时间带比较

时间比较有很多种思路，这是一种转化成Long值去比较的思路：

 

// 有效时间带的检查
			String startTime = (String) session
					.getAttribute(LoanConstants.START_TIME);
			String endTime = (String) session
					.getAttribute(LoanConstants.END_TIME);
			if (userInfo != null && startTime != null && endTime != null) {
				long startDateTime = Long.parseLong(startTime.replaceAll(":",
						"").replaceAll("：", ""));
				long endDateTime = Long.parseLong(endTime.replaceAll(":", "")
						.replaceAll("：", ""));
				String nowTime = LoanDateUtil.formatDate(new Date(), "HHmmss");
				if (Long.parseLong(nowTime) <= startDateTime
						|| Long.parseLong(nowTime) >= endDateTime) {
					// 迁移到通知画面
					forward = mapping.findForward("login");
					session.setAttribute(LoanConstants.USER_INFO_KEY, null);
					return forward;
				}
