The Servlet spec prohibits ServletContextListeners from being registered programatically other than from with a call to `ServletContainerInitializer.onStartup`. This restriction is not consistently enforced by the various embedded servlet containers that Boot supports: - Jetty 8 does not enforce the restriction. - Jetty 9 enforces the restriction. We were working around it be calling setExendedListenerTypes(true) on the context. - Tomcat somewhat enforces the restriction: it doesn't allow a ServletContextListener to be added once the first ServletContextListener has been called. We were using a LifecycleListener to drive the ServletContextListeners. - Undertow enforces the restriction and we were not working around it. This resulted in gh-2192 being raised. ServletListenerRegistrationBean is a ServletContextListener and is used to register listeners, including ServletContextListeners, with the servlet context. To adhere to the letter of the servlet spec this means that ServletListenerRegistrationBeans need to be called from with ServletContainerInitializer.onStartup. This commit updates all of the embedded servlet container implementations to use a ServletContainerInitializer to drive any ServletContextInitializers. This makes the lifecycle more consistent across the supported containers and allows ServletListenerRegistrationBeans to be able to register ServletContextListeners on all supported embedded containers. Fixes gh-2192 |
