Examples of org.springframework.web.context.ContextCleanupListener

org.springframework.web.context.ContextCleanupListener
Web application listener that cleans up remaining disposable attributes in the ServletContext, i.e. attributes which implement {@link 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. @author Juergen Hoeller @since 3.0 @see org.springframework.web.context.support.ServletContextScope @see ContextLoaderListener

    
    // Register the Spring Context in the ServletContext
    sc.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, ctx);


    // Manages the lifecycle
    sc.addListener(new ContextCleanupListener());
    
    // Filters
    sc.addFilter("OpenEntityInViewFilter", OpenEntityManagerInViewFilter.class).addMappingForUrlPatterns(null, true, "/*"); // Used for JPA, to ensure there's an EntityManager available
    
    log.debug("${artifactId} initialized.");
