Java 当前日期判断节假日

获取今天日期（today）

	SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	Date date = new Date();
	String today = dateFormat.format(date);

获取明天日期（tomorrow）

	Date today = new Date(System.currentTimeMillis() + 1000 * 60 * 60 * 24);
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMMdd");
    String yesterday = simpleDateFormat.format(today);//获取明天日期

获取昨天日期（yesterday）

	Date today = new Date(System.currentTimeMillis() - 1000 * 60 * 60 * 24);
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMMdd");
    String yesterday = simpleDateFormat.format(today);//获取昨天日期
