Method Detail

contextInitialized

public void contextInitialized(ServletContextEvent servletContextEvent)

This notification occurs when the webapp is ready to process requests.

We use this hook to cleanly start up the ServletCacheAdministrator and create the application scope cache (which will consequentially initialize any listeners configured for it that implement LifecycleAware.)

As of Servlet 2.4, this is guaranteed to be called before any Servlet.init() methods.

Specified by:: contextInitialized in interface ServletContextListener

contextDestroyed

public void contextDestroyed(ServletContextEvent servletContextEvent)

This notification occurs when the servlet context is about to be shut down. We use this hook to cleanly shut down the cache.

Specified by:: contextDestroyed in interface ServletContextListener
