SmartApplicationListener (Spring Framework 5.2.12.RELEASE API)

所有超级接口:
ApplicationListener<ApplicationEvent>, EventListener, Ordered
所有已知实现类:
DefaultSimpUserRegistry, GenericApplicationListenerAdapter, MultiServerUserRegistry, SourceFilteringListener
```
public interface SmartApplicationListener
extends ApplicationListener<ApplicationEvent>, Ordered
```
Extended variant of the standard ApplicationListener interface, exposing further metadata such as the supported event and source type.
For full introspection of generic event types, consider implementing the GenericApplicationListener interface instead.
从以下版本开始:
3.0

- 方法详细资料
  - supportsEventType
```
boolean supportsEventType(Class<? extends ApplicationEvent> eventType)
```
    Determine whether this listener actually supports the given event type.
    参数:
    eventType - the event type (never null)
  - supportsSourceType
```
default boolean supportsSourceType(@Nullable
                                   Class<?> sourceType)
```
    Determine whether this listener actually supports the given source type.
    The default implementation always returns true.
    参数:
    sourceType - the source type, or null if no source
  - getOrder
```
default int getOrder()
```
    Determine this listener's order in a set of listeners for the same event.
    The default implementation returns Ordered.LOWEST_PRECEDENCE.
    指定者:
    getOrder 在接口中 Ordered
    返回:
    the order value
