Apache Shrio安全框架
一、Shiro整体概述
1.简介
Apache Shiro是Java的一个安全框架,功能强大,使用简单,Shiro为开发人员提供了一个直观而全面的认证(登录),授权(判断是否含有权限),加密(密码加密)及会话管理(Shiro内置Session)的解决方案.
2.Shiro组件
3.Shiro架构
3.1 外部架构(以应用程序角度)
3.2 内部架构
4. Shiro的过滤器
过滤器简称 | 对应的java类 |
anon | org.apache.shiro.web.filter.authc.AnonymousFilter |
authc | org.apache.shiro.web.filter.authc.FormAuthenticationFilter |
authcBasic | org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter |
perms | org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter |
port | org.apache.shiro.web.filter.authz.PortFilter |
rest | org.apache.shiro.web.filter.authz.HttpMethodPermissionFilter |
roles | org.apache.shiro.web.filter.authz.RolesAuthorizationFilter |
ssl | org.apache.shiro.web.filter.authz.SslFilter |
user | org.apache.shiro.web.filter.authc.UserFilter |
logout | org.apache.shiro.web.filter.authc.LogoutFilter |
挑几个重要的说明一下:
anon:匿名过滤器,不登录也可以访问的资源使用,比如首页,一些静态资源等
authc:认证过滤器,登录成功后才能访问的资源使用
perms:授权过滤器,必须具备某种权限才能访问
roles:角色过滤器,必须具备某种角色才能访问
注意:这么多过滤器,使用起来肯定不方便,Shiro框架也考虑到了这一点,所以有一个过滤器,一个顶十个,即DelegatingFilterProxy.
5. Shiro与Spring整合
5.1 pom.xml
<!--shiro和spring整合--> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.3.2</version> </dependency>
5.2 web.xml
<filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
