java中List对象的排序，可以使用对象的属性排序

	private static void ListSortVersion(List<PlaMonthProPlanEntity> list) {
		Collections.sort(list, new Comparator<PlaMonthProPlanEntity>() {
			@Override
			public int compare(PlaMonthProPlanEntity o1, PlaMonthProPlanEntity o2) {
				try {
					int  dt1 = Integer.parseInt(o1.getVersion());
					int  dt2 = Integer.parseInt(o2.getVersion());
					if (dt1> dt2) {
						return -1;
					} else if (dt1< dt2) {
						return 1;
					} else {
						return 0;
					}
				} catch (Exception e) {
					e.printStackTrace();
				}
				return 0;
			}
		});
	}
