/**
 * Add this annotation to an {@code @Configuration} class to expose the
 * SessionRepositoryFilter as a bean named "springSessionRepositoryFilter" and
 * backed by a user provided implementation of {@link SessionRepository}. In
 * order to leverage the annotation, a single {@link SessionRepository} bean
 * must be provided. For example:
 *
 * <pre>
 * <code>
 * {@literal @Configuration}
 * {@literal @EnableSpringHttpSession}
 * public class SpringHttpSessionConfig {
 *
 *     {@literal @Bean}
 *     public MapSessionRepository sessionRepository() {
 *         return new MapSessionRepository();
 *     }
 *
 * }
 * </code>
 * </pre>
 *
 * <p>
 * It is important to note that no infrastructure for session expirations is
 * configured for you out of the box. This is because things like session
 * expiration are highly implementation dependent. This means if you require
 * cleaning up expired sessions, you are responsible for cleaning up the expired
 * sessions.
 * </p>
 *
 * <p>
 * The following is provided for you with the base configuration:
 * </p>
 *
 * <ul>
 * <li>SessionRepositoryFilter - is responsible for wrapping the
 * HttpServletRequest with an implementation of HttpSession that is backed by a
 * SessionRepository</li>
 * <li>SessionEventHttpSessionListenerAdapter - is responsible for translating
 * Spring Session events into HttpSessionEvent. In order for it to work, the
 * implementation of SessionRepository you provide must support
 * {@link SessionCreatedEvent} and {@link SessionDestroyedEvent}.</li>
 * <li>
