在特定日期使用 (Spring @Scheduled) 运行作业

Question

I have a customer check job. I could not find how to automatically set the job time to run on 10am only on Monday, Friday and Saturday. Is there a possible way to set it using Spring @Scheduled ?

Answer 1

I found the solution like this:

@Scheduled(cron = "0 0 10 * * MON,FRI,SAT")
public void dailyScheduleJob() {
    /*
    your code here
    */
}

Additionally, if the requested days are sequential such as Monday to Friday(a job running only on weekdays), this expression is shorter:

@Scheduled(cron = "0 0 10 * * MON-FRI")
public void dailyScheduleJob() {
    /*
    your code here
    */
}

It is also possible to represent days with numbers from 1-7 . In this case 1 will be SUN, and 7 will be SAT and the same cron job above can be written like this:

@Scheduled(cron = "0 0 10 * * 2-6")
public void dailyScheduleJob() {
    /*
    your code here
    */
}

Answer 2

To run a job every Monday, Friday and Saturday at 10:00 AM:

@Scheduled(cron = "0 10 * * 1,5,6")
public void scheduleTaskUsingCronExpression() {
    // ...
}
