所有已实现的接口:
Aware, BeanClassLoaderAware, BeanFactoryAware, ApplicationEventMulticaster
直接已知子类:
SimpleApplicationEventMulticaster
```
public abstract class AbstractApplicationEventMulticaster
extends Object
implements ApplicationEventMulticaster, BeanClassLoaderAware, BeanFactoryAware
```
Abstract implementation of the ApplicationEventMulticaster interface, providing the basic listener registration facility.
Doesn't permit multiple instances of the same listener by default, as it keeps listeners in a linked Set. The collection class used to hold ApplicationListener objects can be overridden through the "collectionClass" bean property.
Implementing ApplicationEventMulticaster's actual ApplicationEventMulticaster.multicastEvent(org.springframework.context.ApplicationEvent) method is left to subclasses. SimpleApplicationEventMulticaster simply multicasts all events to all registered listeners, invoking them in the calling thread. Alternative implementations could be more sophisticated in those respects.
从以下版本开始:

  - setBeanClassLoader
```
public void setBeanClassLoader(ClassLoader classLoader)
```
    从接口复制的说明: BeanClassLoaderAware
    Callback that supplies the bean class loader to a bean instance.
    Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean'sInitializingBean.afterPropertiesSet() method or a custom init-method.
    指定者:
    setBeanClassLoader 在接口中 BeanClassLoaderAware
    参数:
    classLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()
  - setBeanFactory
```
public void setBeanFactory(BeanFactory beanFactory)
```
    从接口复制的说明: BeanFactoryAware
    Callback that supplies the owning factory to a bean instance.
    Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.
    指定者:
    setBeanFactory 在接口中 BeanFactoryAware
    参数:
    beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

    BeanInitializationException
  - addApplicationListener

public void addApplicationListener(ApplicationListener<?> listener)
```
    从接口复制的说明: ApplicationEventMulticaster
    Add a listener to be notified of all events.
    指定者:
    addApplicationListener 在接口中 ApplicationEventMulticaster
    参数:
    listener - the listener to add
  - addApplicationListenerBean
```
public void addApplicationListenerBean(String listenerBeanName)
```
    从接口复制的说明: ApplicationEventMulticaster
    Add a listener bean to be notified of all events.
    指定者:
    addApplicationListenerBean 在接口中 ApplicationEventMulticaster
    参数:
    listenerBeanName - the name of the listener bean to add
  - removeApplicationListener
```
public void removeApplicationListener(ApplicationListener<?> listener)
```
    从接口复制的说明: ApplicationEventMulticaster
    Remove a listener from the notification list.
    指定者:
    removeApplicationListener 在接口中 ApplicationEventMulticaster
    参数:
    listener - the listener to remove
  - removeApplicationListenerBean
```
public void removeApplicationListenerBean(String listenerBeanName)
```
    从接口复制的说明: ApplicationEventMulticaster
    Remove a listener bean from the notification list.
    指定者:
    removeApplicationListenerBean 在接口中 ApplicationEventMulticaster
    参数:
    listenerBeanName - the name of the listener bean to add
  - removeAllListeners
```
public void removeAllListeners()
```
    从接口复制的说明: ApplicationEventMulticaster
    Remove all listeners registered with this multicaster.
    After a remove call, the multicaster will perform no action on event notification until new listeners are being registered.
    指定者:
    removeAllListeners 在接口中 ApplicationEventMulticaster
  - getApplicationListeners
```
protected Collection<ApplicationListener<?>> getApplicationListeners()
```
    Return a Collection containing all ApplicationListeners.
    返回:
    a Collection of ApplicationListeners
    另请参阅:
    ApplicationListener
  - getApplicationListeners
```
protected Collection<ApplicationListener<?>> getApplicationListeners(ApplicationEvent event,
                                                                     ResolvableType eventType)
```
    Return a Collection of ApplicationListeners matching the given event type. Non-matching listeners get excluded early.
    参数:
    event - the event to be propagated. Allows for excluding non-matching listeners early, based on cached matching information.
    eventType - the event type
    返回:
    a Collection of ApplicationListeners
    另请参阅:
    ApplicationListener
  - supportsEvent
```
protected boolean supportsEvent(Class<?> listenerType,
                                ResolvableType eventType)
```
    Filter a listener early through checking its generically declared event type before trying to instantiate it.
    If this method returns true for a given listener as a first pass, the listener instance will get retrieved and fully evaluated through a supportsEvent(ApplicationListener, ResolvableType, Class) call afterwards.
    参数:
    listenerType - the listener's type as determined by the BeanFactory
    eventType - the event type to check
    返回:
    whether the given listener should be included in the candidates for the given event type
  - supportsEvent
```
protected boolean supportsEvent(ApplicationListener<?> listener,
                                ResolvableType eventType,
                                Class<?> sourceType)
```
    Determine whether the given listener supports the given event.
    The default implementation detects the SmartApplicationListener and GenericApplicationListener interfaces. In case of a standard ApplicationListener, a GenericApplicationListenerAdapter will be used to introspect the generically declared type of the target listener.
    参数:
    listener - the target listener to check
    eventType - the event type to check against
    sourceType - the source type to check against
    返回:
    whether the given listener should be included in the candidates for the given event type
