Cron Expressions for Quartz
A cron expression has at least 6 (or possibly 7) time elements that have a space separation.
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 "Day of the Week" are two elements that are mutually exclusive, one of them must be set.

Some sub-expressions can include some range or list
For example: Sub-expressions (days (weeks)) 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 every one months, "*" 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 starting from the 3rd minute, every 20 minutes (it is the same as "3,23,43").
“？ "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 the conflict, you need to set the value of a sub-expression 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
Assuming that there is detailed content before "L", it has other meanings.
For example: "6L" means the 6th day of the month, "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
The field agrees with the value of the special character
