Package org.springframework.web.context.support

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

1.2.4
