public static Map<String, String> getWeekDate() {
		Map<String, String> map = new HashMap<String, String>();
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

		Calendar cal = Calendar.getInstance();
		// 设置一个星期的第一天,按中国的习惯一个星期的第一天是星期一
		cal.setFirstDayOfWeek(Calendar.MONDAY);
		// 获得当前日期是一个星期的第几天
		int dayWeek = cal.get(Calendar.DAY_OF_WEEK);
		if (dayWeek == 1) {
			dayWeek = 8;
		}

		cal.add(Calendar.DATE, cal.getFirstDayOfWeek() - dayWeek);// 根据日历的规则,给当前日期减去星期几与一个星期第一天的差值
		Date mondayDate = cal.getTime();
		String weekBegin = sdf.format(mondayDate);

		cal.add(Calendar.DATE, 4 + cal.getFirstDayOfWeek());
		Date sundayDate = cal.getTime();
		String weekEnd = sdf.format(sundayDate);

		map.put("mondayDate", weekBegin);
		map.put("sundayDate", weekEnd);
		return map;
	}

这个编码习惯不规范
