The first time @Scheduled method is called when my project just started(it's not fully up).Can i defined when my @Scheduled method should be called first time(not using initial delay).I want all my @Scheduled method to start execution first time when my server is up.So my startup time will be reduced.
I have used fixed delay Scheduler:
@Scheduled(fixedDelay = 1800000) // runs in every 30min
public void schedulerFunction(){}
You could implement ApplicationListener and wait for a ContextReadyEvent:
@Component
public class YourClassHavingScheduledMethodimplements ApplicationListener<ContextRefreshedEvent> {
private boolean contextInitialized = false;
@Scheduled(...)
public void someScheduledMethod() {
if(this.contextInitialized) {
// Execute logic here
}
}
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
this.contextInitialized = true;
}
}
