        Object loginUserName = ActionContext.getContext().getSession().get("id");  
        if(null == loginUserName){  
           return "goLogin.action";  // 这里返回用户登录页面视图  
        }  
        return invoker.invoke();  
    }  

}  

最后结果为 Could not find action or result
No result defined for action com.xlb.action.KaikeAction and result goLogin.action
