private InstReservation instReservation;

private InstrumentReservationService instReservationService;//服务层接口



get、set省略



action中有一个方法调用了工具类如下：

TimeCompute.compute(instReservation,instReservationService);



让静态方法处理。

public static void compute(InstReservation instReservation,InstReservationService instReservationService) {

		Calendar calendar = Calendar.getInstance(TimeZone.getDefault());

		calendar.setTime(instReservation.getStartTime());

		/**

		 * 开始时间

		 * */

		int i = calendar.get(Calendar.DAY_OF_WEEK);// 星期

		int j = calendar.get(Calendar.HOUR_OF_DAY);// 小时

		int k = calendar.get(Calendar.MINUTE);// 分钟

		int l = calendar.get(Calendar.DAY_OF_MONTH);// 日

		System.out.println(l + "日、" + "星期" + i + "、" + j + "时、" + k + "分");

		Calendar calendar2 = Calendar.getInstance();

		calendar.setTime(instReservation.getEndTime());

		/**

		 * 结束时间

		 * */

		int m = calendar2.get(Calendar.DAY_OF_WEEK);// 星期

		int n = calendar2.get(Calendar.HOUR_OF_DAY);// 时

		int o = calendar2.get(Calendar.MINUTE);// 分

		int p = calendar2.get(Calendar.DAY_OF_MONTH);// 日

		System.out.println(p + "日、" + "星期" + m + "、" + n + "时、" + o + "分");

		



		if (...) {



			instReservation.setTimeA("XXX");

			instReservationService.update(instReservation);

			System.out.println("XXA区间");

			System.out.println("XX");

		}
