我被要求修改一个用 Java EE+Spring+Hibernate 构建的 Web 应用程序，以通过 Spring Security 提供安全性。
我以前没有使用过 Spring Security，我已经阅读了文档，但我没有看到使它工作的正确方法。
我们有一个登录页面，其中嵌入了另一个页面，该页面具有实际的登录表单，该表单调用另一个 Web 应用程序的登录操作，并使用登录结果调用我们应用程序的一个方法。（嵌入的登录页面是处理登录的“外部”Web 应用程序的一部分）。
我不明白我应该如何配置 Spring Security。我想这是一个预身份验证场景，但我不知道我应该如何让它工作。
这是我的 security-context.xml
