前面的文章讲了SpringBoot集成CAS单点登录，我们可以看出，使用了很多的过滤器，那么在这个地方SpringMVC集成CAS我们应该怎样做呢？同样应该使用过滤器，将相应的过滤器添加到web.xml文件中。具体代码如下：

	<!--
	****
	  支持单点登录
	****
	-->
	<!-- 单点退出 -->
	<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>
		<init-param>
			<param-name>casServerLogoutUrl</param-name>
			<param-value>http://localhost:9999/logout</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CAS Single Sign Out Filter</filter-name>
		<url-pattern>/loginController.do?logout</url-pattern>
	</filter-mapping>

	<!-- 该filter负责对请求进行登录验证拦截 -->
	<filter>
		<filter-name>CAS Authentication Filter</filter-name>
		<filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>
		<init-param>
			<param-name>casServerLoginUrl</param-name>
			<param-value>http://localhost:9999/login</param-value>
		</init-param>
		<init-param>
			<param-name>serverName</param-name>
			<param-value>http://localhost:8888/loginController.do?login</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CAS Authentication Filter</filter-name>
		<url-pattern>/login</url-pattern>
	</filter-mapping>

	<!-- 该filter负责对请求参数ticket进行验证 -->
	<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>http://localhost:9999/</param-value>
		</init-param>
		<init-param>
			<param-name>serverName</param-name>
			<param-value>http://localhost:8888/</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CAS Validation Filter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- HttpServletRequest包裹类，支持getUserPrincipal，getRemoteUser方法取得用户信息 -->
	<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>

	<!-- 把Assertion信息放在ThreadLocal变量中，不在web层也能获取当前登录信息 -->
	<!--<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>/loginController.do?login</url-pattern>-->
	<!--</filter-mapping>-->
