public class ScheduledAnnotationBeanPostProcessor extends Object implements BeanPostProcessor, Ordered, EmbeddedValueResolverAware, BeanFactoryAware, SmartInitializingSingleton, DisposableBean
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 the @EnableScheduling javadocs for complete usage details.

void |
afterSingletonsInstantiated()
Invoked right at the end of the singleton pre-instantiation phase,
with a guarantee that all regular singleton beans have been created
already.
|
void |
destroy()
Invoked by a BeanFactory on destruction of a singleton.

getOrder()
Return the order value of this object, with a
higher value meaning greater in terms of sorting.

postProcessAfterInitialization(Object bean,

Apply this BeanPostProcessor to the given new bean instance after any bean
initialization callbacks (like InitializingBean's
afterPropertiesSet
or a custom init-method). |

setBeanFactory(BeanFactory beanFactory)
Making a
BeanFactory available is optional; if not set,
SchedulingConfigurer beans won't get autodetected and
a scheduler has to be explicitly configured. |
void |
setEmbeddedValueResolver(StringValueResolver resolver)
Set the StringValueResolver to use for resolving embedded definition values.
|
void |
setScheduler(Object scheduler)
Set the
TaskScheduler that will invoke
the scheduled methods, or a ScheduledExecutorService
to be wrapped as a TaskScheduler. |

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).

lazily initialized on demand after BeanFactory bootstrap,
and not for any other bean scope either. Carefully use it for beans
with the intended bootstrap semantics only.

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.
