shiro权限项目中的简单应用
SpringMVC+maven
项目需要使用shiro，所以自学了几天，仅提供给新手，请根据文档查看…该项目仅是测试项目，并不完善，只实现了需要使用的基本功能，并且只提供了使用shiro模块的代码。楼主新人第一次写，如有问题希望能提出来，由衷的感谢。
首先是pom.xml：
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.0</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.0</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-ehcache</artifactId> <version>1.2.0</version> </dependency>
以下是web.xml配置：
<filter> <!-- filter-name需要和shiro的过滤器id一致 --> <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>
以下是shiro的配置：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- shior配置 begin --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <!-- <property name="cacheManager" ref="cacheManager" /> --> <!-- 自定义的Realm --> <property name="realm" ref="myRealm" /> </bean> <!-- 缓存 --> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> </bean> <bean id="myRealm" class="com.renai.shop.service.admin.AuthenticationRealm"> <!-- 加密 --> <!-- <property name="credentialsMatcher"> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <property name="hashAlgorithmName" value="SHA-256"/> <property name="storedCredentialsHexEncoded" value="false"/> </bean> </property> --> </bean> <!-- SecurityManager是shiro的核心，协调shiro的各个组件 --> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager" /> </bean> <!-- shiro过滤器 --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager" /> <property name="loginUrl" value="/login/gotoLogin.html" /> <property name="unauthorizedUrl" value="/unauthorized.jsp" /> <property name="filterChainDefinitions"> <value> /login/gotoLogin.html = anon /login/login.html = anon /login/** = authc /sys/** = authc <!-- /sys/add/** = authc, roles[manager] /sys/update/** = authc, roles[admin] /sys/delete/** = authc, perms[delete] --> </value> </property> </bean> </beans>
以下是自定义的Realm类：

以下是页面：
使用shiro的标签需要引用：
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>1
以下是按照登录时保存的权限显示按钮
<div class="tools">
<ul class="toolbar">
<shiro:hasPermission name="add">
<li class="click" onclick="add()">
<span><img src="${ctx}/skin/images/t01.png"></span>添加
</li>
</shiro:hasPermission>
<shiro:hasPermission name="update">
<li class="click" onclick="update()">
<span><img src="${ctx}/skin/images/t02.png"></span>修改
</li>
</shiro:hasPermission>
<shiro:hasPermission name="delete">
<li onclick="deletes()">
<span><img src="${ctx}/skin/images/t03.png"></span>删除
</li>
</shiro:hasPermission>
</ul>
</div>
以下是项目数据
