我有一个spring安全小项目的分支。您可以在这里看到我所应用的更改:https://github.com/troyhart/spring-security-saml/commits/nwri-sample_simple.
SP urn:troyhart:nwri在单点登录圈中注册。如果您有一个SSO Circle登录，您可以启动应用程序并测试SP发起的SSO是否有效。但是，我无法使IDP发起的SSO工作。我得到以下异常:

奇怪的是，异常表明样例应用程序认为IDP EntityID是http://idp.ssocircle.com，但SSO Circle的实际EntityID是https://idp.ssocircle.com。
有人知道这里发生了什么吗?奇怪的是，我已经测试过IDP启动确实有效，但在某些时候它停止工作，现在每次都失败，并给出异常。请帮助!
问题是快速入门指南在SSO Circle的文档idp发起的SSO URL中引用了已弃用的metaAlias。新值为"/publicidp"。
