public static Map<String, String> getMonToSunday() {
        Calendar preWeekSundayC = Calendar.getInstance();
        Calendar preWeekMondayCal = Calendar.getInstance();
        //上周天时间
        preWeekSundayC.set(Calendar.DAY_OF_WEEK, 1);
        //设置时间成本周第一天(周日)
        preWeekMondayCal.set(Calendar.DAY_OF_WEEK, 1);
        //上周一时间
        preWeekMondayCal.add(Calendar.DATE, -6);
        //转化为日期
        Date preWeekMonday = preWeekMondayCal.getTime();
        Map<String, String> result = new HashMap<>();
        result.put("mon", DateUtil.format(preWeekMonday, "yyyy-MM-dd") + " 00:00:00");
        result.put("sun", DateUtil.format(preWeekSundayC.getTime(), "yyyy-MM-dd") + " 00:00:00");
        return result;
    }

本周一及本周天时间

 public static String getSunday() {
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        Calendar c = Calendar.getInstance(Locale.CHINA);
        c.setFirstDayOfWeek(Calendar.MONDAY);
//当前时间，貌似多余，其实是为了所有可能的系统一致
        c.setTimeInMillis(System.currentTimeMillis());
//         System.out.println("当前时间:" + format.format(c.getTime()));
//         c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
//         System.out.println("周一时间:" + format.format(c.getTime()));
        c.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
        // System.out.println("本周天时间:" + format.format(c.getTime()));
        return format.format(c.getTime());
    }
