/*
* 日历（Calendars） Quartz
* Calendar对象（不是java.util.Calendar对象）能够与被注册进Scheduler的Trigger关联
* 。Calendar对排除Trigger的时间段是很有用的，
* 例如，我们可以创建一个在2014-06-30上午9:30触发Job的Trigger，就在其中增加一个排除所有工作假期的Calendar。

//这个cal有问题，此处我本想设置成当天6月30日15点42分时算假期,不执行，但效果却是不论我怎么设置，都是不执行

// cal.set(cal.HOUR, 15);
// cal.set(cal.MINUTE,42);
// // cal.set(cal.SECOND,);
// //cal.set(cal.MILLISECOND, 0);

//②五一劳动节
Calendar laborDay = new GregorianCalendar();
