刚刚开始与SAML合作并遇到了各种各样的问题,其中大部分都是我解决的问题.但是,我仍然没有的是如何关闭发现,以便在访问任何受保护资源时,Spring自动重定向到IdP(我只有一个并且还将其设置为默认值).我在Springs文档中看到你可以很容易地关闭发现,但是文档似乎缺乏示例和/或细节,所以我不完全确定如何做到这一点.
到目前为止,我已经尝试将idpSelectionPath设置为空,以及使用includeDiscoveryExtension和idpDiscoveryEnabled设置为false.使用直接URL(context / saml / login？idp = IDP)确实有效,但不是一个选项,因为我要求任何受保护的URL在用户未登录时自动重定向到IdP.
以下是我的securityContext.xml文件的工作版本,因为我所做的一些更改(例如删除所有发现设置)导致浏览器出现无限循环错误.任何和所有的帮助表示赞赏.谢谢！

解决方法:
在MetadataGeneratorFilter中将idpDiscoveryEnabled属性设置为false对我有用.就像是：
<bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata.MetadataGeneratorFilter">
<constructor-arg>
<bean class="org.springframework.security.saml.metadata.MetadataGenerator">
<property name="extendedMetadata">
<bean class="org.springframework.security.saml.metadata.ExtendedMetadata">
<property name="idpDiscoveryEnabled" value="false"/>
</bean>
</property>
</bean>
</constructor-arg>
</bean>
