The strategy for autowiring the beans can be configured by setting the parameter on the interceptor. Actions that need access to the
ActionContext
can implements the ApplicationContextAware
interface. The context will also be placed on
the action context under the APPLICATION_CONTEXT attribute.Modifier and Type | Field and Description |

the servlet context. The configuration is done the first time here instead of in init() since the
ActionContext
is not available during Interceptor
initialization.

TODO Should this check to see if the SpringObjectFactory
has already been configured
instead of instantiating a new one? Or is there a good reason for the interceptor to have it's own
factory?intercept
