs.com/mstk/p/5511057.html

时间转换为时间戳:

/* 
 * 将时间转换为时间戳
 */    
public static String dateToStamp(String s) throws ParseException{
     String res;
     SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
     Date date = simpleDateFormat.parse(s);
     long ts = date.getTime();
     res = String.valueOf(ts);
    return res;
}

时间戳转换为时间:

/* 
 * 将时间戳转换为时间
 */
public static String stampToDate(String s){
      String res;
      SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
      long lt = new Long(s);
      Date date = new Date(lt);
      res = simpleDateFormat.format(date);
     return res;
}
