方式一 屢次登陸方式
- MVC Controller 的 sso 方法
@RequestMapping(value = "ssoLogin.do") public String sso(String userName, String password,HttpServletRequest request, HttpServletResponse response) { AuthUser user = userDao.getUserByname(userName); UsernamePasswordToken token = new UsernamePasswordToken(username, password); //獲取當前的Subject Subject currentUser = SecurityUtils.getSubject(); currentUser.login(token); currentUser.getSession("true").setAttribute("userName",userName);//shrio session currentUser.getSession().setAttribute("loginName",userName);//http session return "xxx"; //頁面 }
- 調用
String path = "osdp";//request.getContextPath();//項目地址 String basePath = request.getScheme() + ":" + request.getServerName() + ":" + request.getServerPort() + path;//url String userName = UserHolder.getUserName(); String password = UserHolder.getPassword(); String data = "userName=" + userName + "&password=" + password; return "redirect:" + basePath + "/ssoLogin" + "?" + data;
方式二 自定義Token令牌
- MVC Controller 映射 sso 方法
/** * 單點登陸(如已經登陸,則直接跳轉) * @param userCode 登陸用戶編碼 * @param token 登陸令牌,令牌組成:sso密鑰+用戶名+日期,進行md5加密,舉例: * String secretKey = Global.getConfig("shiro.sso.secretKey"); * String token = Digests.md5(secretKey + userCode + DateUtils.getDate("yyyyMMdd")); * @param url 登陸成功後跳轉的url地址。 * @param relogin 是否從新登陸,須要從新登陸傳遞true * 例如:http://localhost/project/sso/{token}?url=xxx&relogin=true */ @RequestMapping(value = "sso/{userCode}/{token}") public String sso(@PathVariable String userCode, @PathVariable String token,@RequestParam(required=true) String url, String relogin, Model model) { Principal principal = SecurityUtils.getSubject().getPrincipal(); // 若是已經登陸 if(principal != null){ // 若是設置強制從新登陸,則從新登陸 if (BooleanUtils.toBoolean(relogin)){ SecurityUtils.getSubject().logout(); } // 不然,直接跳轉到目標頁 else{ return "redirect:" + Encodes.urlDecode2(url); } } // 進行單點登陸 if (token != null){ UsernamePasswordToken upt = new UsernamePasswordToken(); try { upt.setUsername(userCode); // 登陸用戶名 upt.setPassword(token.toCharArray()); // 密碼組成:sso密鑰+用戶名+日期,進行md5加密,舉例: Digests.md5(secretKey+username+20150101)) upt.setParams(upt.toString()); // 單點登陸識別參數,see: AuthorizingRealm.assertCredentialsMatch } catch (Exception ex){ if (!ex.getMessage().startsWith("msg:")){ ex = new AuthenticationException("msg:受權令牌錯誤,請聯繫管理員。"); } model.addAttribute("exception", ex); } try { SecurityUtils.getSubject().login(upt); return "redirect:" + Encodes.urlDecode2(url); } catch (AuthenticationException ae) { if (!ae.getMessage().startsWith("msg:")){ ae = new AuthenticationException("msg:受權錯誤,請檢查用戶配置,若不能解決,請聯繫管理員。"); } model.addAttribute("exception", ae); } } return "error/403"; }
- 重載org.apache.shiro.realm.AuthorizingRealm類的assertCredentialsMatch方法
/** * 認證密碼匹配調用方法 */ @Override protected void assertCredentialsMatch(AuthenticationToken authcToken, AuthenticationInfo info) throws AuthenticationException { UsernamePasswordToken token = (UsernamePasswordToken) authcToken; // 若單點登陸,則使用單點登陸受權方法。 if (token.toString().equals(token.getParams())){ // sso密鑰+用戶名+日期,進行md5加密,舉例: Digests.md5(secretKey+username+20150101)) String secretKey = Global.getConfig("shiro.sso.secretKey"); String password = Digests.md5(secretKey + token.getUsername() + DateUtils.getDate("yyyyMMdd")); if (password.equals(String.valueOf(token.getPassword()))){ return; } } super.assertCredentialsMatch(token, info); }
- 實現Shiro無狀態訪問,如經過傳遞sessionid參數便可實現會話訪問
public class SessionManager extends DefaultWebSessionManager { public SessionManager() { super(); } @Override protected Serializable getSessionId(ServletRequest request, ServletResponse response) { // 若是參數中包含「__sid」參數,則使用此sid會話。 例如:http://localhost/project?__sid=xxx&__cookie=true // 其實這裏還可使用以下參數:cookie中的session名稱:如:JSESSIONID=xxx,路徑中的 ;JESSIONID=xxx,但建議仍是使用 __sid參數。 String sid = request.getParameter("__sid"); if (StringUtils.isNotBlank(sid)) { // 是否將sid保存到cookie,瀏覽器模式下使用此參數。 if (WebUtils.isTrue(request, "__cookie")){ HttpServletRequest rq = (HttpServletRequest)request; HttpServletResponse rs = (HttpServletResponse)response; Cookie template = getSessionIdCookie(); Cookie cookie = new SimpleCookie(template); cookie.setValue(sid); cookie.saveTo(rq, rs); } // 設置當前session狀態 request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, ShiroHttpServletRequest.URL_SESSION_ID_SOURCE); // session來源與url request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, sid); request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE); return sid; }else{ return super.getSessionId(request, response); } } }
- 調用
String path = "osdp";//request.getContextPath();//項目地址 String basePath = request.getScheme() + ":" + request.getServerName() + ":" + request.getServerPort() + path;//url String userName = UserHolder.getUserName(); String secretKey = "SSO"; String token = DigestUtils.md5Hex(secretKey + userName + CommonUtil.getToday()); String data = "userName=" + userName + "&token=" + token; return "redirect:" + basePath + "/ssoLogin" + "?" + data;
注意:shiro配置放開單點請求:/sso** =anon
以上兩種方式能夠實現簡單的單點登陸,基本思想就是多個子系統登陸一遍(自定義token登陸或用戶名密碼登陸,原理同樣)。java
多點註銷
每個子項目註銷一遍:apache
final String loginName = session.getAttribute("loginName");//當前登陸賬號 new Thread(new Runnable(){ @Override public void run(){ HttpUtil.get("xxx/ssoLogout?loginName=" + loginName);//接口調用:註銷其餘項目 } }).start(); //註銷 SecurityUtils.getSubject().logout(); void ssoLogout(HttpServletRequest request, HttpServletResponse response){ String loginName = request.getParameter("loginName"); //註銷賬號 // 1.獲取當前用戶sessionId String currentUserSessionId = SecurityUtils.getSubject().getSession().getId().toString(); // 2.獲取shiro的sessionManager DefaultWebSecurityManager securityManager = (DefaultWebSecurityManager) SecurityUtils.getSecurityManager(); DefaultWebSessionManager sessionManager = (DefaultWebSessionManager)securityManager.getSessionManager(); // 3.獲取全部已登陸用戶的session列表 Collection<Session> sessions = sessionManager.getSessionDAO().getActiveSessions(); //清除session if(!CollectionUtils.isEmpty(sessions)&&sessions.size() > 1){ User user = null; for(Session session:sessions){ // 4. 獲取已登陸用戶的session的key值 SimplePrincipalCollection simplePrincipalCollection = (SimplePrincipalCollection) session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY); // 5. 獲取new SimpleAuthenticationInfo(user, pwd, this.getName())中放進去的第一個參數 user = (User) simplePrincipalCollection.getPrimaryPrincipal(); // 6. 清除當前用戶及之前登陸時保存的session會話 if (loginName.equals(user.getUserName()) && session.getId().equals(currentUserSessionId)) { sessionManager.getSessionDAO().delete(session); System.out.println("清理用戶["+loginName+"],SessionId爲["+session.getId()+"]的Session信息!"); } } } }
