java.lang.Objectorg.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor
public class ScheduledAnnotationBeanPostProcessor
Bean post-processor that registers methods annotated with @Scheduled
to be invoked by a TaskScheduler according
to the "fixedRate", "fixedDelay", or "cron" expression provided via the annotation.
This post-processor is automatically registered by Spring's
<task:annotation-driven> XML element, and also by the @EnableScheduling
annotation.
Auto-detects any SchedulingConfigurer instances in the container,
allowing for customization of the scheduler to be used or for fine-grained control
over task registration (e.g. registration of Trigger tasks.
See @EnableScheduling Javadoc for complete usage details.

public void setScheduler(Object scheduler)
TaskScheduler that will invoke
the scheduled methods, or a ScheduledExecutorService
to be wrapped as a TaskScheduler.

setEmbeddedValueResolver in interface EmbeddedValueResolverAwarepublic void setApplicationContext(ApplicationContext applicationContext)
ApplicationContextAwareInvoked after population of normal bean properties but before an init callback such
as InitializingBean.afterPropertiesSet()
or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader),
ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and
MessageSourceAware, if applicable.

OrderedNormally starting with 0, with Integer.MAX_VALUE
indicating the greatest value. Same order values will result
in arbitrary positions for the affected objects.
Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

The returned bean instance may be a wrapper around the original.
In case of a FactoryBean, this callback will be invoked for both the FactoryBean
instance and the objects created by the FactoryBean (as of Spring 2.0). The
post-processor can decide whether to apply to either the FactoryBean or created
objects or both through corresponding bean instanceof FactoryBean checks.
This callback will also be invoked after a short-circuiting triggered by a
InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class>, java.lang.String) method,
in contrast to all other BeanPostProcessor callbacks.
