1. 导出证书
以上操作会在当前目录产生文件:ssodemo.crt(需要用到的文件请看CAS服务端配置那篇文章)
2. 客户端导入证书
以上操作会在jdk安装目录jrelibsecurity下产生文件:cacerts
注意:多台电脑要重复以上操作,每个jdk都要导入这个文件
另一种导入证书的方法详见:http://www.cnblogs.com/cxyj/p/3884507.html
3. 添加cas客户端jar包到自己需要单点登录的web应用web-inf/lib目录下
下载地址:http://downloads.jasig.org/cas-clients/
或者maven配置:
<dependency> <groupId>org.jasig.cas.client</groupId> <artifactId>cas-client-core</artifactId> <version>3.2.1</version> </dependency>
4. 配置web.xml 文件
<!-- ======================== 单点登录开始 ======================== --> <!-- 用于单点退出,该过滤器用于实现单点登出功能,可选配置--> <listener> <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class> </listener> <!-- 该过滤器用于实现单点登出功能,可选配置。 --> <filter> <filter-name>CAS Single Sign Out Filter</filter-name> <filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class> </filter> <filter-mapping> <filter-name>CAS Single Sign Out Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter> <filter-name>CAS Filter</filter-name> <filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class> <init-param> <param-name>casServerLoginUrl</param-name> <param-value>https://localhost:8443/cas/login</param-value> </init-param> <init-param> <param-name>serverName</param-name> <param-value>http://localhost:8080</param-value> </init-param> </filter> <filter-mapping> <filter-name>CAS Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 该过滤器负责对Ticket的校验工作,必须启用它 --> <filter> <filter-name>CAS Validation Filter</filter-name> <filter-class> org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter</filter-class> <init-param> <param-name>casServerUrlPrefix</param-name> <param-value>https://localhost:8443/cas</param-value> </init-param> <init-param> <param-name>serverName</param-name> <param-value>http://localhost:8080</param-value> </init-param> </filter> <filter-mapping> <filter-name>CAS Validation Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 该过滤器负责实现HttpServletRequest请求的包裹, 比如允许开发者通过HttpServletRequest的getRemoteUser()方法获得SSO登录用户的登录名,可选配置。 --> <filter> <filter-name>CAS HttpServletRequest Wrapper Filter</filter-name> <filter-class> org.jasig.cas.client.util.HttpServletRequestWrapperFilter</filter-class> </filter> <filter-mapping> <filter-name>CAS HttpServletRequest Wrapper Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 该过滤器使得开发者可以通过org.jasig.cas.client.util.AssertionHolder来获取用户的登录名。 比如AssertionHolder.getAssertion().getPrincipal().getName()。 --> <filter> <filter-name>CAS Assertion Thread Local Filter</filter-name> <filter-class>org.jasig.cas.client.util.AssertionThreadLocalFilter</filter-class> </filter> <filter-mapping> <filter-name>CAS Assertion Thread Local Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- ======================== 单点登录结束 ======================== -->
以上配置中https://localhost:8443/cas 为cas服务端路径 http://localhost:8080为当前web项目的路径
