CAS 4.0 配置开发手册

1    下载

地址http://downloads.jasig.org/

cas-server-4.0.0-release.tar.gz

cas-client-3.3.3-release.tar.gz

2    配置

解压cas-server-4.0.0，将其中module/cas-server-webapp-4.0.0.war复制到Tomcat的webapps目录下，重命名为cas.war，启动Tomcat解开压缩。

2.1 CAS的HTTP模式与HTTPS设置


1）cas\WEB-INF\deployerConfigContext.xml，新增p:requireSecure="false"

<bean id="proxyAuthenticationHandler"          class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"

p:httpClient-ref="httpClient" p:requireSecure="false"/>

2）cas\WEB-INF\spring-configuration

ticketGrantingTicketCookieGenerator.xml设置p:cookieSecure="false"

warnCookieGenerator.xml设置p:cookieSecure="false"

http://localhost:8080/cas，进入登录页面。

默认用户为casuser/Mellon，登录成功即配置完成。

2.2 设置利用数据库来验证用户

需依赖：c3p0-0.9.1.2.jar，mysql-connector-java-5.1.21.jar，cas-server-support-jdbc-4.0.0.jar


cas\WEB-INF\deployerConfigContext.xml

1）更换验证方式

<!--

<bean id="primaryAuthenticationHandler"

class="org.jasig.cas.authentication.AcceptUsersAuthenticationHandler">

<property name="users">

<map>

<entry key="casuser" value="Mellon"/>

</map>

</property>

</bean>

-->

<!-- Define the DB Connection -->

<bean id="dataSource"

class="com.mchange.v2.c3p0.ComboPooledDataSource"

p:driverClass="com.mysql.jdbc.Driver"

p:jdbcUrl="jdbc:mysql://127.0.0.1:3306/hztraffic?useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull"

p:user="root"

p:password="root" />

<!-- Define the encode method-->

<!--<bean id="passwordEncoder"

class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder" autowire="byName">

<constructor-arg value="MD5"/>

</bean> -->

<bean id="passwordEncoder"

class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder"

c:encodingAlgorithm="MD5"

p:characterEncoding="UTF-8" />

<bean id="dbAuthHandler"

class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler"

p:dataSource-ref="dataSource"

p:sql="select password from hztraffic.user_data where name=? and used=1"

p:passwordEncoder-ref="passwordEncoder"/>

<!-- p:passwordEncoder-ref="passwordEncoder" -->

2）更换验证Handle

<bean id="authenticationManager" class="org.jasig.cas.authentication.PolicyBasedAuthenticationManager">

<constructor-arg>

<map>

<!--

| IMPORTANT

| Every handler requires a unique name.

| If more than one instance of the same handler class is configured, you must explicitly

| set its name to something other than its default name (typically the simple class name).

-->

<entry key-ref="proxyAuthenticationHandler" value-ref="proxyPrincipalResolver" />

<entry key-ref="dbAuthHandler" value-ref="primaryPrincipalResolver" />

<!-- <entry key-ref="primaryAuthenticationHandler" value-ref="primaryPrincipalResolver" /> -->

</map>

</constructor-arg>

http://localhost:8080/cas，进入登录页面。

默认用户为casuser/Mellon，登录成功即配置完成。

3    编译

3.1 Eclipse导入工程

3.2 License文件设置

Failed goal com.mycila.maven-license-plugin

注意src目录与cas-server-webapp平级，此外，任何关于Sever文件的修改，文件头的License声明需要添加。JSP/JS/CSS，否则编译检测通过不了。

4    定制

4.1 登录/登出页面

4.2 允许退出后重定向

5    接入

5.1 WEB接入

5.1.1 非Spring模式

在Client工程WEB-INF/lib下添加cas-client-core-3.2.1.jar包。

修改web.xml如下：


<!-- ======================== 单点登录/登出 ======================== -->

<!-- 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>

</init-param>

<init-param>

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

<param-value>http://localhost:8080</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>https://localhost:8443/cas</param-value>

</init-param>

<init-param>

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

<param-value>http://localhost:8080</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>

<listener>

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

</listener>

<!-- ======================== 单点登录/登出结束 ======================== -->

现在运行Client工程，首次访问任一页面就会跳转到https://localhost:8443/cas/login进行认证。同时，把你的退出链接设置为：https://sso.wsria.com/cas/logout 即可实现单点推出。

5.1.2 Spring方式

引用cas-client-core.jar

Web.xml，注意casSingleSignOutFilter必须位于最前面


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

</listener>

<!-- ======================== 单点登录/登出 ======================== -->
