我正在尝试将基本应用程序从仅使用Spring Security更改为使用CAS来启用SSO。但是我正在某个地方获得重定向循环，我无法找出问题所在。我已经做了两个其他模拟应用程序，并且CAS没有问题，因为它们正在工作。我正在使用Java配置代替从here获取的XML配置。我已经尝试了XML配置的例子，但我仍然得到相同的结果。 我的猜测是对于authenticationManager的问题，它无法从Spring Security中检测到用户。该日志至少表示一个AnonymousUser并抛出AccessDeniedException。但它适用于其他两个具有相似配置的模拟应用程序（我甚至尝试过复制它，但错误仍然存在）。我一直试图解决这个问题几天没有成功，所以任何帮助都表示赞赏。我在Windows 8上使用Tomcat 8，Spring 4.2和Ja-sig CAS 4.0.0。

EDIT2：一个非常奇怪的补充：其他示例应用程序单独使用servlet，并且正在使用spring 3.2。现在，我试图模仿原始版本复制到此示例，并尝试降级它直到它工作。问题是我不能让它工作任何@Controller注释或类似...但重定向消失了。如果我更新我的maven，并从4.2到3.2，循环就消失了。但是，如果我在4.2上，除了版本之外什么也没有改变，那就是循环！
答案 0 :(得分：2)

参考：
Migrating from Spring Security 3.x to 4.x (XML Configuration)
Migrating from Spring Security 3.x to 4.x (Java Configuration)
CasAuthenticationFilter filterProcessesUrl属性的默认值从“/ j_spring_cas_security_check”更改为“/ login / cas”。这意味着如果未显式指定filterProcessesUrl属性，则需要更新配置。例如，如果使用Spring Security 3.2.x的应用程序包含类似于以下内容的配置：
CasAuthenticationFilter filter = new CasAuthenticationFilter();
filter.setAuthenticationManager(authenticationManager);
当Spring Security 4.x：
时，需要将配置更新为类似于以下内容的内容xml config：
<bean id="casFilter"
class="org.springframework.security.cas.web.CasAuthenticationFilter">
<b:property name="authenticationManager" ref="authenticationManager"/>
<b:property name="filterProcessesUrl" value="/j_spring_cas_security_check"/>
</bean>
java config：
CasAuthenticationFilter filter = new CasAuthenticationFilter();
filter.setFilterProcessesUrl("/j_spring_cas_security_check");
filter.setAuthenticationManager(authenticationManager);
或者，可以更新ServiceProperties以使用新的默认值：
xml config：
<bean id="serviceProperties"
class="org.springframework.security.cas.ServiceProperties">
<property name="service"
value="https://example.com/cas-sample/login/cas"/>
</bean>
java config：
ServiceProperties properties = new ServiceProperties();
properties.setService("https://example.com/cas-sample/login/cas");
答案 1 :(得分：2)
自Spring Security 4.x起，CAS的端点从/j_spring_cas_security_check更改为/login/cas（参见https://stackoverflow.com/a/35136587/3585320）
答案 2 :(得分：1)
CAS服务器已将服务票证（ticket参数）返回到 j_spring_cas_security_check 网址。它应该工作。在org.jasig.cas包上启用DEBUG日志以了解CAS客户端中发生的情况：服务票证验证是否成功？
答案 3 :(得分：0)
因此，它的“答案”只是将Spring Security从4.0.2降级到3.2.8。然后我只需要通过注释spring-security-xml来再次从XML模板更改为Java配置：
<param-value>
/WEB-INF/spring-context.xml
<!-- /WEB-INF/spring-security.xml -->
</param-value>
不确定这是否是“实际”答案，因为我不知道是否存在Spring Security 4的特定配置使其工作与3.2不同，但是因为我使用的所有Spring功能都是4.2只是春天，他们不需要降级工作。
答案 4 :(得分：0)
serviceProperties.setAuthenticateAllArtifacts(true);
答案 5 :(得分：0)
在我的情况下，此循环是由于Apache内部的错误重写规则所致。 /login/cas路径已更改为/secured/cas，再次进入安全的URL，从而调用了CAS登录页面。
