Spring MVC 中Apache Shiro 框架的使用步骤

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

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中央控制器 -->
<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>

Nothing is impossible
