需要唯一约束 id和月份

ava月份计算比较

Calendar calDelM = Calendar.getInstance();
		calDelM.set(Calendar.MONTH, 0);
		System.out.println(calDelM.get(Calendar.MONTH));
		
		calDelM.add(Calendar.MONTH, -1);
		System.out.println(calDelM.get(Calendar.MONTH));

		
		
		
		// ix 遍历需要删除的月份
		int isdel = calDelM.get(Calendar.MONTH);
		int ix = 8;// 缓存最小月份

		Calendar calDelM2 = Calendar.getInstance();
		calDelM2.set(Calendar.MONTH, ix);
		ix = calDelM2.get(Calendar.MONTH);

	
		// ix
