时间戳转换：
一、十位时间戳和时间互转

1.十位时间戳和Stirng互转

/*     * String(yyyy-MM-dd HH:mm:ss)转10位时间戳     * 2011-05-09 11:49:45   结果：1304912985     */    public static Integer StringToTimestamp(String time){        int times = 0;        try {              times = (int) ((Timestamp.valueOf(time).getTime())/1000);              System.out.println("times:"+times);        } catch (Exception e) {              e.printStackTrace();          }        if(times==0){            System.out.println("String转10位时间戳失败");        }        return times;     }    /*     * 10位int型的时间戳转换为String(yyyy-MM-dd HH:mm:ss)     * 1304912985 结果：2011-05-09 11:49:45     */    public static String timestampToString(Integer time){        //int转long时，先进行转型再进行计算，否则会是计算结束后在转型        long temp = (long)time*1000;        Timestamp ts = new Timestamp(temp);          String tsStr = "";          DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");          try {              tsStr = dateFormat.format(ts);              System.out.println(tsStr);          } catch (Exception e) {              e.printStackTrace();          }        return tsStr;      }

2.十位时间戳和date互转

/*     * 10位时间戳转Date     * 1304912985    结果：2011-05-09 11:49:45.0     */    public static Date TimestampToDate(Integer time){        long temp = (long)time*1000;        Timestamp ts = new Timestamp(temp);          Date date = new Date();          try {              date = ts;              System.out.println(date);          } catch (Exception e) {              e.printStackTrace();          }          return date;    }    /*     * Date类型转换为10位时间戳     * new Date()  结果：1493286148     */    public static Integer DateToTimestamp(Date time){        Timestamp ts = new Timestamp(time.getTime());        Integer timestamp = (int) ((ts.getTime())/1000);        System.out.println("timestamp:"+timestamp);        return timestamp;    }

二、十三位时间戳和时间互转 String类型 / 时间戳

/*     * 时间戳转换为时间  13位     * 1493175590107  结果：2017-04-26 10:59:50.107     */      public static String stampToDate(String s){            String res;            SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");            long lt = new Long(s);            Date date = new Date(lt);            res = simpleDateFormat.format(date);            System.out.println(res);            return res;        }        /*          * 将时间转换为时间戳 13位         * 2017-04-26 10:59:50.107   1493175590107         */            public static String dateToStamp(String s) throws Exception{            String res;            SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");            Date date = simpleDateFormat.parse(s);            long ts = date.getTime();            res = String.valueOf(ts);            System.out.println(res);            return res;        }

三、Stirng格式转date
1、String(yyyy-MM-dd HH:mm:ss) 转 Date Tue May 04 12:34:23 CST 2010

    /*     * String(yyyy-MM-dd HH:mm:ss) 转 Date     * String date = "2010-05-04 12:34:23"; 结果：Tue May 04 12:34:23 CST 2010     */     public static Date StringToDate(String time) throws Exception {        Date date = new Date();        // 注意format的格式要与日期String的格式相匹配        DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");        try {            date = dateFormat.parse(time);            System.out.println(date.toString());        } catch (Exception e) {            e.printStackTrace();        }        return date;    }
