Interface to be implemented by configurable web application contexts. Supported by ContextLoader and FrameworkServlet. 
Note: The setters of this interface need to be called before an invocation of the refresh method inherited from ConfigurableApplicationContext. They do not cause an initialization of the context on their own.
