Cas单点登录(7)Cas登录过期时间

1、修改Cas Server的CASTGC过期时间

修改Cas Server下cas/WEB-INF/spring-configuration/ticketExpirationPolicies.xml（CASTGC的过期时间，单位为秒）

<bean id="grantingTicketExpirationPolicy" class="org.jasig.cas.ticket.support.TicketGrantingTicketExpirationPolicy"     p:maxTimeToLiveInSeconds="28800"     p:timeToKillInSeconds="1800"/>

2、修改Cas Client的Session过期时间

向Cas Client下WEB-INF/web.xml添加以下代码（Session过期时间，单位为分钟）：

  <!-- ==================== Default Session Configuration ================= -->  <!-- You can set the default session timeout (in minutes) for all newly   -->  <!-- created sessions by modifying the value below.                       -->    <session-config>        <session-timeout>30</session-timeout>    </session-config>
