Class ServletContextParameterFactoryBean

java.lang.Object

org.springframework.web.context.support.ServletContextParameterFactoryBean

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.FactoryBean<String>, ServletContextAware

public class ServletContextParameterFactoryBean
extends Object
implements org.springframework.beans.factory.FactoryBean<String>, ServletContextAware

FactoryBean that retrieves a specific ServletContext init parameter (that is, a "context-param" defined in web.xml). Exposes that ServletContext init parameter when used as bean reference, effectively making it available as named Spring bean instance.

NOTE: As of Spring 3.0, you may also use the "contextParameters" default bean which is of type Map, and dereference it using an "#{contextParameters.myKey}" expression to access a specific parameter by name.

Since:

1.2.4
