I am trying to schedule a task in Spring which is to be run everyday at midnight. I followed the official guide from Spring and made the scheduler class as below:
@Component
public class OverduePaymentScheduler {
@Scheduled(cron = "0 0 0 * * *")
public void trackOverduePayments() {
System.out.println("Scheduled task running");
}
}
However the task does not run when the clock hits 12am. I got the cron expression from the documentation for quartz scheduler at this link.
The scheduler is executed fine if I change the cron expression to "*/10 * * * * *" which runs every ten seconds.
So what am I doing wrong?
These are valid formats for cron expressions:
0 0 * * * *
= the top of every hour of every day.*/10 * * * * *
= every ten seconds.0 0 8-10 * * *
= 8, 9 and 10 o'clock of every day.0 0 6,19 * * *
= 6:00 AM and 7:00 PM every day.0 0/30 8-10 * * *
= 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every
day.0 0 9-17 * * MON-FRI
= on the hour nine-to-five weekdays0 0 0 25 12 ?
= every Christmas Day at midnightThe pattern is:
second, minute, hour, day, month, weekday
So your answer is:
0 0 0 * * *
