1. 概述
前面两篇分别讲述了SpringBoot整合Quartz实现简单和动态定时任务，在实际工作中，通常需要周末或节假日不需要执行某个定时任务，Quartz也为我们提供了相应的方法。本文主要介绍SpringBoot整合Quartz如何实现排除指定日期。
Quartz中有个Calendar接口，其实现方法有7个，如下所示：
AnnualCalendar：用于排除一年中的某一天
BaseCalendar：实现了Calendar基本功能
CronCalendar：用于排除CronExpression中某个时间，例如需要排除上午8点到下午5点，可以使用* * 0-7,18-23 ? * *
DailyCalendar：用于排除一天中的某个时间段
HolidayCalendar：用于排除指定假日(指定日期)
MonthlyCalendar：用于排除一月的某天
WeeklyCalendar：用于排除一周的某天
