* So what is cron expression?
* second minute hour day month week year
The format of a Cron expression is as follows.
Second Minute Hour Day Month Week Year
Seconds: 0-59
Minute: 0-59
hour: 0-23
Day: 1-31
Month: 1-12
Week: 1-7 (0-6 sometimes)
Year: Specify your own
If you want to express every second or every minute or something like that, use the * symbol in that position;
if you want to express more than one such as every 15 minutes and every 30 minutes, you can write:`15, 30`.
For the rest of the wildcard characters, please Google them yourself
