Package org.springframework.web.context.support

Class ServletContextAttributeFactoryBean

java.lang.Object
org.springframework.web.context.support.ServletContextAttributeFactoryBean
All Implemented Interfaces:
org.springframework.beans.factory.Aware, org.springframework.beans.factory.FactoryBean<Object>, ServletContextAware
public class ServletContextAttributeFactoryBean extends Object implements org.springframework.beans.factory.FactoryBean<Object>, ServletContextAware
FactoryBean that fetches a specific, existing ServletContext attribute. Exposes that ServletContext attribute when used as bean reference, effectively making it available as named Spring bean instance.

Intended to link in ServletContext attributes that exist before the startup of the Spring application context. Typically, such attributes will have been put there by third-party web frameworks. In a purely Spring-based web application, no such linking in of ServletContext attributes will be necessary.

NOTE: You may also use the "contextAttributes" default bean, which is of type Map, and dereference it using a "#{contextAttributes.myKey}" expression to access a specific attribute by name.

1.1.4
