Apache Shiro权限框架在SpringMVC+Hibernate中的应用

2023-07-20 11:01:28

在做网站开发中，用户权限必须要考虑的，权限这个东西很重要，它规定了用户在使用中能进行哪些操作，和不能进行哪些操作；我们完全可以使用过滤器来进行权限的操作，但是有了权限框架之后，使用起来会非常的方便，一般在公司里面做网站开发常用的权限框架有Spring的Security框架，和Apache的Shiro框架；Spring Security框架在使用上相比Shiro来说要更复杂一些，并且它限制了数据库该怎么去建表，只有按它的要求去建表，才能达到你想要的效果。下面我主要介绍一下Shiro框架的使用，由于本人也是初学者，所写难免会有些不合理的地方，望各位指正；

使用Apache Shiro框架的步骤：

1.导入相应的jar包，我使用的是maven来管理的，pom.xml配置如下：

<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

2.在web.xml中进行配置：

<?xml version="1.0"encoding="UTF-8"?>

<web-app version="2.5"

xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

 <display-name>Archetype Created Web Application</display-name>

 <!-- OpenSessionInView -->

<filter>

<filter-name>opensessioninview</filter-name>

<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>opensessioninview</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

 <!-- SpringMVC*控制器 -->

<servlet>

<servlet-name>mvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>mvc</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

 <!-- Spring监听器 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext*.xml</param-value>

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

 <!-- Shiro配置 -->

<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>

</web-app>

3.使用SpringMVC：在/WEB-INF/路径下配置springmvc-servlet.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:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

<!-- 自动扫描 -->

<context:component-scan base-package="com.kaishengit.controller">

<context:include-filter type="annotation"expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<mvc:annotation-driven/>

<!-- 静态资源访问 -->

<mvc:resources location="/static/"mapping="/static/**"/>

<!-- 视图解析器 -->

<bean id="viewResolver"class="org.springframework.web.servlet.view.UrlBasedViewResolver">

<property name="viewClass"value="org.springframework.web.servlet.view.JstlView"/>

<property name="prefix"value="/WEB-INF/views/"/>

<property name="suffix"value=".jsp"/>

</bean>

<!-- 文件上传解析器 -->

<bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<!-- 配置最大上传文件的大小 -->

<property name="maxUploadSize"value="1000000"/>

</bean>

<!-- 拦截器 -->

<mvc:interceptors>

<mvc:interceptor>

<mvc:mapping path="/**"/>

<bean class="com.kaishengit.controller.MyInterceptor">

<property name="excluedUrls">

<list>

<value>/home</value>

</list>

</property>

</bean>

</mvc:interceptor>

</mvc:interceptors>

<!-- 异常 -->

<bean id="handlerExceptionResolver"class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">

<property name="exceptionMappings">

<props>

<prop key="com.kaishengit.exception.AuthorizationException">redirect:/home</prop>

</props>

</property>

</bean>

</beans>

4.配置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:aop="http://www.springframework.org/schema/aop"

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.xsd

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 自动扫描所有的注解，排除掉controller不扫描 -->

<context:component-scan base-package="com.kaishengit">

<context:exclude-filter type="annotation"expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<!-- 加载ClassPath中的properties文件 -->

<context:property-placeholder location="classpath:jdbc.properties"/>

<!-- 基于Hibernate的事务管理器 -->

<bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager">

<property name="sessionFactory"ref="sessionFactory"></property>

</bean>

<!-- 配置数据源 -->

<bean id="dataSource"class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close">

<property name="driverClassName"value="${jdbc.driver}"/>

<property name="url"value="${jdbc.url}"/>

<property name="username"value="${jdbc.username}"/>

<property name="password"value="${jdbc.password}"/>

</bean>

<!-- 基于注解 -->

<tx:annotation-driven transaction-manager="transactionManager"/>

<!-- SessionFactory -->

<bean id="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<property name="dataSource"ref="dataSource"/>

<!-- 实体类pojo所在的包 -->

<property name="packagesToScan"value="com.kaishengit.pojo"/>

<property name="hibernateProperties">

<props>

<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

<prop key="hibernate.show_sql">true</prop>

<prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>

</props>

</property>

</bean>

</beans>

5.将配置在applicationContext.xml中的shiro独立出来，新建applicationContext-shiro.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:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<bean id="securityManager"class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">

<property name="realm"ref="myShiro"/>

<property name="cacheManager"ref="cacheManager"/>

</bean>

<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"/>

<property name="unauthorizedUrl"value="/403"/>

<property name="filterChainDefinitions">

<value>

<!--静态资源直接通过-->

/static/** =anon

<!--只有admin角色才能访问/user/save-->

/user/save =roles[admin]

<!--具有user:add权限的用户可以访问/user/save-->

<!--/user/save =perms[user:add]-->

<!--所有的请求都要通过验证-->

/** = authc

</value>

</property>

</bean>

<bean id="cacheManager"

class="org.apache.shiro.cache.MemoryConstrainedCacheManager"/>

<bean id="lifecycleBeanPostProcessor"

class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

</beans>

6.实现MyRealm:继承AuthorizingRealm,并重写认证授权方法

package com.kaishengit.service;

import java.util.List;

import javax.inject.Inject;

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.authc.UsernamePasswordToken;

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.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import com.kaishengit.pojo.Role;

import com.kaishengit.pojo.User;

@Service

@Transactional

public class MyRealm extends AuthorizingRealm{

@Inject

private UserService userService;

/**

 * 权限认证

*/

@Override

protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

//获取登录的用户名

String loginName=(String) principalCollection.fromRealm(getName()).iterator().next();

User user=userService.findByName(loginName);

if(user!=null){

SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();

//登录的用户有多少个角色

info.setRoles(user.getRolesName());

List<Role> roleList=user.getRoleList();

for(Role role:roleList){

//角色有多少个权限

info.addStringPermissions(role.getPermissionNames());

}

return info;

}

return null;

}

/**

 * 登录认证

*/

@Override

protected AuthenticationInfo doGetAuthenticationInfo(

AuthenticationToken authenticationToken) throws AuthenticationException {

UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;

User user = userService.findByName(token.getUsername());

if(user != null) {

return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName());

}

return null;

}

}

7.HomeController.java

package com.kaishengit.controller;

import org.apache.shiro.SecurityUtils;

import org.apache.shiro.authc.AuthenticationException;

import org.apache.shiro.authc.UsernamePasswordToken;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import com.kaishengit.pojo.User;

@Controller

public class HomeController {

@RequestMapping(value="/login",method=RequestMethod.GET)

public String loginForm(){

return"/login";

}

@RequestMapping(value="/login",method=RequestMethod.POST)

public String login(User user,RedirectAttributes redirectAttributes){

try {

SecurityUtils.getSubject().login(new UsernamePasswordToken(user.getUsername(), user.getPassword()));

return"redirect:/user";

} catch (AuthenticationException e) {

redirectAttributes.addFlashAttribute("message","用户名或密码错误");

return"redirect:/login";

}

}

@RequestMapping(value="/logout",method=RequestMethod.GET)

public String logout(RedirectAttributes redirectAttributes ){

SecurityUtils.getSubject().logout();

redirectAttributes.addFlashAttribute("message","您已安全退出");

return"redirect:/login";

}

}

8.在jsp中使用Shiro标签库：

<%@ taglib prefix="shiro"uri="http://shiro.apache.org/tags"%>

<html>

<head>

</head>

<body>

<h2>welcome!<shiro:principal/></h2>

<shiro:hasRole name="manager">

</shiro:hasRole>

</body>

</html>

9.数据库中建表，E-R图如下：
