## Class SpringObjectFactory

- java.lang.Object
- - com.opensymphony.xwork2.ObjectFactory
  - - com.opensymphony.xwork2.spring.SpringObjectFactory

- All Implemented Interfaces:
    Serializable, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware
  Direct Known Subclasses:
    SpringProxyableObjectFactory

      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.
