Spring MVC，如何让控制器处理程序处理映射处理程序之前的所有请求？
我编写了一个 Web 应用程序，其中包含勇敢的控制器和处理程序映射，所有内容都带有 Spring 3.0 和控制器注释。现在事实证明我需要简单和自定义的身份验证。我暂时不想使用ACEGI，因为我没有时间学习它。理想情况下，我希望我可以有一个例程，在每个映射处理程序之前调用，从 HttpSession 获取 userId，检查他是否已登录以及会话密钥，如果没有则重定向到登录页面。我一直在考虑拦截器...问题是您必须使用 HandlerInterceptorAdapter，它具有以下方法：
public boolean preHandle(
HttpServletRequest request,
HttpServletResponse response,
Object handler) throws Exception {
这不会让我访问与请求关联的 HttpSession。我该如何解决这个问题？
I've wrote a web app with its brave controllers and handler mapping, everything with Spring 3.0 and controller annotations. Now turns out that I need simple and custom autentication. I don't want to use ACEGI for the moment, because I've no time to learn it. I'd like ideally that I could have a routine that gets called before every mapped handler, gets from the HttpSession the userId, checks if he is logged in and the session key and if not redirects to a login page. I've been thinking about an interceptor... the problem is that you have to use HandlerInterceptorAdapter, which has the following method:
public boolean preHandle(
HttpServletRequest request,
HttpServletResponse response,
Object handler) throws Exception {
that won't let me access the HttpSession associated with the request. How do I solve this?

你确定吗？您应该能够通过
request.getSession()获取会话。Are you sure? You should be able to obtain the session through
request.getSession().
