Package org.springframework.web.context.support

Class ServletContextScope

java.lang.Object
org.springframework.web.context.support.ServletContextScope
All Implemented Interfaces:
org.springframework.beans.factory.config.Scope, org.springframework.beans.factory.DisposableBean
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".
