Shiro为每个getSession()创建一个新会话

Question

我在tapestry应用程序中使用shiro (1.2.0)。现在我只想把它用于会话管理。虽然默认会话管理(使用ServletContainerSessionManager)有效，但当我尝试切换到本机会话时，shiro停止跟踪它们：

public static WebSecurityManager decorateWebSecurityManager(WebSecurityManager manager) {
  if(manager instanceof TapestryRealmSecurityManager) {
    DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();
    MemorySessionDAO sessionDAO = new MemorySessionDAO();
    sessionManager.setSessionDAO(sessionDAO);
    ((TapestryRealmSecurityManager) manager).setSessionManager(sessionManager);
  }
  return null;
}

调试输出：

问题是我忘了删除@Persist注释，它默认使用会话来存储数据。这导致tapestry用它自己的值覆盖了shiro的JSESSIONID cookie。
