Spring整合Shiro做权限控制模块详细案例分析
1.引入Shiro的Maven依赖
<!-- Spring 整合Shiro需要的依赖 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.1</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.1</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-ehcache</artifactId> <version>1.2.1</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.1</version> </dependency> <!-- 除此之外还有一些东西也不可少spring, spring-mvc, ibatis等 spring.3.1.2 spring-mvc.3.1.2 ibatis.2.3.4 cglib.2.2 -->
2.web.xml中配置
<!-- 配置shiro的核心拦截器 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
3. 编写自己的UserRealm类继承自Realm，主要实现认证和授权的管理操作
package com.jay.demo.shiro; import java.util.HashSet; import java.util.Iterator; import java.util.Set; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authc.LockedAccountException; import org.apache.shiro.authc.SimpleAuthenticationInfo; import org.apache.shiro.authc.UnknownAccountException; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; import org.springframework.beans.factory.annotation.Autowired; import com.jay.demo.bean.Permission; import com.jay.demo.bean.Role; import com.jay.demo.bean.User; import com.jay.demo.service.UserService; public class UserRealm extends AuthorizingRealm{ @Autowired private UserService userService; /** * 授权操作 */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { // String username = (String) getAvailablePrincipal(principals); String username = (String) principals.getPrimaryPrincipal(); Set<Role> roleSet = userService.findUserByUsername(username).getRoleSet(); //角色名的集合 Set<String> roles = new HashSet<String>(); //权限名的集合 Set<String> permissions = new HashSet<String>(); Iterator<Role> it = roleSet.iterator(); while(it.hasNext()){ roles.add(it.next().getName()); for(Permission per:it.next().getPermissionSet()){ permissions.add(per.getName()); } } SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(); authorizationInfo.addRoles(roles); authorizationInfo.addStringPermissions(permissions); return authorizationInfo; } /** * 身份验证操作 */ @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { String username = (String) token.getPrincipal(); User user = userService.findUserByUsername(username); if(user==null){ //木有找到用户 throw new UnknownAccountException("没有找到该账号"); } /* if(Boolean.TRUE.equals(user.getLocked())) { throw new LockedAccountException(); //帐号锁定 } */ /** * 交给AuthenticatingRealm使用CredentialsMatcher进行密码匹配，如果觉得人家的不好可以在此判断或自定义实现 */ SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),getName()); return info; } @Override public String getName() { return getClass().getName(); } }
4.在Spring的applicationContext.xml中进行Shiro的相关配置
1、添加shiroFilter定义
<!-- Shiro Filter --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager" /> <property name="loginUrl" value="/login" /> <property name="successUrl" value="/user/list" /> <property name="unauthorizedUrl" value="/login" /> <property name="filterChainDefinitions"> <value> /login = anon /user/** = authc /role/edit/* = perms[role:edit] /role/save = perms[role:edit] /role/list = perms[role:view] /** = authc </value> </property> </bean>
2、添加securityManager定义
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="myRealm" /> </bean>
3、添加realm定义
<bean id=" myRealm" class="com.jay.demo.shiro.UserRealm/>
4、配置EhCache
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager" />
5、保证实现了Shiro内部lifecycle函数的bean执行
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
特别注意：
如果使用Shiro相关的注解，需要在springmvc-servlet.xml中配置一下信息
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean>
备注：Shiro权限管理的过滤器解释：
默认过滤器(10个)
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
anon：例子/admins/**=anon 没有参数，表示可以匿名使用。
authc：例如/admins/user/**=authc表示需要认证(登录)才能使用，没有参数
roles：例子/admins/user/**=roles[admin],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，当有多个参数时，例如admins/user/**=roles["admin,guest"],每个参数通过才算通过，相当于hasAllRoles()方法。
perms：例子/admins/user/**=perms[user:add:*],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，例如/admins/user/**=perms["user:add:*,user:modify:*"]，当有多个参数时必须每个参数都通过才通过，想当于isPermitedAll()方法。
rest：例子/admins/user/**=rest[user],根据请求的方法，相当于/admins/user/**=perms[user:method] ,其中method为post，get，delete等。
port：例子/admins/user/**=port[8081],当请求的url的端口不是8081是跳转到schemal://serverName:8081?queryString,其中schmal是协议http或https等，serverName是你访问的host,8081是url配置里port的端口，queryString是你访问的url里的？后面的参数。
authcBasic：例如/admins/user/**=authcBasic没有参数表示httpBasic认证
ssl：例子/admins/user/**=ssl没有参数，表示安全的url请求，协议为https
user：例如/admins/user/**=user没有参数表示必须存在用户，当登入操作时不做检查
关于Shiro的标签应用：
<shiro:authenticated> 登录之后 <shiro:notAuthenticated> 不在登录状态时 <shiro:guest> 用户在没有RememberMe时 <shiro:user> 用户在RememberMe时 <shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色时 <shiro:hasRole name="abc"> 拥有角色abc <shiro:lacksRole name="abc"> 没有角色abc <shiro:hasPermission name="abc"> 拥有权限abc <shiro:lacksPermission name="abc"> 没有权限abc <shiro:principal> 显示用户登录名
以上是Shiro的相关配置，出于安全的考虑，一般都会使用ACL(基于角色的用户权限管理去控制用户登录后的权限)
