最近公司接了一个项目，甲方需要集成到金智系统登录,他们的数据在那边，然后需要使用cas来完成，网上了解了一下 大概就是通过cas系统来拦截请求验票，重定向到指定url登录以后再调回来处理请求接口
大致流程如下
1. 在Maven项目中引入CAS（Central Authentication Service）客户端核心库。CAS是一个开源的企业级单点登录解决方案，用于实现Web应用程序的集中认证和授权。
1 | org.jasig.cas.clientcas-client-core3.5.0 |
2.yml配置cas
3.cas配置类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 | @Configuration@Slf4j@ConditionalOnProperty(value = "cas.loginType", havingValue = "cas")public class CasFilterConfig { /** * 需要走cas拦截的地址（/* 所有地址都拦截） */ @Value("${cas.urlPattern:/*}") private String filterUrl; /** * 默认的cas地址，防止通过 配置信息获取不到 */ @Value("${cas.server-url-prefix}") private String casServerUrl; /** * 应用访问地址（这个地址需要在cas服务端进行配置） */ @Value("${cas.authentication-url}") private String authenticationUrl; /** * 应用访问地址（这个地址需要在cas服务端进行配置） */ @Value("${cas.client-host-url}") private String appServerUrl; @Bean public ServletListenerRegistrationBean servletListenerRegistrationBean() { log.info(" n cas 单点登录配置 n appServerUrl = " + appServerUrl + "n casServerUrl = " + casServerUrl); log.info(" servletListenerRegistrationBean "); ServletListenerRegistrationBean listenerRegistrationBean = new ServletListenerRegistrationBean(); listenerRegistrationBean.setListener(new SingleSignOutHttpSessionListener()); listenerRegistrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE); return listenerRegistrationBean; } /** * 单点登录退出 * * @return */ @Bean public FilterRegistrationBean singleSignOutFilter() { log.info(" servletListenerRegistrationBean "); FilterRegistrationBean registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(new SingleSignOutFilter()); registrationBean.addUrlPatterns(filterUrl); registrationBean.addInitParameter("casServerUrlPrefix", casServerUrl); registrationBean.setName("CAS Single Sign Out Filter"); registrationBean.setOrder(1); return registrationBean; } /** * 单点登录认证 * * @return */ @Bean public FilterRegistrationBean AuthenticationFilter() { log.info(" AuthenticationFilter "); FilterRegistrationBean registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(new AuthenticationFilter()); registrationBean.addUrlPatterns(filterUrl); registrationBean.setName("CAS Filter"); registrationBean.addInitParameter("casServerLoginUrl", casServerUrl); registrationBean.addInitParameter("serverName", appServerUrl); registrationBean.setOrder(1); return registrationBean; } /** * 单点登录校验 * * @return */ @Bean public FilterRegistrationBean Cas30ProxyReceivingTicketValidationFilter() { log.info(" Cas30ProxyReceivingTicketValidationFilter "); FilterRegistrationBean registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(new Cas30ProxyReceivingTicketValidationFilter()); registrationBean.addUrlPatterns(filterUrl); registrationBean.setName("CAS Validation Filter"); registrationBean.addInitParameter("casServerUrlPrefix", authenticationUrl); registrationBean.addInitParameter("serverName", appServerUrl); registrationBean.setOrder(1); return registrationBean; } /** * 单点登录请求包装 * * @return */ @Bean public FilterRegistrationBean httpServletRequestWrapperFilter() { log.info(" httpServletRequestWrapperFilter "); FilterRegistrationBean registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(new HttpServletRequestWrapperFilter()); registrationBean.addUrlPatterns(filterUrl); registrationBean.setName("CAS HttpServletRequest Wrapper Filter"); registrationBean.setOrder(1); return registrationBean; }} |
4.对接cas统一认证后接受的用户信息对象
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 | /** * @Author: * @Date: * @Description: 使用cas对接封装的cas返回的用户信息的对象 */public class CasUtil { private static final Logger LOGGER = LoggerFactory.getLogger(CasUtil.class); /** * cas client 默认的session key */ public final static String CAS = "_const_cas_assertion_"; /** * 封装CasUserInfo * * @param request * @return */ public static CasUserInfo getCasUserInfoFromCas(HttpServletRequest request) { Object object = request.getSession().getAttribute(CAS); if (null == object) { return null; } Assertion assertion = (Assertion) object; return buildCasUserInfoByCas(assertion); } /** * 构建CasUserInfo * * @param assertion * @return */ private static CasUserInfo buildCasUserInfoByCas(Assertion assertion) { if (null == assertion) { LOGGER.error(" Cas没有获取到用户 "); return null; } CasUserInfo casUserInfo = new CasUserInfo(); String userName = assertion.getPrincipal().getName(); LOGGER.info(" cas对接登录用户= " + userName); casUserInfo.setUserAccount(userName); //获取属性值 Map attributes = assertion.getPrincipal().getAttributes(); Object name = attributes.get("cn"); casUserInfo.setUserName(name == null ? userName : name.toString()); casUserInfo.setAttributes(attributes); return casUserInfo; } |
5.用户信息实体
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | /** * @Author: * @Date: * @Description: 返回的用户信息 */@Setter@Getterpublic class CasUserInfo { /** 用户名 */ private String userName; /** 用户 */ private String userAccount; /** 用户信息 */ private Map attributes;} |
6.验证统一认证登录后跳回来的处理
1 2 3 4 5 6 7 8 9 10 11 | /** * 统一认证成功后跳转 * * @return */@GetMapping(value = "/index")public ResponseVo index(HttpServletRequest request) { CasUserInfo userInfo = CasUtil.getCasUserInfoFromCas(request); log.info("userInfo = " + JSONObject.toJSON(userInfo)); } |
统一认证登录成功以后，回来再根据用户信息校验用户，生成对应token
7.退出
最后跳转回来的时候因为url里面带了;被拦截报错
The request was rejected because the URL contained a potentially malicious String “;”
最后在网上搜了一下相关错误
解决办法 在yml配置server加了以下配置
1 2 3 | servlet: session: tracking-modes: cookie |
