Cas单点登录(6)Cas Client配置

1、新建项目

新建javaEE项目CasClient，添加jar包cas-client-core-3.2.1.jar

2、修改web.xml

向javaEE项目的WEB-INF/web.xml添加以下代码

<!-- ======================== 单点登录开始 ======================== -->
<!-- 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>

    <!-- 该过滤器负责用户的认证工作，必须启用它 -->
<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>http://Cas Server的ip:端口号/cas/login</param-value>
        </init-param>
        <init-param>
            <param-name>serverName</param-name>
            <param-value>http://client服务器ip:端口号</param-value>
        </init-param>
</filter>

    <!-- 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.Cas10TicketValidationFilter</filter-class>
        <init-param>
            <param-name>casServerUrlPrefix</param-name>
            <param-value>http://Cas Server的ip:端口号/cas</param-value>
        </init-param>
        <init-param>
            <param-name>serverName</param-name>
            <param-value>http://client服务器ip:端口号</param-value>
        </init-param>
        <init-param>
            <param-name>redirectAfterValidation</param-name>
            <param-value>true</param-value>
        </init-param>
</filter>

<!-- 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>

<!-- 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 Single Sign Out Filter</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>
<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>
<filter-mapping>
        <filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
        <filter-name>CAS Assertion Thread Local Filter</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>

<!-- ======================== 单点登录结束 ======================== -->

<!-- 所有 filter 结束后添加 logout 的 listener -->
<!-- 用于单点退出 -->
<listener>
        <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>
</listener>

3、测试

1. 启动Cas Server所在Tomcat；
2. 将项目CasClient放入各自对应的Client服务器中后，启动三个Client服务器所在Tomcat；
3. 输入任意Client对应的网址：http://client服务器ip:端口号/CasClient，若自动跳转至Cas Server登录页面，账号密码输入成功后跳转回Client页面。再输入其他任意Client对应网址后，免登陆直接显示Client页面，则说明配置成功。
