本文环境：

1、apache-tomcat-7.0.50-windows-x86

2、cas-server-3.4.11

3、cas-client-3.2.1

将cas-server-webapp-3.4.11.war放入tomcat的webapps下，改名ROOT.war，启动tomcat，待自动解压后，进行如下修改：

1、修改WEB-INF\deployerConfigContext.xml，加入

[html] view plain copy

p:requireSecure="false"

[html] view plain copy

<property name="authenticationHandlers">
<list>
<!--
| This is the authentication handler that authenticates services by means of callback via SSL, thereby validating
| a server side SSL certificate.
+-->
<bean class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
p:httpClient-ref="httpClient" p:requireSecure="false"/>
<!--
| This is the authentication handler declaration that every CAS deployer will need to change before deploying CAS
| into production. The default SimpleTestUsernamePasswordAuthenticationHandler authenticates UsernamePasswordCredentials
| where the username equals the password. You will need to replace this with an AuthenticationHandler that implements your
| local authentication strategy. You might accomplish this by coding a new such handler and declaring
| edu.someschool.its.cas.MySpecialHandler here, or you might use one of the handlers provided in the adaptors modules.
+-->
<bean
class="org.jasig.cas.authentication.handler.support.SimpleTestUsernamePasswordAuthenticationHandler" />
</list>
</property>

2、修改WEB-INF\spring-configuration\ticketGrantingTicketCookieGenerator.xml，修改p:cookieSecure="false"

[html] view plain copy

<bean id="ticketGrantingTicketCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
p:cookieSecure="false"
p:cookieMaxAge="-1"
p:cookieName="CASTGC"
p:cookiePath="/cas" />

3、修改修改WEB-INF\spring-configuration\warnCookieGenerator.xml，修改p:cookieSecure="false"

[html] view plain copy

<bean id="warnCookieGenerator" class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
p:cookieSecure="false"
p:cookieMaxAge="-1"
p:cookieName="CASPRIVACY"
p:cookiePath="/cas" />

经过以上三步，cas server端修改完毕

客户端操作我习惯进行一下域名/IP映射，修改：C:\Windows\System32\drivers\etc\hosts 添加如下映射

[java] view plain copy

127.0.0.1 cas.jkkl1314.com
127.0.0.1 c1.jkkl1314.com
127.0.0.1 c2.jkkl1314.com

在客户端项目中加入cas-client-core-3.2.1.jar、commons-logging.jar，并在web.xml中加入：

[html] view plain copy

<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>
</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>http://cas.jkkl1314.com:10000</param-value>
</init-param>
<init-param>
<param-name>serverName</param-name>
<param-value>http://c1.jkkl1314.com:8080</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CAS Filter</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://cas.jkkl1314.com:10000</param-value>
</init-param>
<init-param>
<param-name>serverName</param-name>
<param-value>http://c1.jkkl1314.com: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>

第二个客户端项目只是修改了一下域名，在web.xml中加入的配置是一样的！运行后即可实现单点登录！
