@Documented
public @interface Scheduled
Annotation that marks a method to be scheduled. Exactly one of the
cron(), fixedDelay(), or fixedRate()
attributes must be specified.
The annotated method must expect no arguments and have a
void return type.
Processing of @Scheduled annotations is performed by
registering a ScheduledAnnotationBeanPostProcessor. This can be
done manually or, more conveniently, through the <task:annotation-driven/>
element or @EnableScheduling annotation.
