ParentContextCloserApplicationListener (Spring Boot API)

java.lang.Object
- org.springframework.boot.builder.ParentContextCloserApplicationListener

所有已实现的接口:
EventListener, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener<ParentContextApplicationContextInitializer.ParentContextAvailableEvent>, org.springframework.core.Ordered
```
public class ParentContextCloserApplicationListener
extends Object
implements org.springframework.context.ApplicationListener<ParentContextApplicationContextInitializer.ParentContextAvailableEvent>, org.springframework.context.ApplicationContextAware, org.springframework.core.Ordered
```
Listener that closes the application context if its parent is closed. It listens for refresh events and grabs the current context from there, and then listens for closed events and propagates it down the hierarchy.

  - setApplicationContext
```
public void setApplicationContext(org.springframework.context.ApplicationContext context)
                           throws org.springframework.beans.BeansException
```
    指定者:
    setApplicationContext 在接口中 org.springframework.context.ApplicationContextAware
    抛出:
    org.springframework.beans.BeansException
  - onApplicationEvent
```
public void onApplicationEvent(ParentContextApplicationContextInitializer.ParentContextAvailableEvent event)
```
    指定者:
    onApplicationEvent 在接口中 org.springframework.context.ApplicationListener<ParentContextApplicationContextInitializer.ParentContextAvailableEvent>
  - createContextCloserListener
```
protected ParentContextCloserApplicationListener.ContextCloserListener createContextCloserListener(org.springframework.context.ConfigurableApplicationContext child)
```
    Subclasses may override to create their own subclass of ContextCloserListener. This still enforces the use of a weak reference.
    参数:
    child - the child context
    返回:
    the ParentContextCloserApplicationListener.ContextCloserListener to use
