Annotations for Scheduling.

Scheduling can be done in imperative style as follows:

Fixed Rate: 

FixedRate.builder()
     .interval(Duration.ofSeconds(2))
     .task(inv -> System.out.println("Executed every 2 seconds"))
     .build();
Cron expression: 
Cron.builder()
     .expression("0 45 9 ? * *")
     .task(inv -> System.out.println("Executed every day at 9:45"))
     .build();

The same can be achieved in a declarative style as follows:

Fixed Rate: 

@Scheduling.FixedRate("PT2M")
void scheduledMethod() {
    System.out.println("Executed every 2 seconds");
}
Cron expression: 
@Scheduling.Cron("0 45 9 ? * *")
void scheduledMethod() {
    System.out.println("Executed every day at 9:45");
}

This class contains only the declarative scheduling annotations. Use FixedRate.builder() and Cron.builder() for imperative scheduling.
