Task scheduling using cron expression from properties file

Question

I have written a cron job:

@Scheduled(cron="${process.virtual.account.start}") public void ecomProcessVirAccOrderPaymentsScheduler() {     LOGGER.info("Start --->" + this.getClass().getCanonicalName() + ".ecomProcessVirAccOrderPaymentsScheduler() Method");     schedulerJobHelper.ecomProcessVirAccOrderPaymentsScheduler();     LOGGER.info("End --->" + this.getClass().getCanonicalName() + ".ecomProcessVirAccOrderPaymentsScheduler() Method"); } 

I want to get the cron attribute used with @Scheduled annotation to be populated from a external properties file. Currently I am fetching it from a property file inside the application scope. I am able to fetch the value, but not able to use it with @Schedule annotation.

Answer 1

it is working in spring boot.

@Scheduled(cron="${cronExpression}") private void testSchedule()  {     System.out.println("Helloooo"); } 

in application.properties I have a property like this as below:

cronExpression=* * * ? * *
