How to write a cron expression that runs every 5 mins from 9:30 to 4:00 am on weekdays in spring/java?

I have a Spring Boot application that has a cron expression for a job that I would like to run on weekdays MON-FRI between 9:30 am to 4:00 pm every 5 mins.

But looks like the cron expression is not correct.

application.properties

job.signal.cron=0 0/5 9:30-16 * * MON-FRI

Error at startup:

Caused by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'findSignal': For input string: "9:30" '9:30-16' in cron expression "0 0/5 9:30-16 * * MON-FRI"

Solution

You can try this

0 30-55/5 9 * * MON-FRI
0 */5 10-15 * * MON-FRI
0 0 16 * * MON-FRI
