Question

我已经使用CAS实现了Spring Security，并且正在尝试配置会话超时。我看到ticketExpirationPolicies.xml中的设置值会对此有所帮助。我尝试过配置值，但会话永远不会过期。我也试过在web.xml中设置会话到期时间。这是我的spring-application-context配置：

<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"

        </beans:property>
    </beans:bean>
    <beans:bean id="casEntryPoint"
        class="org.springframework.security.cas.web.CasAuthenticationEntryPoint">
        <beans:property name="loginUrl"
            value="https://myipaddress:8443/cas/login" />
        <beans:property name="serviceProperties" ref="serviceProperties" />
    </beans:bean>
    <beans:bean id="serviceProperties"
        class="org.springframework.security.cas.ServiceProperties">
        <beans:property name="service"

    <user-service id="userService">
        <user name="user1" password="user1" authorities="ROLE_ADMIN" />
    </user-service>

</beans:beans>

我在web.xml中有单点登录配置：

<listener>
    <listener-class>
        org.jasig.cas.client.session.SingleSignOutHttpSessionListener
    </listener-class>
  </listener>
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
    </filter-mapping>

我找到了解决方案。对于通过CAS进行身份验证的每个Web应用程序，需要在web.xml中设置自己的会话超时设置。一旦会话超时，它就会在CAS服务器上进行身份验证。如果票证有更长的使用寿命，您将被重定向到defaultTargetUrl（如果已指定）。如果故障单已过期，系统将再次提示您输入凭据。

我的配置方式是，将票证到期时保持与我的Web应用程序中的会话超时相同。一旦会话在我的Web应用程序中超时，它就会发现票证已经过期，因为有效期与Web应用程序的有效性相同，并提示再次登录。
