这样如果访问www.example.com/admin/index.html时，如果没登录就会跳到cas去登录，登录成功后跳转回当前页面。

如果想获得cas返回的更多用户的信息，比如：用户名，用户id，用户邮箱等，可以添加一个过滤器，这个过滤器必须在shiro的过滤器后面，否则获取不到相关的信息。过滤器代码如下：

[main]casFilter = org.apache.shiro.cas.CasFilter#配置验证错误时的失败页面casFilter.failureUrl = /error.jsp#配置casRealmcasRealm = org.apache.shiro.cas.CasRealmcasRealm.defaultRoles = ROLE_USERcasRealm.casServerUrlPrefix = https://www.cas.com#客户端的回调地址设置，必须和下面的shiro-cas过滤器拦截的地址一致casRealm.casService = http://www.example.com/shiro-cas#如果要实现cas的remember me的功能，需要引入下面两个配置casSubjectFactory = org.apache.shiro.cas.CasSubjectFactorysecurityManager.subjectFactory = $casSubjectFactory#设定角色的登录链接，这里为cas登录页面的链接可配置回调地址roles.loginUrl = https://www.<span style="color:#000000;">cas</span>.com/login?service=http://shop.youboy.com:8080/cshop/shiro-cas[urls]#设定shiro-cas过滤器拦截的地址/shiro-cas = casFilter/admin/** = roles[ROLE_USER]/** = anon

最近，由于工作的需要自己封装了一个对对文件夹的操作的类（CDirectory）。
有了这个类之后我们对文件操作就显得十分的简单，在这里就不废话了。首先来看一下怎么使用这个CDirectory。
CDirectory类实现了对奇迹私服的创建、删除、拷贝、取得文件夹的大小、检查奇迹私服的存在与否和从指定的文件夹中查找指定的后缀名。

shiro.ini配置

我是用maven管理项目的，先引入shiro的jar包

获取到信息就可以把它设置到session或怎样由你定。

<filter><filter-name>shiroFilter</filter-name><filter-class>org.apache.shiro.web.servlet.IniShiroFilter</filter-class><init-param><param-name>configPath</param-name><param-value>classpath:META-INF/shiro/shiro.ini</param-value></init-param></filter><filter-mapping><filter-name>shiroFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

public void doFilter(ServletRequest request, ServletResponse response,      FilterChain chain) throws IOException, ServletException {        PrincipalCollection principalCollection = SecurityUtils.getSubject()        .getPrincipals();        if (principalCollection != null) {            List principals = principalCollection.asList();      // 这里获取到的list有两个元素，      //一个是cas返回来的用户名，举例是aaa，      //一个是cas返回的更多属性的map对象，举例是{uid:aaa,username:aaa,email:aaa}      //通过principals.get(1)来获得属性集合的map对象      Map<String,String> attributes = (Map<String,String>) principals.get(1);      if (principals != null) {        String email = attributes.get("email");        String username = attributes.get("username");        String uid = attributes.get("uid");        //对获取到的信息进行再处理      }    }        chain.doFilter(request, response);  }

配置web.xml，添加shiro过滤器

这里需要注意的是casRealm.casService设置的回调地址必须和下面casFilter的地址保持一致，否则无法验证成功。更多有关shiro的配置可以参考

其中shiro.ini为shiro配置文件，可以根据具体情况指定其路径。

由于项目需要做权限管理的功能，最先想到的是spring security，它是个功能强大的安全管理框架，不过它的复杂性和学习曲线之曲折让人生畏，转而寻求其它解决方案，知道另外一个项目组的人使用shiro做权限管理后就了解了下这个框架，发现比spring security简洁多了，于是就打算使用这个框架，首先嘛，当然是要和现在的系统进行集成，现在系统采用cas来做登录验证，所以先把cas和shiro进行集成。查看shiro官网，发现有个cas模块，下载试用，下面是集成方法，假设你已经搭建好cas服务器（具体搭建细节自己google破天一剑私服下）
