=nil{returnnil,err}return&SpecSchedule{Second:second,Minute:minute,Hour:hour,Dom:dayofmonth,Month:month,Dow:dayofweek,},nil} 该函数主要是将cron表达式映射为“Second, Minute, Hour, Dom, Month, Dow”6个时间维度的结构体SpecSchedule。 SpecSchedule是实现了方法“Next(time.Time) time.Time”的结构体,...
Timer 1 expired Timer 2 stopped timer1表示2秒后到期,在此之前都是阻塞状态,2秒后<-timer1.C接收到信号,执行下面的打印语句。 timer2表示1秒后到期,但是中途被Stop掉了,相当于清除了定时功能。 有了这个背景之后,我们再来看run函数的里层for循环。 接收到c.add信道 case newEntry := <-c.add: // 添加...

atcrontab.org. The examples in the link have five fields, and 1 minute as the finest granularity, but our cron scheduling supports an enhanced format with six fields, allowing for second-level precision. Tools likecrontab.gurucan help in constructing patterns but remember to account for the ...
1. cron表达式的基本格式 cron表达式是⼀个字符串，字符串以5或6个空格隔开，分为6或7个域，每⼀个域代表⼀个含义，cron有如下两种语法格式：second minute hour dayofmonth month dayofweek year second minute hour dayofmonth month dayofweek 各个字段的含义 字段允许值允许的特殊字符 秒(second)0-59整数...
