- org.springframework.context.event.SourceFilteringListener

所有已实现的接口:
EventListener, ApplicationListener<ApplicationEvent>, GenericApplicationListener, SmartApplicationListener, Ordered
```
public class SourceFilteringListener
extends Object
implements GenericApplicationListener, SmartApplicationListener
```
ApplicationListener decorator that filters events from a specified event source, invoking its delegate listener for matching ApplicationEvent objects only.
Can also be used as base class, overriding the onApplicationEventInternal(org.springframework.context.ApplicationEvent) method instead of specifying a delegate listener.
从以下版本开始:
2.0.5

  - SourceFilteringListener
```
public SourceFilteringListener(Object source,
                               ApplicationListener<?> delegate)
```
    Create a SourceFilteringListener for the given event source.
    参数:
    source - the event source that this listener filters for, only processing events from this source
    delegate - the delegate listener to invoke with event from the specified source
  - SourceFilteringListener
```
protected SourceFilteringListener(Object source)
```
    Create a SourceFilteringListener for the given event source, expecting subclasses to override the onApplicationEventInternal(org.springframework.context.ApplicationEvent) method (instead of specifying a delegate listener).
    参数:
    source - the event source that this listener filters for, only processing events from this source
- 方法详细资料
  - onApplicationEvent
```
public void onApplicationEvent(ApplicationEvent event)
```
    从接口复制的说明: ApplicationListener
    Handle an application event.
    指定者:
    onApplicationEvent 在接口中 ApplicationListener<ApplicationEvent>
    参数:
    event - the event to respond to
  - supportsEventType
```
public boolean supportsEventType(ResolvableType eventType)
```
    从接口复制的说明: GenericApplicationListener
    Determine whether this listener actually supports the given event type.
    指定者:
    supportsEventType 在接口中 GenericApplicationListener
    参数:
    eventType - the event type (never null)
  - supportsEventType
```
public boolean supportsEventType(Class<? extends ApplicationEvent> eventType)
```
    从接口复制的说明: SmartApplicationListener
    Determine whether this listener actually supports the given event type.
    指定者:
    supportsEventType 在接口中 SmartApplicationListener
    参数:
    eventType - the event type (never null)
  - supportsSourceType
```
public boolean supportsSourceType(Class<?> sourceType)
```
    从接口复制的说明: GenericApplicationListener
    Determine whether this listener actually supports the given source type.
    指定者:
    supportsSourceType 在接口中 GenericApplicationListener
    指定者:
    supportsSourceType 在接口中 SmartApplicationListener
    参数:
    sourceType - the source type, or null if no source
  - getOrder
```
public int getOrder()
```
    从接口复制的说明: Ordered
    Get the order value of this object.
    Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).
    Same order values will result in arbitrary sort positions for the affected objects.
    指定者:
    getOrder 在接口中 Ordered
    返回:
    the order value
    另请参阅:
    Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE
  - onApplicationEventInternal
```
protected void onApplicationEventInternal(ApplicationEvent event)
```
    Actually process the event, after having filtered according to the desired event source already.
    The default implementation invokes the specified delegate, if any.
    参数:
    event - the event to process (matching the specified source)
