Class ContextCleanupListener
java.lang.Object
org.springframework.web.context.ContextCleanupListener
- All Implemented Interfaces:
- java.util.EventListener, javax.servlet.ServletContextListener
public class ContextCleanupListener
- extends java.lang.Object
- implements javax.servlet.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.
