cas 认证流程

一 配置实例

应用场景： cas 服务部署在192.168.7.115 ，是一个web 应用，访问地址为：https://cas.mycompany.com:8443/cas/ 。web1 应用位于192.168.7.90 ，访问地址为：http://192.168.7.90:8081/web1 ,web2 应用位于192.168.7.90 ，访问地址为：http://192.168.7.90:8082/web2 。web1 和web2 通过cas 服务实现SSO 功能。浏览器位于本地localhost 。

 

cas 服务器： 172.16.52.35 启动8443 端口，需配置证书

 

web1 : 172.16.52.35

   hosts 配置： 172.16.52.35  cas.mycompany.com

    web.xml 里的配置：

    <context-param>

        <param-name>casServerUrlPrefix</param-name>

        <param-value>https://cas.mycompany.com:8443/cas/</param-value>

    </context-param>

    <context-param>

        <param-name>serverName</param-name>

        <param-value>172.16.52.35:8081</param-value>

    </context-param>

    <filter>

        <filter-name>CAS Authentication Filter</filter-name>

<filter-class>

org.jasig.cas.client.authentication.AuthenticationFilter

</filter-class>

        <init-param>

           <param-name>casServerLoginUrl</param-name>

           <param-value>https://cas.mycompany.com:8443/cas/login</param-value>

        </init-param>

    </filter>

    <filter>

        <filter-name>CAS Validation Filter</filter-name>

        <filter-class>

org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter

</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>CAS Authentication Filter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <filter-mapping>

        <filter-name>CAS Validation Filter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

 

    JDK 启动参数需加上( 验证CAS 服务器证书的需要) ：
