class ApplicationListenerDetector extends java.lang.Object implements DestructionAwareBeanPostProcessor, MergedBeanDefinitionPostProcessor
BeanPostProcessor
that detects beans which implement the ApplicationListener
interface. This catches beans that can't reliably be detected by getBeanNamesForType
and related operations which only work against top-level beans.
With standard Java serialization, this post-processor won't get serialized as part of
DisposableBeanAdapter
to begin with. However, with alternative serialization
mechanisms, DisposableBeanAdapter.writeReplace
might not get used at all, so we
defensively mark this post-processor's field state as transient
.

afterPropertiesSet
or a custom init-method). The bean will already be populated with property 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.
The default implementation returns the given bean
as-is.

DestructionAwareBeanPostProcessor
Like DisposableBean's destroy
and a custom destroy method, this
callback will only apply to beans which the container fully manages the
lifecycle for. This is usually the case for singletons and scoped beans.

The default implementation returns true
. If a pre-5 implementation
of DestructionAwareBeanPostProcessor
does not provide a concrete
implementation of this method, Spring silently assumes true
as well.
