這篇文章將為大家詳細講解有關如何在Spring Security中使用CAS,文章內容質量較高,因此小編分享給大家做個參考,希望大家閱讀完這篇文章后對相關知識有一定的了解。

配置
web.xml
<filter> <filter-name>casFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>casFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class> </listener>

#CAS服務地址 cas.url=https://cas.example.com:8443 #CAS客戶端地址,就是本應用的地址 client.url=http://localhost:8080
分析
在applicationContext-security.xml中的security filter chain中,我們使用了5個filter,分別是:singleSignOutFilter、cas20ProxyReceivingTicketValidationFilter、authenticationFilter、httpServletRequestWrapperFilter、assertionThreadLocalFilter。
為什么不用spring-security-cas
spring-security-cas
在spring-security-cas中負責ticket validator filter使用的是org.springframework.security.cas.authentication.CasAuthenticationProvider。
private CasAuthenticationToken authenticateNow(final Authentication authentication) throws AuthenticationException {
try {
final Assertion assertion = this.ticketValidator.validate(authentication.getCredentials().toString(), getServiceUrl(authentication));
...在構建validator的validator方法的第二個參數時
private String getServiceUrl(Authentication authentication) {
String serviceUrl;
if(authentication.getDetails() instanceof ServiceAuthenticationDetails) {
serviceUrl = ((ServiceAuthenticationDetails)authentication.getDetails()).getServiceUrl();
}else if(serviceProperties == null){
throw new IllegalStateException("serviceProperties cannot be null unless Authentication.getDetails() implements ServiceAuthenticationDetails.");
}else if(serviceProperties.getService() == null){
throw new IllegalStateException("serviceProperties.getService() cannot be null unless Authentication.getDetails() implements ServiceAuthenticationDetails.");
}else {
serviceUrl = serviceProperties.getService();
}
if(logger.isDebugEnabled()) {
logger.debug("serviceUrl = "+serviceUrl);
}
return serviceUrl;
