java - Spring阻止用户通过浏览器和ajax访问url

Question

我在使用 Springs 安全配置时遇到了问题。我在下面分享我的代码。

我的问题是我想要 /user* url 和 /admin* url 应该只在用户登录到我的应用程序时访问，我的应用程序有主要的 ajax调用，所以我不希望任何用户在未登录的情况下访问 /user* URL。但是当我尝试在网络浏览器中键入 URL 时，我什至没有被重定向到登录页面，而是进入了在 URL 中输入的页面。

所以任何人都可以帮我解决这个问题。

Answer 1

有两个问题:

首先，您必须更正地址模式:如 user/**

其次，如果您对安全资源进行了静态调用，则可能会发生这种情况。
检查 Firebug 。您会看到一个 302 重定向 作为对您请求的响应。在这种情况下，您最好不要使用重定向，而是给出一个 403 access denied 响应并在您的 ajax 框架中手动处理它。
