Cron-Expressions--cron expressions

In order of
Seconds (0~59)
Minutes (0~59)
Hours (0~23)
Days (months) (0~31, but you need to consider the number of days of your month)
Month (0~11)
Days (weeks) (1~7 1=sun or Sun,mon,tue,wed,thu,fri,sat)
7. Year (1970-2099)

Each of these elements can be a value (such as 6), a continuous interval (9-12), a time interval (8-18/4) (/= every 4 hours), a list (1,3,5), and a wildcard character. Because the "date in the month" and "date in the week" are mutually exclusive, one of the two elements must be set.
0 0 10,14,16 * *? 10 o'clock in the morning, 2 o'clock in the afternoon, 4 O ' Day
0 0/30 9-17 * *? Every half hour for nine to five working hours
0 0 12? * WED means every Wednesday noon 12 o'clock
Some sub-expressions can contain ranges or lists
For example: subexpression (Day (week)) can be "Mon-fri", "Mon,wed,fri", "Mon-wed,sat"
The "*" character represents all possible values
Therefore, "*" in the sub-expression (month) represents the meaning of each month, "*" in the subexpression (Day (week)) represents every day of the week

The "/" character is used to specify the increment of the numeric value
For example: "0/15" in sub-expressions (minutes) means starting from the No. 0 minute, every 15 minutes
"3/20" in the sub-expression (minutes) means that every 20 minutes (it is the same as "3,23,43") starting from the 3rd minute

“？ "Character is used only for days (months) and days (weeks) of two sub-expressions, indicating that no value is specified
When one of the 2 sub-expressions is assigned a value, in order to avoid a conflict, you need to set the value of another subexpression to "? ”

The "L" character is used only for days (months) and days (weeks) of two sub-expressions, which is the abbreviation for the word "last"
But it has a different meaning in two sub-expressions.
In the day (month) subexpression, "L" represents the last day of the one-month
In the day (week) Self-expression, "L" represents the last day of one weeks, the SAT
If there is something specific before "L", it has other meanings.
For example: "6L" means the 6th day of the month, and "Fril" means the last Friday of the month.
Note: When using the "L" parameter, do not specify a list or range, as this can cause problems
Cron expressions are used to configure Crontrigger instances. A cron expression is a string that consists of 7 sub-expressions. Each sub-expression describes a separate schedule detail. These sub-expressions are separated by a space and are represented separately;
