java⾃动⽣成⼀年中⼯作⽇和休息⽇（公休⽇及假期国家法定假⽇）
说明
计算周期为每年的12⽉1号⾄下⼀年的12⽉之前(即12⽉1号⽣成下⼀年的假期，因为⼀次性⽣成，避开⾼并发时段，适合12⽉1号凌晨执⾏)。
计算时间为⼀年的休息⽇(假期)时间，可⾃⼰通过代码的注释选择是否包括公休⽇。
本计算基于规则实现，基本是正确的，但是有时⼀年的放假不按规则出牌，这时候就只能⾃⼰修改了，只需要根据⽇期修改Map集合对应key的值即可。
本计算⽅法⼀共基于两个类实现，⼀个计算类VacationDayCalculate，⼀个⽇历类Lunar(还有⼀个⽇期辅助处理类DataUtils)代码注释较全，请注意查看有助于理解，main⽅法在计算类VacationDayCalculate最下⾯，可运⾏测试。
