java.lang.Objectorg.springframework.web.context.support.ServletContextScope
public class ServletContextScope
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".
