Session集中管理方案中，如何设置与之前写的SessionListener兼容，使之能触发？

/**
 * Declared in web.xml as
 *
 * <pre>
 * &lt;listener&gt;
 *     &lt;listener-class&gt;org.springframework.security.web.session.HttpSessionEventPublisher&lt;/listener-class&gt;
 * &lt;/listener&gt;
 * </pre>
 *
 * Publishes <code>HttpSessionApplicationEvent</code>s to the Spring Root
 * WebApplicationContext. Maps javax.servlet.http.HttpSessionListener.sessionCreated() to
 * {@link HttpSessionCreatedEvent}. Maps
 * javax.servlet.http.HttpSessionListener.sessionDestroyed() to
 * {@link HttpSessionDestroyedEvent}.

public class HttpSessionEventPublisher implements HttpSessionListener {

关注下Spring的这个类看看，我觉得方向应该是这个，通过这个类把Event传到Context，然后在Context上注册Listener，具体细节去翻翻源代码看看
