java后端把毫秒數轉化成日期的方法----java中實現日期的加減

java后端把毫秒數轉化成日期的方法：
date.setTime(Long.valueOf(map.get("hfsj").toString()));
map.put("hfsj",DateFormatUtils.format(date,"yyyy-MM-dd")); //commons-lang3  3.7


java中實現日期的加減：
        String oneHoursAgoTime="";
        Date dt = new Date();
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd-HH");
        Calendar rightNow = Calendar.getInstance();
        rightNow.setTime(dt);
        //rightNow.add(Calendar.DATE, -1);
        rightNow.add(Calendar.HOUR, -1);
        Date dt1=rightNow.getTime();
        oneHoursAgoTime = sdf.format(dt1);
        return oneHoursAgoTime;

public List<WpSsgc> getByBmmbId(String bmmbId) {
        List<WpSsgc> ssgcsList = ssgcMapper.selectByBmmbId(bmmbId);
        for (WpSsgc ssgc:ssgcsList){
            Date date = new Date();
            date.setTime(ssgc.getSsrj());
            ssgc.setSsrjStr(DateFormatUtils.format(date,"yyyy-MM-dd"));
        }
        return ssgcsList;
    }

 

 毫秒數轉字符串 ：select FROM_UNIXTIME(1593322599965/1000, "%Y-%m-%d")

SELECT DATE_FORMAT(NOW(),'%Y-%m-%d %H:%i:%s')

基於 中國標准時間 的字符串格式轉換 

 

時間格式轉換不太熟，記錄一下

    private static String parseTime( String dateStr ) { // 轉換時間格式 ==> "Wed Nov 21 2018 00:00:00 GMT+0800 (中國標准時間)" String parseDate; // 定義一個用於返回的變量 // 字符串轉Date // 定義一個 用於格式化字符串的變量 SimpleDateFormat sdf = new SimpleDateFormat( "EEE MMM dd yyyy HH:mm:ss 'GMT+0800 (中國標准時間)'", Locale.US ); Date date = new Date(); // 創建 Date 對象 try { date = sdf.parse( dateStr ); // 將目標字符串按指定格式解析 } catch (ParseException e) { log.info( "時間格式轉換錯誤" + date.toString() ); // 打印錯誤日志，也可以用 "System.out.println()" } //Date轉字符串 sdf = new SimpleDateFormat( "yyyy-MM-dd" ); // 再次指定轉換的格式 parseDate = sdf.format( date ); // 按指定日期格式轉換 //parseDate: 2018-11-21 return parseDate; // 返回處理后的結果 }
