使用cas做单点登录，web.xml配置
1、 添加maven依赖
<dependency>
<groupId>org.jasig.cas.clientgroupId>
<artifactId>cas-client-coreartifactId>
<version>3.3.3version>
dependency>
2、 web.xml添加一下项，以tms为例

<filter-class>com.autostreets.web.cas.admin.shiro.filter.SSOFilterfilter-class>

com.autostreets.web.cas.admin.shiro.filter.SSOFilter 代码如下，供参考。
另外：tms集成的单点登录地址 http://passport.autostreets.com
Wms集成的单点登录地址 http://sso.autostreets.com
Wms的ssoFilter配置如下，和tms的文件稍微有点区别
<filter>
<filter-name>ssoFilterfilter-name>
