1、新建一个Maven的war工程，并在pom.xml中增加如下依赖。
<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>
2、在web.xml中增加如下内容。
<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>
3、新增两个页面，分别为login.jsp和index.jsp，主要用于展示登录界面和主界面。
login.jsp
<%@page language="java" pageEncoding="UTF-8"%>
<html>
<head>
<title>shiro-spring登录页面</title>
<style>.error{color:red;}</style>
</head>
<body>
<div class="error">${error}</div>
<form action="" method="post">
用户名：<input name="username" type="text"> 密码：<input
name="password" type="password">
<button type="submit">登录</button>
</form>
</body>
</html>
index.jsp
<%@page language="java" pageEncoding="UTF-8"%>
<%@taglib prefix="shiro" uri="http://shiro.apache.org/tags"%>
<html>
<head>
<title>shiro-spring欢迎页面</title>
</head>
<body>
<shiro:guest>
欢迎游客访问，<a href="${pageContext.request.contextPath}/login.jsp">点击登录</a><br/>
</shiro:guest>
<shiro:user>
欢迎[<shiro:principal/>]登录，<a href="${pageContext.request.contextPath}/logout">点击退出</a><br/>
</shiro:user>
</body>
</html>
4、新增一个UserRealm类，用于实现用户登录操作的相关校验。这里为了简化，写死了用户名、密码和盐值。用户名：admin，密码：123456
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;
}
}
5、新增spring-core.xml文件，主要用于shiro的配置。注意其中需要配置上面所编写的UserRealm类。
<?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实现 --> <bean id="userRealm" class="org.cloud.shiro.realm.UserRealm" /> <!-- 会话ID生成器 --> <bean id="sessionIdGenerator" class="org.apache.shiro.session.mgt.eis.JavaUuidSessionIdGenerator" /> <!-- 会话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> <!-- 会话DAO --> <bean id="sessionDAO" class="org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO"> <property name="activeSessionsCacheName" value="shiro-activeSessionCache" /> <property name="sessionIdGenerator" ref="sessionIdGenerator" /> </bean> <!-- 会话验证调度器 --> <bean id="sessionValidationScheduler" class="org.apache.shiro.session.mgt.quartz.QuartzSessionValidationScheduler"> <property name="sessionValidationInterval" value="1800000" /> <property name="sessionManager" ref="sessionManager" /> </bean> <!-- 会话管理器 --> <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生命周期处理器 --> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" /> </beans>
6、启动项目后，访问login.jsp后，会显示登录界面，输入用户名和密码后，可以进入到index.jsp页面。当然点击退出按钮后，返回至登录页面中。如果未登录系统，在地址栏中直接访问index.jsp是会被返回至登录页面中的。
到此，一个简单的shiro示例就搭建完成，大家可以根据项目的实际需要扩展内容。本文主要简单列举了一下shiro的示例，主要为shiro的首次学习者做一个开场示例，若要深入掌握shiro，还需自己多学习，多实践。
