org.springframework.scheduling.annotation.AsyncAnnotationBeanPostProcessor
public class AsyncAnnotationBeanPostProcessor
Bean post-processor that automatically applies asynchronous invocation
behavior to any bean that carries the Async annotation at class or
method-level by adding a corresponding AsyncAnnotationAdvisor to the
exposed proxy (either an existing AOP proxy or a newly generated proxy that
implements all of the target's interfaces).
The TaskExecutor responsible for the asynchronous execution may
be provided as well as the annotation type that indicates a method should be
invoked asynchronously. If no annotation type is specified, this post-
processor will detect both Spring's @Async annotation as well
as the EJB 3.1 javax.ejb.Asynchronous annotation.

public void setAsyncAnnotationType(Class<? extends Annotation> asyncAnnotationType)
Async annotation and the EJB 3.1
javax.ejb.Asynchronous annotation will be detected.
This setter property exists so that developers can provide their own (non-Spring-specific) annotation type to indicate that a method (or all methods of a given class) should be invoked asynchronously.
asyncAnnotationType - the desired annotation typepublic void setExecutor(Executor executor)
Executor to use when invoking methods asynchronously.
public void setBeanClassLoader(ClassLoader classLoader)
BeanClassLoaderAwareclass loader to
a bean instance.
Invoked after the population of normal bean properties but
before an initialization callback such as
InitializingBean's
InitializingBean.afterPropertiesSet()
method or a custom init-method.
setBeanClassLoader in interface BeanClassLoaderAwareclassLoader - the owning class loader; may be null in
which case a default ClassLoader must be used, for example
the ClassLoader obtained via
ClassUtils.getDefaultClassLoader()public void afterPropertiesSet()
InitializingBeanThis method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.
afterPropertiesSet in interface InitializingBeanpublic int getOrder()
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.
