HttpSession 为 SPRING_SECURITY_CONTEXT 返回 null 对象

我正在尝试整合Spring Saml 库在示例 Web 应用程序中，使用 Shibboleth 作为 IDP。 我能够加载登录页面、登录并显示索引页面。

问题是，当我单击其他链接时，Web 应用程序会将我重定向到登录页面，然后 IDP 会识别我并重定向到所请求的页面（如果网络速度很快，则很难看到这一点）。就好像我没有登录 Spring 安全性。

我检查了日志，发现了这一点：

org.springframework.security.web.context.HttpSessionSecurityContextRepository - HttpSession为SPRING_SECURITY_CONTEXT返回空对象 org.springframework.security.web.context.HttpSessionSecurityContextRepository - HttpSession 中没有可用的 SecurityContext：org.apache.catalina.session.StandardSessionFacade@fde8fb。将创建一个新的。

这是 web.xml

任何想法？

谢谢 埃马努埃莱

我也遇到过同样的问题。调试后发现SecurityContext在持久化之前就被清除了。谷歌搜索后我发现了这个：https://jira.springsource.org/browse/SEC-2027迁移到 Spring Security 版本 3.1.2 为我解决了这个问题。

我希望它能帮助某人。
