 * <li>Calls {@link #customizeBeanFactory(DefaultListableBeanFactory)} to allow for customizing the

 * from the specified locations.</li>
 * <li>Delegates to {@link AnnotationConfigUtils} for
 * {@link AnnotationConfigUtils#registerAnnotationConfigProcessors registering}
 * annotation configuration processors.</li>
 * <li>Calls {@link #customizeContext(GenericApplicationContext)} to allow for customizing the context

 * <li>{@link ConfigurableApplicationContext#refresh Refreshes} the
