类 ContextCleanupListener

java.lang.Object

cn.taketoday.web.servlet.ContextCleanupListener

所有已实现的接口:

ServletContextListener, EventListener

public class ContextCleanupListener
extends Object
implements ServletContextListener

Web application listener that cleans up remaining disposable attributes in the ServletContext, i.e. attributes which implement DisposableBean and haven't been removed before. This is typically used for destroying objects in "application" scope, for which the lifecycle implies destruction at the very end of the web application's shutdown phase.
