单点登录Java客户端集成

发布时注意修改 web.xml 中的cas server 和当前中转站点的地址，同时还需要在 index.jsp 中修改综合平台的授权处理地址。

一 maven依赖：

<dependency>
    <groupId>org.jasig.cas.client</groupId>
    <artifactId>cas-client-core</artifactId>
    <version>3.4.1</version>
</dependency>
<dependency>
    <groupId>org.jasig.cas.client</groupId>
    <artifactId>cas-client-integration-tomcat-v7</artifactId>
    <version>3.4.1</version>
</dependency>

• 要求jdk7+，tomcat7+

二 web.xml中资源拦截：

<listener>
    <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>
</listener>

<filter>
    <filter-name>CAS Single Sign Out Filter</filter-name>
    <filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class>
    <init-param>
        <param-name>casServerUrlPrefix</param-name>
        <param-value>http://42.96.165.198:8591/cas</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>CAS Single Sign Out Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<filter>
    <filter-name>CASFilter</filter-name>
    <filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>
    <init-param>
        <param-name>casServerLoginUrl</param-name>
        <param-value>http://42.96.165.198:8591/cas/login</param-value>
    </init-param>
    <init-param>
        <param-name>serverName</param-name>
        <param-value>http://localhost:8180/cas-client</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>CASFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<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>http://42.96.165.198:8591/cas</param-value>
    </init-param>
    <init-param>
        <param-name>serverName</param-name>
        <param-value>http://localhost:8180/cas-client</param-value>
    </init-param>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>CAS Validation Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<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>

<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>

• http://localhost:8180/cas-client需要改成客户端自己的访问路径
• 以上配置<url-pattern>/*</url-pattern>拦截了客户端所有访问请求，需根据自身要求修改

三 用户信息获取：

AttributePrincipal principal = (AttributePrincipal) request.getUserPrincipal();
String userId = principal.getName();
Map attributes = principal.getAttributes();
String userName = (String) attributes.get("userName");
String userCode = (String) attributes.get("userCode");
String sex = (String) attributes.get("sex");
String mobile = (String) attributes.get("mobile");

• 用户登录成功之后会自动调转到当前被拦截的页面，可以在当前页面获取用户信息
