Welche Methoden gibt es, um eine Zeichenfolge in Java in ein Datum zu konvertieren?

/**
     *     指定当前时间-指定时间是否大于30秒
     */
    
    //SimpleDateFormat
    private static void m1() throws ParseException {
        String endTime = "哈哈2020-02-07 18:58:02.0你好";//支持特殊格式转换
        String format = "哈哈yyyy-MM-dd HH:mm:ss";
        SimpleDateFormat sdf = new SimpleDateFormat(format);
        Date edate = sdf.parse(endTime);
        Date now = new Date();
        String nowStr = DateFormatUtils.format(now, format);
        if(DateUtils.addSeconds(edate, 30).before((now))){
            logger.info("true endTime={} now={}",endTime, nowStr);
        }else{
            logger.info("false endTime={} now={}",endTime, nowStr);
        }
    }

    //DateUtils
    private static void m3() throws ParseException {
        String endTime = "2020-02-07 18:58:02.0";
        String format = "yyyy-MM-dd HH:mm:ss";
        Date edate = DateUtils.parseDate(endTime, format, "yyyy-MM-dd HH:mm:ss.SSS");//支持多格式匹配
        Date now = new Date();
        String nowStr = DateFormatUtils.format(now, format);
        if(DateUtils.addSeconds(edate, 30).before((now))){
            logger.info("true endTime={} now={}",endTime, nowStr);
        }else{
            logger.info("false endTime={} now={}",endTime, nowStr);
        }
    }

    //DateTimeFormatter
    private static void m2(){
        String endTime = "2020-02-07 18:58:02";
        String format = "yyyy-MM-dd HH:mm:ss";
        LocalDateTime now = LocalDateTime.now();
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern(format);
        String nowStr = now.format(dateTimeFormatter);
        if(LocalDateTime.parse(endTime, dateTimeFormatter)
                .plusSeconds(30).isBefore(LocalDateTime.now())){//链式编程
            logger.info("true endTime={} now={}",endTime, nowStr);
        }else{
            logger.info("false endTime={} now={}",endTime, nowStr);
        }
    }
