springmvc集成cas，并解决先后端分离状况
1.最近项目须要集成已经存在的cas系统。 可是目前已集成的系统都是jsp。而咱们项目是先后端分离开发（伪），没有分开部署。javascript
2.cas原理就不介绍了 网上例子不少。基本都是使用302重定向实现的。html
下面介绍一下本身是怎么解决先后端分离的cas集成方式。前端
springmvc集成cas配置：java

<security:intercept-url pattern="/index.html" access="hasRole('APP_USER')" />
<security:intercept-url pattern="/redirect.html" access="hasRole('APP_USER')" />//由于是伪先后端分离 这2个url拦截是为了用户直接刷新页面时触发未登陆状况跳转cas登陆页使用。 index.html是个人主页

重点讲几个配置。因为先后端分离采用json交互，而cas是302重定向。 则咱们须要改变cas入口点，不能使用默认的point。重写 CasAuthenticationEntryPoint为XXCasAuthenticationEntryPoint。jquery

如上，若是触发cas跳转则改为返回json数据 。前端判断指定状态码，而后进行对应操做。具体 看下方前端介绍。 cas-client 3.5.0版本提供了这种接口。我这里使用的是 3.2.1版本。 angularjs
requestSingleLogoutFilter是登出处理过滤器。主要是用来过滤客户端发起登出请求。XXUrlLogoutSuccessHandler 主要是用来处理登出后，再次登陆跳转地址问题。web

public class HisUrlLogoutSuccessHandler extends AbstractAuthenticationTargetUrlRequestHandler implements LogoutSuccessHandler {
@Value("${cas.portal.url}")
private String casPortalUrl;
private String casUrl;
public HisUrlLogoutSuccessHandler(String casUrl) {
this.casUrl = casUrl;
}
public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
String result = casUrl + URLEncoder.encode(casPortalUrl, "UTF-8");
if (StringUtils.hasText(result)) {
setDefaultTargetUrl(result);
}
super.handle(request, response, authentication);
}
}
XXSingleSignOutFilter主要用来处理单点登出。官方默认实现是 做废当前session。我集成了spring session。使用官方默认就能够。这里记录一下一种集群session删除思路。（redis）ajax
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import java.io.IOException;
import java.util.concurrent.atomic.AtomicBoolean;
/**

*/
public class XXSingleSignOutFilter extends AbstractConfigurationFilter {
private static final Log logger = LogFactory.getLog(HisSingleSignOutFilter.class);
@Autowired
private RedisOperationsSessionRepository repository;
@Value("${local.ip:000.000.000.000}")
private String localIp;
private static final SingleSignOutHandler handler = new SingleSignOutHandler();
private AtomicBoolean handlerInitialized = new AtomicBoolean(false);
public HisSingleSignOutFilter() {
}
public void init(FilterConfig filterConfig) throws ServletException {
if (!this.isIgnoreInitConfiguration()) {
handler.setArtifactParameterName(this.getPropertyFromInitParams(filterConfig, "artifactParameterName", "ticket"));
handler.setLogoutParameterName(this.getPropertyFromInitParams(filterConfig, "logoutParameterName", "logoutRequest"));
}
handler.init();
}
public void setArtifactParameterName(String name) {
handler.setArtifactParameterName(name);
}
public void setLogoutParameterName(String name) {
handler.setLogoutParameterName(name);
}
public void setSessionMappingStorage(SessionMappingStorage storage) {
handler.setSessionMappingStorage(storage);
}
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
if (handler.isTokenRequest(request)) {
handler.recordSession(request);
} else {
if (handler.isLogoutRequest(request)) {
handler.destroySession(request);
/**
* 配合session共享机制,经过cas server记录的sessionId删除session在redis中的缓存,这一步骤主要用于业务集群后,在反向代理状况下,单点登出时候cas server登出请求随机请求.
**/
String logoutMessage = CommonUtils.safeGetParameter(request, "logoutRequest");
String sessionId = XmlUtils.getTextForElement(logoutMessage, "SessionId");
System.out.println("单点删除-----------------------------------");
repository.delete(sessionId);
logger.info("logout session id is:" + sessionId +";local is is :" + this.localIp + ";cas server ip is:" + CommonHelper.analyzeClientIpAddress(request) + ";logout project is:" + ((HttpServletRequest) servletRequest).getContextPath());
return;
}
this.log.trace("Ignoring URI " + request.getRequestURI());
}
filterChain.doFilter(servletRequest, servletResponse);
}
public void destroy() {
}
protected static SingleSignOutHandler getSingleSignOutHandler() {
return handler;
}
}
cas配置基本如上。记录一下spring security 登陆部分。redis
import java.util.Collection;
import java.util.LinkedList;
import javax.annotation.Resource;
import org.springframework.beans.factory.config.ConfigurableBeanFactory;
import org.springframework.context.annotation.Scope;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service("casUserDetailsService")
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
@Transactional(readOnly = false)
public class CasUserDetailsServiceImpl implements UserDetailsService {
@Resource
private UserService userService;
@SuppressWarnings("finally")
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
UserDetailImpl userDetail = new UserDetailImpl();
try {
System.out.println("查询用户信息--------------------------");
User user = userService.queryUserByAccount(username);
// 复制查询到的用户信息到实现类
userDetail.setUserId(user.getUserId());
userDetail.setPassword(user.getPasswd());
userDetail.setUserName(username);
Collection<GrantedAuthority> authorities = new LinkedList<GrantedAuthority>();
/* List<GrantedAuthority> authorities = authorizationService.getAuthorities(token.getFunc());*/
authorities.add(new SimpleGrantedAuthority("ROLE_APP_USER"));
userDetail.setAuthorities(authorities);
/*Token token = authorizationService.getUserTokenByUserId(user);
Authentication auth = new PreAuthenticatedAuthenticationToken(token, token.getUser(), authorities);
auth.setAuthenticated(true);
SecurityContextHolder.getContext().setAuthentication(auth);*/
} catch (ServiceException e) {
e.printStackTrace();
} finally {
return userDetail;
}
}
}
根据cas返回的用户名查询 用户信息。 此处角色名称必须带上 ROLE_.spring
因为项目中获取用户信息时本身组装的 sessionDTO。并且是直接从httpsession中获取。故须要设置拦截器，注入用户信息。
servlet.xml中配置
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/dispatch/**" />
<bean class="com.xx.interceptor.UserSessionInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationToken;
import org.springframework.security.web.authentication.session.CompositeSessionAuthenticationStrategy;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
public class UserSessionInterceptor extends HandlerInterceptorAdapter {
@Resource
private AuthorizationService authorizationService;
@Resource(name = "")
private UserService userService;
@Autowired
private CompositeSessionAuthenticationStrategy sas;
static Logger log=LoggerFactory.getLogger(UserSessionInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
HttpSession session = request.getSession();
Object user = session.getAttribute("tUser");
if(user==null){
UserDetailImpl userDetail=(UserDetailImpl) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
User originalUser =new User();
originalUser.setUserCode(userDetail.getUsername());
originalUser.setPasswd(userDetail.getPassword());
try {
originalUser = userService.queryTUserbyUserCodeAndPwd(originalUser);
userService.queryAllDeptsAndAreas(originalUser);
//根据userId构造session用户。
Token token = authorizationService.getUserTokenByUserId(originalUser);
long loginTime = System.currentTimeMillis();
session.setAttribute("tUser", token.getUser());
session.setAttribute("loginUserCode", token.getUser().getUserCode());
session.setAttribute("token", token);
session.setAttribute("loginTime", loginTime);
Authentication auth = new PreAuthenticatedAuthenticationToken(token.getUser().getAccount(), token.getUser(),
null);
auth.setAuthenticated(true);
sas.onAuthentication(auth, request, response);
} catch (Exception e) {
log.error("session拦截器查询用户信息出错"+e);
}finally{
return true;
}
}
return true;
}
}
这样就能保证 cas回调回来访问 controller能跟普通登陆获取的session值同样。
重点来了！！前端如何处理
前面说了是返回json数据。那么前端必须拦截请求返回值，而且在返回以前 处理好cas单点登陆。
我前端使用的是angularjs。故设置一个http请求拦截器便可。angular也有对应的拦截器。
var MetronicApp = angular.module("MetronicApp", [ "ui.router", "ui.bootstrap",
"pascalprecht.translate",// 国际化
'mgcrea.ngStrap' // 弹框插件
]);
/*
*添加http拦截
*/
MetronicApp.config([ '$httpProvider', function($httpProvider) {
$httpProvider.interceptors.push('httpInterceptor');
$httpProvider.defaults.headers.post = {
'Content-Type' : 'application/x-www-form-urlencoded'
}
if (!$httpProvider.defaults.headers.get) {
$httpProvider.defaults.headers.get = {};
}
;
$httpProvider.defaults.headers.common["X-Requeste-with"] = "XMLHttpRequest";
$httpProvider.defaults.headers.get['Cache-Control'] = 'no-cache';
$httpProvider.defaults.headers.get['pragma'] = 'no-cache'
} ]);
MetronicApp.factory('httpInterceptor', [ '$q', '$injector', '$rootScope', '$window', '$timeout', function($q, $injector, $rootScope, $window, $timeout) {
var httpInterceptor = {
'responseError' : function(response) {
var sign = 1;
if (response.status == 404) {
var rootScope = $injector.get('$rootScope');
console.info(rootScope);
var state = $injector.get('$rootScope').$state.current.name;
console.info(state);
rootScope.stateBeforLogin = state;
rootScope.$state.go("home");
return $q.reject(response);
} else if (response.status == 417) {
return $q.reject(response);
} else if (response.status == 401) {
$window.location.href = "./#/403.html";
return $q.reject(response);
} else if (response.status == 500)
return $q.reject(response);
}
;
return $q.reject(response);
},
'response' : function(response) {
if(response.status==200 && response.data.casError=='4111'){ //前端先判断当前是否登陆，若是未登陆获取后端url进行cas跳转判断。 4111是后端定义的返回码
$.ajax({
//几个参数须要注意一下
type: "GET",//方法类型
dataType: "html",//预期服务器返回的数据类型
async: false, //同步是为了给当前业务请求返回数据。
url: response.data.redirect+"&method=POST" ,//url 加上method=POST 可让cas将ST以页面形式返回。 注意我这里将 cas服务端作了跨域处理。 必须设置授信证书。要不ajax有时候被浏览器拦截没法访问cas。
xhrFields: {
withCredentials: true // 这里设置了withCredentials 为了带上cookie
},
success: function (result) {
console.log(result);//打印服务端返回的数据(调试用)
if(result.indexOf("id=\"fm1\"")>0){ //判断是否cas登陆页。若是是登陆页则跳转登陆页。
alert("当前帐号未登陆，请先登陆");
window.location.href="./redirect.html";
}
//若是不是登陆页我这里直接正则匹配了返回的请求回调地址。
var reg=/action=\"(.*?)\"/g;
console.log(result.match(reg));
var url=result.match(reg)[0].replace(/action=\"/,"").replace(/\"/,"");
console.log(url);
var st_reg=/ST(.*?)\<\/textarea\>/g;
var st_val=result.match(st_reg)[0].replace(/\<\/textarea\>/,"");
console.log(st_val);
//拿到回调地址 拼接ticket 再次访问便可拿到 业务请求的返回值。
$.ajax({
//几个参数须要注意一下
type: "POST",//方法类型
dataType: "json",//预期服务器返回的数据类型
async: false,
url: url+"&ticket="+st_val ,//url
xhrFields: {
withCredentials: true // 这里设置了withCredentials
},
success: function (result) {
console.log(result);//打印服务端返回的数据(调试用)
response.data=result; //将业务请求返回值返回。 response是当前业务请求的响应。
},
error : function(error) {
alert("异常！");
}
});
},
error : function(error) {
alert("异常！");
}
});
}
return response;
},
'request' : function(config) {
//处理AJAX请求（不然后台IsAjaxRequest()始终false）
config.headers['X-Requested-With'] = 'XMLHttpRequest';
return config || $q.when(config);
},
'requestError' : function(config) {
return $q.reject(config);
}
}
return httpInterceptor;
} ]);
// 登陆
MetronicApp.controller('redirectCtrl',function($scope, $http, $window, $q, $interval, $rootScope,$timeout) {
var storage = window.sessionStorage;
var storageLocal = window.localStorage;
var loginParams = {};
var loginData = mergeReauestData('LoginController','getToken',loginParams);
var loginResult = sendPost($http,loginData, $q);
loginResult.then(function(success) {
var loginResult = JSON.parse(success);
// 登陆成功后，存储用户信息到storage的操做放到main.js中，页面初始化时
var token = loginResult.token;
var userinfo = loginResult.token.user;
storage.setItem('token',JSON.stringify(token));
storage.setItem('userinfo',JSON.stringify(userinfo));
storageLocal.setItem('loginTime',loginResult.loginTime);
// 登陆的时候存放下
setCookie("userId",userinfo.userId);
$window.location.href = "./#/home.html";
},function(error) {
windowAlert(JSON.parse(error).errMsg);
});
});
// # sourceURL=RedirectController.js
由于我是测试可行性故我在前端主页前加了一层。正常应该在主页中配置如上方法。由于个人redirect.html被拦截了 因此跳转会触发302重定向至cas。而后cas登陆后又会重定向至redirect.html 。最后页面ajax请求加载token，即实现了登陆。
若是是先后端分开部署应该在ajax请求中再加一层去设置登陆后的跳转主页。个人想法是：因为cas-client是将上一次访问页面都存储在了 session中 （SPRING_SECURITY_SAVED_REQUEST这么个key值中）。能够写一个接口让security不拦截 去设置主页 这样也能够实现。（DefaultSavedRequest没有set跳转路径的方法，不推荐重写）或者本身去重写AuthenticationSuccessHandler 实现本身的回调成功函数。默认是SavedRequestAwareAuthenticationSuccessHandler，拿到以前保存的路径重定向。
或者直接在后台定义一个重定一个重定向前端主页的接口。前端判断cas没有登陆后访问这个接口。让该接口被拦截。而后再point中特殊判断是该接口请求的话直接重定向至cas。这样cas跳转回来该接口又能重定向至前端。大功告成
为了解决跨域问题。我对cas服务端作了跨域处理
跳转页以下：

感谢https://gogo1217.iteye.com/blog/2425080提供的思路。虽然代码不全 可是提供了 method=POST的方法思路
总结： cas服务端是3.X。 method=POST、HEADER、GET 官网上说是5.x提供的方法。可是3.X也能经过ajax获取，故没有升级cas。3.x不支持HEADER
cas5.x 设置了POST 返回的是ST跳转页面。浏览器是看不出来的 建议本身用postman等调试。 设置HEADER时确实在头信息里返回了 ST信息等。可是我调试时疯狂重定向都懵逼了。 cas5.x官网说是在responseType中设置响应类型。能够在配置文件中指定类型。
下次介绍一下spring boot+spring security+cas的集成方式。
