官方文档:http://shiro.apache.org/spring.html
要求:实现用户登录功能 (与前几章讲的一样,只不过这里整合到了Spring框架中,可以对比来看)
一、新建个maven项目
二、将需要的依赖包贴到pom中
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- 添加Servlet支持 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.1</version> </dependency> <!-- 添加jtl支持 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 添加Spring支持 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.1.7.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <!-- 添加日志支持 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- 添加mybatis支持 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!-- jdbc驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.37</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.12</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.4</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.4</version> </dependency> </dependencies>
三、src/main/java新建dao entity controller realm service service.impl
1、entity.User.java
package com.guo.entity; public class User { private Integer id; private String userName; private String password; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
2、dao.UserDao.java
package com.guo.dao; import java.util.Set; import com.guo.entity.User; public interface UserDao { /** * 通过用户名查询用户 * @param userName * @return */ public User getByUserName(String userName); /** * 通过用户名查询角色信息 * @param userName * @return */ public Set<String> getRoles(String userName); /** * 通过用户名查询权限信息 * @param userName * @return */ public Set<String> getPermissions(String userName); }
3、service.UserService.java
package com.guo.service; import java.util.Set; import com.guo.entity.User; public interface UserService { /** * 通过用户名查询用户 * @param userName * @return */ public User getByUserName(String userName); /** * 通过用户名查询角色信息 * @param userName * @return */ public Set<String> getRoles(String userName); /** * 通过用户名查询权限信息 * @param userName * @return */ public Set<String> getPermissions(String userName); }
4、serviceimpl.UserServiceImpl
package com.guo.service.impl; import java.util.Set; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.guo.dao.UserDao; import com.guo.entity.User; import com.guo.service.UserService; @Service("userService") public class UserServiceImpl implements UserService{ @Resource private UserDao userDao; public User getByUserName(String userName) { return userDao.getByUserName(userName); } public Set<String> getRoles(String userName) { return userDao.getRoles(userName); } public Set<String> getPermissions(String userName) { return userDao.getPermissions(userName); } }
5、controller.UserController.java
package com.guo.controller; import javax.servlet.http.HttpServletRequest; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.session.Session; import org.apache.shiro.subject.Subject; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.guo.entity.User; /** * 用户Controller层 * @author Administrator * */ @Controller @RequestMapping("/user") public class UserController { /** * 用户登录 * @param user * @param request * @return */ @RequestMapping("/login") public String login(User user,HttpServletRequest request){ Subject subject=SecurityUtils.getSubject(); UsernamePasswordToken token=new UsernamePasswordToken(user.getUserName(), user.getPassword()); try{ subject.login(token); Session session=subject.getSession(); System.out.println("sessionId:"+session.getId()); System.out.println("sessionHost:"+session.getHost()); System.out.println("sessionTimeout:"+session.getTimeout()); session.setAttribute("info", "session的数据"); return "redirect:/success.jsp"; }catch(Exception e){ e.printStackTrace(); request.setAttribute("user", user); request.setAttribute("errorMsg", "用户名或密码错误!"); return "index"; } } }
6、realm.MyRealm.java
package com.guo.realm; import javax.annotation.Resource; 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.authz.SimpleAuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; import com.guo.entity.User; import com.guo.service.UserService; public class MyRealm extends AuthorizingRealm{ @Resource private UserService userService; /** * 为当限前登录的用户授予角色和权 */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { String userName=(String)principals.getPrimaryPrincipal(); SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo(); authorizationInfo.setRoles(userService.getRoles(userName)); authorizationInfo.setStringPermissions(userService.getPermissions(userName)); return authorizationInfo; } /** * 验证当前登录的用户 */ @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { String userName=(String)token.getPrincipal(); User user=userService.getByUserName(userName); if(user!=null){ AuthenticationInfo authcInfo=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx"); return authcInfo; }else{ return null; } } }
四、在src/main/resource下建mappers.xml映射包(一些SSM配置文件也放到src/main/resource下)
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.guo.dao.UserDao"> <resultMap type="User" id="UserResult"> <result property="id" column="id"/> <result property="userName" column="userName"/> <result property="password" column="password"/> </resultMap> <select id="getByUserName" parameterType="String" resultMap="UserResult"> select * from t_user where userName=#{userName} </select> <select id="getRoles" parameterType="String" resultType="String"> select r.roleName from t_user u,t_role r where u.roleId=r.id and u.userName=#{userName} </select> <select id="getPermissions" parameterType="String" resultType="String"> select p.permissionName from t_user u,t_role r,t_permission p where u.roleId=r.id and p.roleId=r.id and u.userName=#{userName} </select> </mapper>
五、Shiro.ini配置文件 被放到Spring的配置文件applicationContext.xml
<?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:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> <!-- 自动扫描 --> <context:component-scan base-package="com.guo.service" /> <!-- 配置数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/db_shiro"/> <property name="username" value="root"/> <property name="password" value="123456"/> </bean> <!-- 配置mybatis的sqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mappers.xml文件 --> <property name="mapperLocations" value="classpath:com/guo/mappers/*.xml"></property> <!-- mybatis配置文件 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean> <!-- DAO接口所在包名,Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.guo.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 自定义Realm --> <bean id="myRealm" class="com.guo.realm.MyRealm"/> <!-- 安全管理器 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="myRealm"/> </bean> <!-- Shiro过滤器 --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <!-- Shiro的核心安全接口,这个属性是必须的 --> <property name="securityManager" ref="securityManager"/> <!-- 身份认证失败,则跳转到登录页面的配置 --> <property name="loginUrl" value="/index.jsp"/> <!-- 权限认证失败,则跳转到指定页面 --> <property name="unauthorizedUrl" value="/unauthor.jsp"/> <!-- Shiro连接约束配置,即过滤链的定义 --> <property name="filterChainDefinitions"> <value> /login=anon /admin*=authc /student=roles[teacher] /teacher=perms["user:create"] </value> </property> </bean> <!-- 保证实现了Shiro内部lifecycle函数的bean执行 --> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <!-- 开启Shiro注解 --> <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> <!-- 配置事务通知属性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- 定义事务传播属性 --> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="new*" propagation="REQUIRED" /> <tx:method name="set*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="change*" propagation="REQUIRED" /> <tx:method name="check*" propagation="REQUIRED" /> <tx:method name="get*" propagation="REQUIRED" read-only="true" /> <tx:method name="find*" propagation="REQUIRED" read-only="true" /> <tx:method name="load*" propagation="REQUIRED" read-only="true" /> <tx:method name="*" propagation="REQUIRED" read-only="true" /> </tx:attributes> </tx:advice> <!-- 配置事务切面 --> <aop:config> <aop:pointcut id="serviceOperation" expression="execution(* com.guo.service.*.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" /> </aop:config> </beans>
