Package org.apache.struts2.spring

Class SpringObjectFactory

java.lang.Object
org.apache.struts2.ObjectFactory
org.apache.struts2.spring.SpringObjectFactory
All Implemented Interfaces:
Serializable, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware
Direct Known Subclasses:
SpringProxyableObjectFactory, StrutsSpringObjectFactory
public class SpringObjectFactory extends ObjectFactory implements org.springframework.context.ApplicationContextAware

Simple implementation of the ObjectFactory that makes use of Spring's application context if one has been configured, before falling back on the default mechanism of instantiating a new class using the class name.

In order to use this class in your application, you will need to instantiate a copy of this class and set it as XWork's ObjectFactory before the xwork.xml file is parsed. In a servlet environment, this could be done using a ServletContextListener.
