SpringBoot中Shiro使用Pac4j內建CAS認證 Pac4j 簡介

Pac4j 簡介

Pac4j與Shiro，Spring Security一樣都是權限架構，并且提供了OAuth - SAML - CAS - OpenID Connect - HTTP - OpenID - Google App Engine - Kerberos (SPNEGO) 的認證內建。且可以和shiro,security等權限架構內建。

Pac4j CAS認證流程

代碼 關鍵部分

說明: pac4j-cas與shiro的內建是通過過濾器完成cas認證，提供相應的Pac4jRealm來與shiro內建。代碼過多就不一一列出了，詳細的請下載下傳附件，附件中代碼屏蔽了公司相關代碼。自身項目需要保持CAS與非CAS并存是以把CAS登入固定到指定路徑了。

POM

<!--cas認證 -->
        <dependency>
            <groupId>org.pac4j</groupId>
            <artifactId>pac4j-cas</artifactId>
            <version>3.8.3</version>
        </dependency>
<!-- pac4j與shiro內建-->
        <dependency>
            <groupId>io.buji</groupId>
            <artifactId>buji-pac4j</artifactId>
            <version>4.1.1</version>
        </dependency>           

JAVA配置

//Pac4jConfig.java 配置中
 @Bean
 public CasConfiguration casConfig() {
  final CasConfiguration configuration = new CasConfiguration();
  //CAS server登入位址
  configuration.setLoginUrl(casServerUrl + "/login");
  configuration.setAcceptAnyProxy(true);
  configuration.setPrefixUrl(casServerUrl + "/");
  //監控CAS服務端登出，登出後銷毀本地session實作雙向登出
  DefaultLogoutHandler logoutHandler = new DefaultLogoutHandler();
  logoutHandler.setDestroySession(true);
  configuration.setLogoutHandler(logoutHandler);
  return configuration;
 }
//ShiroConfig.java 中
//shiro 過濾器配置中增加SecurityFilter，CallbackFilter ，LogoutFilter 
 @Bean("shiroFilter")
 public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
  ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
  shiroFilterFactoryBean.setSecurityManager(securityManager);
  //擷取filters
  Map<String, Filter> filters = shiroFilterFactoryBean.getFilters();
  filters.put("authc", new MySystemFilter());
  // cas 資源認證攔截器
  SecurityFilter securityFilter = new SecurityFilter();
  securityFilter.setConfig(exPac4jConfig);
  securityFilter.setClients(clientName);
  filters.put("securityFilter", securityFilter);
  //cas 認證後回調攔截器
  CallbackFilter callbackFilter = new CallbackFilter();
  callbackFilter.setConfig(exPac4jConfig);
  filters.put("callbackFilter", callbackFilter);
  shiroFilterFactoryBean.setFilters(filters);
  // 本地登出同步登出CAS伺服器
  LogoutFilter pac4jCentralLogout = new LogoutFilter();
  pac4jCentralLogout.setConfig(exPac4jConfig);
  pac4jCentralLogout.setCentralLogout(true);
  pac4jCentralLogout.setLocalLogout(true);
  filters.put("pac4jCentralLogout", pac4jCentralLogout);
  //攔截器.
  Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
  filterChainDefinitionMap.put("/logout", "logout");
  filterChainDefinitionMap.put("/pac4jCentralLogout", "pac4jCentralLogout");
  filterChainDefinitionMap.put("/cas", "securityFilter");
  filterChainDefinitionMap.put("/callback", "callbackFilter");
  filterChainDefinitionMap.put("/**", "authc");
  shiroFilterFactoryBean.setLoginUrl("/login");
  shiroFilterFactoryBean.setSuccessUrl("index");
  shiroFilterFactoryBean.setUnauthorizedUrl("/error/403");
  shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
  return shiroFilterFactoryBean;
 }
 @Bean
 public SecurityManager securityManager() {
  DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
  securityManager.setAuthenticator(exModularRealmAuthenticator());
  List<Realm> realms = new ArrayList<>();
  realms.add(exSystemRealm());
 // casRealm繼承Pac4jRealm 與shiro的Realm使用方法相同
  realms.add(casRealm);
  securityManager.setRealms(realms);
  securityManager.setCacheManager(redisCacheManager());
 //增加pac4jSubjectFactory
  securityManager.setSubjectFactory(pac4jSubjectFactory);
  securityManager.setRememberMeManager(cookieRememberMeManager());
  securityManager.setSessionManager(sessionManager());
  return securityManager;
 }           

問題

• 預設配置不支援CAS登出本地項目退出

重寫ShiroSessionStore見ExShiroSessionStore.java
