- org.springframework.context.event.ApplicationListenerMethodAdapter

所有已实现的接口:
EventListener, ApplicationListener<ApplicationEvent>, GenericApplicationListener, Ordered
```
public class ApplicationListenerMethodAdapter
extends Object
implements GenericApplicationListener
```
GenericApplicationListener adapter that delegates the processing of an event to an EventListener annotated method.
Delegates to processEvent(ApplicationEvent) to give subclasses a chance to deviate from the default. Unwraps the content of a PayloadApplicationEvent if necessary to allow a method declaration to define any arbitrary event type. If a condition is defined, it is evaluated prior to invoking the underlying method.

  - 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)
  - supportsSourceType
```
public boolean supportsSourceType(@Nullable
                                  Class<?> sourceType)
```
    从接口复制的说明: GenericApplicationListener
    Determine whether this listener actually supports the given source type.
    The default implementation always returns true.
    指定者:
    supportsSourceType 在接口中 GenericApplicationListener
    参数:
    sourceType - the source type, or null if no source
  - getOrder
```
public int getOrder()
```
    从接口复制的说明: GenericApplicationListener
    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 GenericApplicationListener
    指定者:
    getOrder 在接口中 Ordered
    返回:
    the order value
    另请参阅:
    Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE
  - processEvent
```
public void processEvent(ApplicationEvent event)
```
    Process the specified ApplicationEvent, checking if the condition matches and handling a non-null result, if any.
  - resolveArguments
```
@Nullable
protected Object[] resolveArguments(ApplicationEvent event)
```
    Resolve the method arguments to use for the specified ApplicationEvent.
    These arguments will be used to invoke the method handled by this instance. Can return null to indicate that no suitable arguments could be resolved and therefore the method should not be invoked at all for the specified event.
  - handleResult
```
protected void handleResult(Object result)
```
  - handleAsyncError
```
protected void handleAsyncError(Throwable t)
```
  - doInvoke
```
@Nullable
protected Object doInvoke(Object... args)
```
    Invoke the event listener method with the given argument values.
  - getTargetBean
```
protected Object getTargetBean()
```
    Return the target bean instance to use.
  - getCondition
```
@Nullable
protected String getCondition()
```
    Return the condition to use.
    Matches the condition attribute of the EventListener annotation or any matching attribute on a composed annotation that is meta-annotated with @EventListener.
  - getDetailedErrorMessage
```
protected String getDetailedErrorMessage(Object bean,
                                         String message)
```
    Add additional details such as the bean type and method signature to the given error message.
    参数:
    message - error message to append the HandlerMethod details to
  - toString
```
public String toString()
```
    覆盖:
    toString 在类中 Object
