GWT - spring security - 缓存问题
我有一个由 Spring Security 保护的 GWT 应用程序。我有一个为应用程序提供服务的 Main.html 和用于登录的 Login.html。在大多数情况下，每次都一切正常。但有时重新启动我的应用程序后，我仍然可以访问 Main.html - 尽管页面上的大多数小部件都无法使用。我可以看到控制台中的 Login.html 的 HTML 作为异常被打印。刷新后，我会进入登录页面。有人遇到过类似的问题吗？这是某种缓存问题吗？如何避免这种情况？
I have a GWT application which is secured by Spring Security. I have a Main.html which serves the application and Login.html for login. For most part everything works fine everytime. But sometimes after restarting my application I can still access Main.html - although most of the widgets on the page are unusable. I can see the Login.html's HTML in the console being printed as exception. On refreshing, it takes me to login page. Has anyone ran into similar issue? Is this some kind of caching issue? How can this be avoided?

在您的情况下，您的引导文件似乎正在被缓存，因此正在加载应用程序的错误版本。
您必须确保您的引导文件（名为
nocache的文件）永远不会被缓存。请参阅此处了解更多详细信息。您可以使用 Firebug 并查看脚本的 HTTP 请求来检查引导文件是否已缓存。您可以检查两件事：
.cache.html .nocache.文件的响应类型不是 304 左右。It seems that in your case your bootstrap file is beining cached and thus a wrong version of your app is being loaded.
You have to make sure that your bootstrap file (the one which is named
nocache) is never cached. See here for more details.You can check if your bootstrap file is cached by using Firebug and looking at the HTTP requests for your scripts. You can check two things:
<md5>.cache.htmlare loaded (compare it to the ones in your gwt output folder)..nocache.file is not 304 or so.在我的 Main.html 顶部添加元标记 - 帮助我暂时解决了我的问题。
