由于多个项目需要帐号的互通,所以一开始就是用cas去做的,不得不说cas要配置的东西挺多的,但是项目安全性不需要太高,所以没有做https的请求,也就是没有弄证书,这虽然省了很多时间和精力,但是项目之间的安全性降低了不少。
- <bean id="ticketGrantingTicketCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
- p:cookieSecure="false"
- p:cookieMaxAge="-1"
- p:cookieName="CASTGC"
- p:cookiePath="/cas" />
3.配置登录的验证逻辑, 修改配置文件cas\WEB-INF\deployerConfigContext.xml。在authenticationHandlers中配置验证方式,我这里配置数据库查询语句来实现用户名和密码的验证。
- <property name="authenticationHandlers">
- <list>
- <!--
- | This is the authentication handler that authenticates services by means of callback via SSL, thereby validating
- | a server side SSL certificate.
- +-->
- <bean class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
- p:httpClient-ref="httpClient" />
- <!--
- | This is the authentication handler declaration that every CAS deployer will need to change before deploying CAS
- | into production. The default SimpleTestUsernamePasswordAuthenticationHandler authenticates UsernamePasswordCredentials
- | where the username equals the password. You will need to replace this with an AuthenticationHandler that implements your
- | local authentication strategy. You might accomplish this by coding a new such handler and declaring
- | edu.someschool.its.cas.MySpecialHandler here, or you might use one of the handlers provided in the adaptors modules.
- +-->
- <!-- <bean
- class="org.jasig.cas.authentication.handler.support.SimpleTestUsernamePasswordAuthenticationHandler" /> -->
- <bean class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler">
- <property name="sql" value="select password from userTable where userName=?" />
- <property name="passwordEncoder" ref="passwordEncoder"/>
- <property name="dataSource" ref="dataSource" />
- </bean>
- </list>
- </property>
密码加密方法我这里使用MD5, 配置passwordEncoder的bean
- <bean id="passwordEncoder" class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder" autowire="byName">
- <constructor-arg value="MD5"/>
- </bean>
在配置一个名称为dataSource的数据源
- <bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource">
- <property name="driver" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"></property>
- <property name="driverUrl" value="jdbc:sqlserver://localhost:1433;databaseName=testDB;"></property>
- <property name="user" value="sa"></property>
- <property name="password" value="123456"></property>
- <property name="maximumConnectionCount" value="100"></property>
- <property name="minimumConnectionCount" value="1"></property>
- </bean>
数据源的配置根据自己的实际情况来配置, 需要的jar如果lib下面没有,自己复制进去, 不然数据源连不上报错。
然后就是java客户端的配置

- <!-- CAS 单点登录(SSO) 过滤器配置 (end) -->
4. 注意上步配置文件中,过滤器CasForInvokeContextFilter的实现是需要在具体的应用中实现的,他的目的是, CAS服务端登录验证成功后,会将登录用户的用户名携带回来, 这时客户端web应用程序需要根据用户名从数据库用户表中查询到用户的Id等信息, 并填充到Session中, 这样,客户端应用程序原来的验证逻辑就不会出问题了, 因为我们一般都是通过验证session中是否含有当前登录的用户的ID来进行登录验证的。
- /**
- * 该过滤器用户从CAS认证服务器中获取登录用户用户名,并填充必要的Session.
- * @author jiarong_cheng
- * @created 2012-7-12
- */
- public class CasForInvokeContextFilter implements Filter {
- @Override
- public void destroy() {
- }
- @Override
- public void doFilter(ServletRequest request, ServletResponse response,
- FilterChain chain) throws IOException, ServletException {
- HttpSession session = ((HttpServletRequest) request).getSession();
- //如果session中没有用户信息,则填充用户信息
- if (session.getAttribute("j_userId") == null) {
- //从Cas服务器获取登录账户的用户名
- Assertion assertion = AssertionHolder.getAssertion();
- String userName = assertion.getPrincipal().getName();
- try {
- //根据单点登录的账户的用户名,从数据库用户表查找用户信息, 填充到session中
- User user = UserDao.getUserByName(userName);
- session.setAttribute("username", userName);
- session.setAttribute("userId", user.getId());
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- chain.doFilter(request, response);
- }
- @Override
- public void init(FilterConfig config) throws ServletException {
- }
- }
到此,就完成了, 当你访问具体应用的网址, 如http://具体应用IP: 8080/ ,就会跳转到CAS服务器的登陆页面: http://CAS服务器IP: 8080/ 进行登录验证, 验证通过后, 又会跳转回应用的网址。
新建php工程:Phpcasclient1,将CAS文件夹和CAS.php复制到工程中,修改CAS/client.php,将其中的https改为http,将docs/examples/example_simple.php
复制到工程中,修改如下:
- <?php
- //
- // phpCAS simple client
- //
- // import phpCAS lib
- include_once('CAS.php');
- phpCAS::setDebug();
- // initialize phpCAS
- phpCAS::client(CAS_VERSION_2_0,'192.168.18.8',8080,'cas');
- // no SSL validation for the CAS server
- phpCAS::setNoCasServerValidation();
- // force CAS authentication
- phpCAS::forceAuthentication();
- // at this step, the user has been authenticated by the CAS server
- // and the user's login name can be read with phpCAS::getUser().
- // logout if desired
- if (isset($_REQUEST['logout'])) {
- $param=array("service"=>"http://localhost/Phpcasclient1/example_simple.php");//退出登录后返回
- phpCAS::logout($param);
- }
- // for this test, simply print that the authentication was successfull
- ?>
- <html>
- <head>
- <title>phpCAS simple client</title>
- </head>
- <body>
- <h1>Successfull Authentication!这是客户端1</h1>
- <p>the user's login is <b><?php echo phpCAS::getUser(); ?></b>.</p>
- <p>phpCAS version is <b><?php echo phpCAS::getVersion(); ?></b>.</p>
- <p><a href="http://192.168.18.8:8989/Casclient1/index.jsp">去java客户端1</a></p>
- <p><a href="?logout=">退出</a></p>
- </body>
- </html>
php配置需要开启php_curl,可以复制Phpcasclient1为Phpcasclient2
访问:http://localhost/Phpcasclient1/example_simple.php,跳转到登录页面,登录成功后访问Phpcasclient2,不需要登录,
php单点登录成功,这时再访问java客户端发现也不需要登录,php和java应用之间单点登录成功。
注:php的phpCAS::client(CAS_VERSION_2_0,'192.168.18.8',8080,'cas');地址需要和java的web.xml中的cas服务器地址一致,我开始一个写的ip:192.168.18.8,一个写的localhost,
php和java总是不能同步登录,郁闷了好久
----------------到这里java和php的客户端已经配置完成,现在你会发现php和java之间不能单点登出,php端退出java客户端也退出,反之java退出但是php却没有同步退出
这里需要做一个配置,在
phpCAS::setNoCasServerValidation();
// force CAS authentication
phpCAS::forceAuthentication();
这里加上
phpCAS::setNoCasServerValidation();
// force CAS authentication
phpCAS::handleLogoutRequests(); 这里会检测服务器端java退出的通知,就能实现php和java间同步登出了。
phpCAS::forceAuthentication();
