public interface ApplicationEventMulticaster
ApplicationListener objects, and publish events to them.
An ApplicationEventPublisher, typically
a Spring ApplicationContext, can use an
ApplicationEventMulticaster as a delegate for actually publishing events.
| Modifier and Type | Method and Description |
|---|---|
void |
addApplicationListener(ApplicationListener<?> listener)
Add a listener to be notified of all events.
|
void |
addApplicationListenerBean(java.lang.String listenerBeanName)
Add a listener bean to be notified of all events.
|
void |
multicastEvent(ApplicationEvent event)
Multicast the given application event to appropriate listeners.
|
void |
multicastEvent(ApplicationEvent event,
org.springframework.core.ResolvableType eventType)
Multicast the given application event to appropriate listeners.
|
void |
removeAllListeners()
Remove all listeners registered with this multicaster.
|
void |
removeApplicationListener(ApplicationListener<?> listener)
Remove a listener from the notification list.
|
void |
removeApplicationListenerBean(java.lang.String listenerBeanName)
Remove a listener bean from the notification list.

void addApplicationListener(ApplicationListener<?> listener)
listener - the listener to addvoid addApplicationListenerBean(java.lang.String listenerBeanName)
listenerBeanName - the name of the listener bean to addvoid removeApplicationListener(ApplicationListener<?> listener)
listener - the listener to removevoid removeApplicationListenerBean(java.lang.String listenerBeanName)
listenerBeanName - the name of the listener bean to addvoid removeAllListeners()
After a remove call, the multicaster will perform no action on event notification until new listeners are being registered.
void multicastEvent(ApplicationEvent event)
Consider using multicastEvent(ApplicationEvent, ResolvableType)
if possible as it provides a better support for generics-based events.
event - the event to multicastvoid multicastEvent(ApplicationEvent event, org.springframework.core.ResolvableType eventType)
If the eventType is null, a default type is built
based on the event instance.
event - the event to multicasteventType - the type of event (can be null)
