尝试设置一个具有基本 CAS 保护的简单 Grails 应用程序。
首先，我很难说出 cas-plugin 与 spring-security-core 和 spring-security-cas 之间的区别......我什么时候使用一个与另一个？
在我的测试中，我配置了以下内容：
在 BuildConfig.groovy 中：
plugins {
...
...
compile ":spring-security-core:1.2.7.3"
compile ":spring-security-cas:1.0.5"
}
在 Config.groovy ...我不知道我需要什么。不同的文档引用不同的值，但这是我到目前为止所得到的：
grails.plugins.springsecurity.providerNames = ['casAuthenticationProvider']
grails.plugins.springsecurity.rejectIfNoRule = true
grails.plugins.springsecurity.securityConfigType = "InterceptUrlMap"
grails.plugins.springsecurity.interceptUrlMap = [
'/js/**': ['IS_AUTHENTICATED_ANONYMOUSLY'],
'/css/**': ['IS_AUTHENTICATED_ANONYMOUSLY'],
'/images/**': ['IS_AUTHENTICATED_ANONYMOUSLY'],
'/login/**': ['IS_AUTHENTICATED_ANONYMOUSLY'],
'/logout/**': ['IS_AUTHENTICATED_ANONYMOUSLY'],
'/**': ['IS_AUTHENTICATED_FULLY']
]
grails.plugins.springsecurity.cas.loginUri = '/login'
grails.plugins.springsecurity.cas.serviceUrl = 'http://cas2.mydomain.com:8085/' + appName + '/j_spring_cas_security_check'
grails.plugins.springsecurity.cas.serverUrlPrefix = 'https://cas2.mydomain.com:8443/cas'
grails.plugins.springsecurity.cas.proxyCallbackUrl = 'http://cas2.mydomain.com:8085/' + appName + '/secure/receptor'
grails.plugins.springsecurity.cas.proxyReceptorUrl = '/secure/receptor'
grails.plugins.springsecurity.logout.afterLogoutUrl = 'https://cas2.mydomain.com:8443/cas/logout?url=http://cas2.mydomain.com:8085/' + appName + '/'
现在，当我浏览到我的应用程序时，我被转发到 CAS 登录页面......输入凭据后，我得到一个浏览器错误页面：
The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
和 cas.log 说：

这一点：

似乎是问题所在...我的凭据很好，因此配置中似乎仍然缺少某些东西...任何想法...？
更新：
将应用程序置于 SSL 下，并到 Config.groovy 中，向 interceptUrlMap 添加：
'/secure/receptor': ['IS_AUTHENTICATED_ANONYMOUSLY'],
现在 cas.log 显示了与我之前得到的看起来相似的循环（在 cas 和应用程序之间来回），除了没有错误......最终它停止并且浏览器再次显示：
