抛弃Https让Cas以Http协议提供单点登录服务

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

 p:requireSecure="false"

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

<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"

<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

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：

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

<!-- 用于单点退出，该过滤器用于实现单点登出功能，可选配置-->

<listener>

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

</listener>


<!-- 该过滤器用于实现单点登出功能，可选配置。 -->

<!--

该过滤器负责实现HttpServletRequest请求的包裹，

<!--

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>


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

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！

以下两边文章对我帮助很大，特此感谢：
