Java_获取两个日期中间的日期

yyyyMMdd形式

private List<Date> dateSplit(Date startDate, Date endDate)  
            throws Exception {
		
        if (!startDate.before(endDate)&&startDate.compareTo(endDate)==1){  
            throw new Exception("开始时间应该在结束时间之后");  
        }  
              
        Long spi = endDate.getTime() - startDate.getTime();  
        Long step = spi / (24 * 60 * 60 * 1000);// 相隔天数  
  
        List<Date> dateList = new ArrayList<Date>();  
        dateList.add(startDate);  
        for (int i = 1; i <= step; i++) {  
            dateList.add(new Date(dateList.get(i - 1).getTime()  
                    + (24 * 60 * 60 * 1000)));// 比上一天+一  
        }  
        return dateList;  
    }

yyyyMMddHH形式

	private List<Date> dateHHMMSplit(Date startDate, Date endDate)  
            throws Exception {
		
        if (!startDate.before(endDate)&&startDate.compareTo(endDate)==1){  
            throw new Exception("开始时间应该在结束时间之后");  
        }  
              
        Long spi = endDate.getTime() - startDate.getTime();  
        Long step = spi / (10 * 60 * 1000);// 相隔小时数 
  
        List<Date> dateList = new ArrayList<Date>();  
        dateList.add(startDate);  
        for (int i = 1; i <= step; i++) {  
            dateList.add(new Date(dateList.get(i - 1).getTime()  
                    + (10 * 60 * 1000)));// 加1小时
        }  
        return dateList;  
    }
