一、新建一個Maven的war工程,並在pom.xml中增長以下依賴。html
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-quartz</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>commons-collections</groupId> <artifactId>commons-collections</artifactId> <version>3.2.1</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2</version> </dependency>
二、在web.xml中增長以下內容。java
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-core.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <async-supported>true</async-supported> <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>
三、新增兩個頁面,分別爲login.jsp和index.jsp,主要用於展現登陸界面和主界面。web
login.jspspring
<%@page language="java" pageEncoding="UTF-8"%> <html> <head> <title>shiro-spring登陸頁面</title> <style>.error{color:red;}</style> </head> <body> <div class="error">${error}</div> <form action="" method="post"> 用戶名:<input name="username" type="text"> 密碼:<input name="password" type="password"> <button type="submit">登陸</button> </form> </body> </html>
index.jspapache
<%@page language="java" pageEncoding="UTF-8"%> <%@taglib prefix="shiro" uri="http://shiro.apache.org/tags"%> <html> <head> <title>shiro-spring歡迎頁面</title> </head> <body> <shiro:guest> 歡迎遊客訪問,<a href="${pageContext.request.contextPath}/login.jsp">點擊登陸</a><br/> </shiro:guest> <shiro:user> 歡迎[<shiro:principal/>]登陸,<a href="${pageContext.request.contextPath}/logout">點擊退出</a><br/> </shiro:user> </body> </html>
四、新增一個UserRealm類,用於實現用戶登陸操做的相關校驗。這裏爲了簡化,寫死了用戶名、密碼和鹽值。用戶名:admin,密碼:123456api
package org.cloud.shiro.realm; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authc.SimpleAuthenticationInfo; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; import org.apache.shiro.util.ByteSource; public class UserRealm extends AuthorizingRealm{ protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { return null; } protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { String username=(String) token.getPrincipal(); SimpleAuthenticationInfo authenticationInfo=new SimpleAuthenticationInfo(username,"123456",ByteSource.Util.bytes(username+"8d78869f470951332959580424d4bf4f"),getName()); return authenticationInfo; } }
五、新增spring-core.xml文件,主要用於shiro的配置。注意其中須要配置上面所編寫的UserRealm類。安全
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"> <!-- Realm實現 --> <bean id="userRealm" class="org.cloud.shiro.realm.UserRealm" /> <!-- 會話ID生成器 --> <bean id="sessionIdGenerator" class="org.apache.shiro.session.mgt.eis.JavaUuidSessionIdGenerator" /> <!-- 會話Cookie模板 --> <bean id="sessionIdCookie" class="org.apache.shiro.web.servlet.SimpleCookie"> <constructor-arg value="sid" /> <property name="httpOnly" value="true" /> <property name="maxAge" value="180000" /> </bean> <!-- 會話DAO --> <bean id="sessionDAO" class="org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO"> <property name="activeSessionsCacheName" value="shiro-activeSessionCache" /> <property name="sessionIdGenerator" ref="sessionIdGenerator" /> </bean> <!-- 會話驗證調度器 --> <bean id="sessionValidationScheduler" class="org.apache.shiro.session.mgt.quartz.QuartzSessionValidationScheduler"> <property name="sessionValidationInterval" value="1800000" /> <property name="sessionManager" ref="sessionManager" /> </bean> <!-- 會話管理器 --> <bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager"> <property name="globalSessionTimeout" value="1800000" /> <property name="deleteInvalidSessions" value="true" /> <property name="sessionValidationSchedulerEnabled" value="true" /> <property name="sessionValidationScheduler" ref="sessionValidationScheduler" /> <property name="sessionDAO" ref="sessionDAO" /> <property name="sessionIdCookieEnabled" value="true" /> <property name="sessionIdCookie" ref="sessionIdCookie" /> </bean> <!-- 安全管理器 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="userRealm" /> <property name="sessionManager" ref="sessionManager" /> </bean> <bean id="formAuthenticationFilter" class="org.apache.shiro.web.filter.authc.FormAuthenticationFilter"> <property name="usernameParam" value="username" /> <property name="passwordParam" value="password" /> </bean> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager" /> <property name="loginUrl" value="/login.jsp" /> <property name="successUrl" value="/index.jsp" /> <property name="filters"> <map> <entry key="authc" value-ref="formAuthenticationFilter"></entry> </map> </property> <property name="filterChainDefinitions"> <value> /login.jsp = authc /logout = logout /** = user </value> </property> </bean> <!-- Shiro生命週期處理器 --> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" /> </beans>
六、啓動項目後,訪問login.jsp後,會顯示登陸界面,輸入用戶名和密碼後,能夠進入到index.jsp頁面。固然點擊退出按鈕後,返回至登陸頁面中。若是未登陸系統,在地址欄中直接訪問index.jsp是會被返回至登陸頁面中的。session
到此,一個簡單的shiro示例就搭建完成,你們能夠根據項目的實際須要擴展內容。本文主要簡單列舉了一下shiro的示例,主要爲shiro的首次學習者作一個開場示例,若要深刻掌握shiro,還需本身多學習,多實踐。app
