为啥要自研

市面主流定时器计划任务语法: cron ,但是使用起来非常难受,设计的比较非人性话语法,我想一般人都没几个记住的,都是靠在线生成工具进行使用的,而且只能持续执行不是有限执行,下面举几个cron的案例:

具体想了解的可以自行百度,我试图记住语法,但是因为太混乱了,时间一长就忘了,没法只能到网上工具里生成,而且很多有限的场景没法生成因为cron不支持只执行几次或者有规律的执行,为了解决以上的问题,我自己研究了一套(free time)定时器计划任务语法

语法格式

语法: 0,0,7,0,0,0,0,- 长度为8

对应时间: 秒,分,时,天,星期,月,年,执行计划

执行计划

数值: 执行几次

n: 循环执行

^n: 时间乘阶 2*2,4*2,8*2....

^数值: 时间乘阶几次 ^2 那么就是2*2,4*2

符号

~: 区间 1~4 那么就会执行1,2,3,4

/: 间隔 2/5 那么从2开始下次之后就从5开始执行

[]: 分段 [1,5,10,12] 分别在这几个时间点执行

模式

模式就是可以: 月底,月初,每周几,星期末,年末,节假日等,(可以支持自定义扩张需要对外提供生成器)

执行计划: m(循环执行) ,m数值(有限执行)

begin: 时间底(天底,周末,月底,年底)

end: 时间初(天初,周初,月初,年初)

point(?): 指定时间点,指定每月5号,每周3,每2天

以上是基础模式,其他模式需要自定义(节假日,特殊日期等)

注意: 在模式的基础上还可以配合时间比如: (每天2点1分10秒执行)

语法演示

基本操作

都是以当前时间为基准进行添加时间

当前时间+1分钟后执行(执行2次)

0,1,0,0,0,0,0,2
(2022-09-24 16:22:59,2022-09-24 16:23:59)

当前时间+5小时后执行(循环执行)

0,0,5,0,0,0,0,n
(2022-09-24 21:23:09,2022-09-25 02:23:09)

当前时间+1天后执行

0,0,0,1,0,0,0,n
(2022-09-25 16:24:07,2022-09-26 16:24:07)

当前时间+1星期(7天)后执行

0,0,0,0,1,0,0,n
(2022-10-01 16:25:19,2022-10-08 16:25:19)

当前时间加1天1小时1分1秒后执行

1,1,1,1,0,0,0,2
(2022-09-25 17:38:57,2022-09-26 18:39:58)

当前时间分钟递增执行(循环)

0,1,0,0,0,0,0,^n

当前时间分钟递增执行(次数)

0,1,0,0,0,0,0,^2

符号操作

符号操作有~和[]以及/ 可以配合有限和循环n,不能使用递增

区间执行(循环)

0,2~5,0,0,0,0,0,n(每2分钟3分钟…5分钟各执行一次,然后反复)

间隔执行

0,0,3/0,1,0,0,0,n (3小时后,每天执行一次)

分段执行

0,0,[2,5,8],0,0,0,0,n (当前时间每2,5,8小时执行一次,然后反复)

符号操作还可以和基本操作组合,原理就是相加

0,10,[2,5,8],0,0,0,0,n(当前时间每2,5,8小时加10分钟执行一次,然后反复)

模式操作

在[年,月,星期,天,小时,分支,秒]底执行

年底执行5次

0,0,0,0,0,0,end,mode5
(2023-12-31 23:59:59 ,2024-12-31 23:59:59)

月底执行,一共执行两次

0,0,0,0,0,end,0,mode2
(2022-10-31 23:59:59,2022-11-31 23:59:59)

每个星期日底执行(循环)

0,0,0,0,end,0,0,mode
(2022-10-02 23:59:59,2022-10-09 23:59:59)

每天底执行

0,0,0,end,0,0,0,mode
(2022-09-24 23:59:59 , 2022-09-25 23:59:59)

每小时底执行

0,0,end,0,0,0,0,mode
(2022-09-23 15:59:59,2022-09-23 16:59:59)

每分钟底执行

0,end,0,0,0,0,0,mode
(2022-09-23 14:20:59,2022-09-23 14:21:59)

每秒底执行

end,0,0,0,0,0,0,mode (可能看不出来,所以当做每秒执行就行)
(2022-09-23 14:21:26,2022-09-23 14:22:25)

在[年,月,星期,天,小时,分支,秒]初执行

每年初执行(2次)

0,0,0,0,0,0,begin,mode2
(2023-01-01 00:00:00, 2024-01-01 00:00:00)

没月初执行

0,0,0,0,0,begin,0,mode2
(2022-10-01 00:00:00, 2022-11-01 00:00:00)

每星期初执行

0,0,0,0,begin,0,0,mode
(2022-09-26 00:00:00,2022-10-03 00:00:00)

每天初执行

0,0,0,begin,0,0,0,mode
(2022-09-25 00:00:00,2022-09-26 00:00:00)

每小时初执行

0,0,begin,0,0,0,0,mode
(2022-09-24 16:00:00,2022-09-24 17:00:00)

每分钟初执行

0,begin,0,0,0,0,0,mode
(2022-09-24 15:35:00,2022-09-24 15:36:00)

每秒钟初执行

begin,0,0,0,0,0,0,mode (可能看不出来,所以当做每秒执行就行)
(2022-09-24 15:35:17,2022-09-24 15:35:18)

指定时间执行

我们可以使用模式中的point(?) 来完成,而point除了在星期占位特殊可以指定下个星期几执行,在其他占位也是可以指定时间

每个星期2晚上11点执行

0,0,point(23),0,point(2),0,0,mode
(2022-09-27 22:00:00,2022-10-04 22:00:00)

每天凌晨2点执行

0,0,point(2),point(1),0,0,0,mode
(2022-09-25 02:00:00,2022-09-26 02:00:00)

模式组合

注意: end ,begin 和point 不能同时出现,但是我们可以和基本模式作进行混合

-59,1,-2,end,0,0,0,mode (每天晚上10点执行)

0,0,8,begin,0,0,0,mode (每天早上8点执行)

0,0,8,point(2),0,0,0,mode (每2天8点执行)
