public class ServletContextScope extends Object implements org.springframework.beans.factory.config.Scope, org.springframework.beans.factory.DisposableBean
Scope
wrapper for a ServletContext, i.e. for global web application attributes.
This differs from traditional Spring singletons in that it exposes attributes in the ServletContext. Those attributes will get destroyed whenever the entire application shuts down, which might be earlier or later than the shutdown of the containing Spring ApplicationContext.
The associated destruction mechanism relies on a
ContextCleanupListener
being registered in
web.xml
. Note that ContextLoaderListener
includes ContextCleanupListener's functionality.
This scope is registered as default scope with key
"application"
.
