Hi @jyothibontu19 

 

You can use the code as below :

 

@AttributeDefinition(
			name = "Cron Expression", 
			description = "Cron expression used by the scheduler", 
			type = AttributeType.STRING)
	public String cronExpression() default "0 * * * * ?";

You can refer the following documents for more info on the same :

    Refer below code for cron expression at OSGI config.

    @AttributeDefinition(
            name = "scheduler.expression",
            description = "Cron expression used by the scheduler",
            type = AttributeType.STRING)
    public String scheduler_expression() default "0 0 14 1/1 * ? *";

    Scheduler will run daily at 2pm with this deafult expression. Next dates be like 12022-09-09 Fri 14:00:002.2022-09-10 Sat 14:00:003.2022-09-11

      You can declare it in the properties.

       

      package sling.docu.examples;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Service;
import org.apache.felix.scr.annotations.Property;

@Component
@Service(value = Runnable.class)
@Property( name = "scheduler.expression", value = "0 * * * * ?")
public class ScheduledCronJob implements Runnable {

	/** Default log. */
    protected final Logger log = LoggerFactory.getLogger(this.getClass());

    public void run() {
    	log.info("Executing a cron job (job#1) through the whiteboard pattern");
    }
//
}
