Now I have set a schedule task using cron expression.
However I don't know how to write a cron expression to execute the same task at 14:30 and 17:45.
Even I tried to write "0 30,45 14,17 * * ? *", but it is not the result what I want.
Write the same expression on two separate lines:
0 30 14 * * ? *
0 45 17 * * ? *

I have a requirement where my scheduler has to run for every hour between 9 AM to 12 PM everday and then it runs once by 3PM and 5 PM respectively.
How can i make my CRON expression to work according to the requirement
So far i have tried with below cron expression
#Scheduled(cron="0 0 9-12 * * *")
But that runs for every hour from 9 AM - 12 PM
How can i modify it to make it run once by 3 PM and 5 PM also.
I have tried by combining two cron expressions like below but that dint work.
#Scheduled(cron="0 0 9-12 * * *, 0 0 3 * * *")
Can i give 2 cron expressions through 2 #Scheduled like below
#Scheduled(cron="0 0 9-12 * * *")
#Scheduled(cron="0 0 9-12 * * *")
public void myMethod() {}
Would that be a feasible solution?
Can anybody help me with this?
#Schedules annotation can be used to set multiple calendar-based timer expressions.
This annotation will get rid of the redundancy of writing the same
method multiple times.
In the following example, the first expression sets a timer to expire on the last day of every month. The second expression sets a timer to expire every Friday at 11:00 PM.
#Schedules ({
#Schedule(dayOfMonth="Last"),
#Schedule(dayOfWeek="Fri", hour="23")
})
public void doPeriodicCleanup() { ... }
So i have a cron job that runs and executes fine (hence why no path is shown) at:
*/15 * * * *
but I don't want that as it means it runs at every fifteen minutes past 0 of the hour according to crontab.guru which gives tasks run at 15,30 and 45 minutes.
This is actually what I want:
1/15 * * * *
which according to crontab.guru should begin the 15 minutes at 1 minute past the hour and run the tasks at 16, 31 and 46 minutes.
Now the problem is when I crontab -e to set up the cron job of 1/15 * * * * I get a bad minute error from crontab, yet as i say in my opening lines using */15 * * * * returns no error from crontab and the task is executed. Why is this?.
You could do 1,16,31,46 * * * * to run the jobs at 1, 16, 31 and 46 minutes every hour.
I want to set a timer at 9:00 / 16:30. But one cron can not realize it.
So i need two cron to realize it. The corn is as follows:
cron1: * 30 16 * * *
cron2: * * 9 * * *
I want to set cron by springboot #Schedule like this
#Scheduled(cron = "0 0 2 * * ?")
public void sayHello(){}
But it seems that can not support two #Scheduled label on one method or two cron in one label.
The so low method is as follow, Any better advice？
#Scheduled(cron = "* 30 16 * * ?")
public void sayHello(){}
#Scheduled(cron = "* * 9 * * ?")
public void subSayHello(){sayHello();}
I think it is difficult because of the different min and different hour,
if the cron run in the same hour or min, it will be easy.
Such as:
"* 0,30 9 * * ?"
"* 0 9,16 * * ?"
Or you can see this link Cron expression to run job twice a day at different time?
Can anyone suggest a way to set a Cron trigger to run every 1 hour?
I tried to do something like this:
#Scheduled(cron = "0 0 0/1 1/1 * ? *")
but when I run the server I get Error :
Error 404--Not Found
What is wrong in this cron?
Try any one of these:
0 0 0/1 * * ?
0 0 * * * ?
This means 0 seconds 0 minutes on change of every hour.
I've used the following cron statement:
#Scheduled(cron = "59 * * * * *")
now I have this configuration my my scheduler:
<task:scheduled ref="task" method="run" cron="0 45 22 * * *" />
when this task is executed ? and how I can change it to do this task every minute
This task is executed at 22:45:00 every day, every week, every month.
To execute a task every minute, use
0 * * * * *
The accepted answer is correct for spring. Other than that, one should be careful whether the target system uses 6 or 5-digits cron.
With 5-digits-crons
0 * * * * schedules to be run "at minute 0" (hence every hour).
The correct answer in this case should be either
* * * * *
or
*/1 * * * *
