cas忽略地址配置

 项目中需要忽略部分地址不需要cas验证，网上资料不多，结合cas源码，找到了配置方法：
web.xml中增加ignorePattern配置。实际上是通过正则表达式来匹配。

• <filter>
• <filter-name>CAS Authentication Filter</filter-name>
• <filter-class>com.hyjx.framework.sso.HyjxAuthenticationFilter</filter-class>
• <init-param>
• <param-name>casServerLoginUrl</param-name>
• <param-value>http://172.22.0.46:9090/login</param-value>
• </init-param>
• <init-param>
• <param-name>serverName</param-name>
• <param-value>http://172.22.27.251:8080</param-value>
• </init-param>
• <init-param>
• <param-name>ignorePattern</param-name>
• <param-value>
• /index/|/userManager/|/login/ <!-- url中包含index、userManager、login会被忽略 -->
• </param-value>
• </init-param>
• </filter>
