程序包 cn.taketoday.web.servlet.support

类 ServletContextAttributeFactoryBean

java.lang.Object
cn.taketoday.web.servlet.support.ServletContextAttributeFactoryBean
所有已实现的接口:
cn.taketoday.beans.factory.Aware, cn.taketoday.beans.factory.FactoryBean<Object>, ServletContextAware
public class ServletContextAttributeFactoryBean extends Object implements cn.taketoday.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 Framework bean instance.

Intended to link in ServletContext attributes that exist before the startup of the Framework application context. Typically, such attributes will have been put there by third-party web frameworks. In a purely Framework-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 an "#{contextAttributes.myKey}" expression to access a specific attribute by name.
