第八章：Shiro和Spring的集成——深入浅出学Shiro细粒度权限开发框架

Standalone Applications

nShiro 应用程序需要一个具有单例SecurityManager 实例的应用程序。请注意，这不会是一个静态的单例，但应该只有一个应用程序能够使用的实例，无论它是否是静态单例的。

n在Spring 应用程序中启用应用程序单例SecurityManager的最简单配置：

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">

<property name="staticMethod" value="org.apache.shiro.SecurityUtils.setSecurityManager"/>

<property name="arguments" ref="securityManager"/>

</bean>

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

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

</bean>

<bean id="myRealm" class="org.apache.shiro.realm.text.IniRealm">

<property name="resourcePath" value="D:/wp/src/TestShiro.ini"></property>

</bean>

Wb应用

n在web.xml中

<filter>

<filter-name>shiroFilter</filter-name>

<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

<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>

n在spring的applicationContext.xml 文件中，定义web 支持的SecurityManager 和'shiroFilter' bean 将会被web.xml 引用

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">

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

<!—以下为可选配置，请按照实际项目需要进行配置-->

<property name="loginUrl" value="/login.jsp"/>

<property name="unauthorizedUrl" value="/unauthorized.jsp"/>

<!– filters属性也是可选的，用来声明一些可以在filterChainDefinitions里面使用的filter。如果你声明的filter名称是shiro默认有的，那么将会覆盖默认的filter -->

<property name="filters">

<util:map>

<!– 比如：这个filter是shiro里面有的，那么自定义的filter将会覆盖默认的-->

<entry key="authc" value-ref="formAuthenticationFilter"/>

<!– 比如：这个filter是项目新加的filter-->

<entry key="jCaptchaValidate" value-ref="jCaptchaValidateFilter"/>

</util:map>

</property>

<property name="filterChainDefinitions">

<value>

<!— 这里配置urls，对不同的url配置需要经过的filter-->

/jcaptcha* = anon

/logout = logout

/login = jCaptchaValidate,authc

</value>

</property>

</bean>

<!--替换默认的form 验证过滤器-->

<bean id="formAuthenticationFilter" class="cn.javass.CustomFormAuthenticationFilter">

......

</bean>

<!—然后就是SecurityManger、Realms等-->

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

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

</bean>

<bean id="myRealm" class="org.apache.shiro.realm.text.IniRealm">

<property name="resourcePath" value="D:/wp/src/TestShiro.ini"></property>

</bean>

n开启注解

<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"

depends-on="lifecycleBeanPostProcessor" >

<property name="proxyTargetClass" value="true"/>

</bean>

<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

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

</bean>

和Struts2+Spring3的集成

n构建一个动态web工程，然后把包加好，web.xml的配置如下：

<?xml version="1.0" encoding="ISO-8859-1"?>

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

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

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
metadata-complete="true" version="3.0">

<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>

<filter>

<filter-name>shiroFilter</filter-name>

<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

<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>

<filter>

<filter-name>struts2</filter-name>

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

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

</filter-mapping>

</web-app>

nStruts2的配置比较简单：

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

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

<constant name="struts.devMode" value="true"/>

<constant name="struts.locale" value="zh_CN"/>

<constant name="struts.i18n.encoding" value="utf-8"/>

</struts>

nSpring的配置文件基本就是前面讲到的，合在一起了，示例如下：

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">

<aop:aspectj-autoproxy proxy-target-class="true"/>

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

<context:component-scan base-package="cn.javass"></context:component-scan>

<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"

depends-on="lifecycleBeanPostProcessor" >

<property name="proxyTargetClass" value="true"/> </bean>

<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

<property name="securityManager" ref="securityManager" /> </bean>

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">

<property name="staticMethod" value="org.apache.shiro.SecurityUtils.setSecurityManager"/>

<property name="arguments" ref="securityManager"/>

</bean>

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">

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

<property name="filterChainDefinitions">

<value>

/userAction!toList.action = roles[role1]

</value>

</property>

</bean>

<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />

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

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

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

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

</bean>

<bean id="sessionManager" class="org.apache.shiro.session.mgt.DefaultSessionManager"></bean>

<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager" />

<bean id="myRealm" class="org.apache.shiro.realm.text.IniRealm">

<property name="resourcePath" value="D:/shiroweb/src/TestShiro.ini"></property>

</bean>

</beans>

n对应的TestShiro.int做了足够的简化，示例如下：

[users]

javass=cc,role1

[roles]

role1 = p1,p2

n写一个LoginAction，示例如下：

@Action(

value="/login",

results={

@Result(name = "toList", location = "/list.jsp"),

@Result(name = "success", location = "/ok.jsp")})

public class LoginAction extends ActionSupport{

private String userId = "";

private String pwd = "";

//getter setter

public String execute(){

UsernamePasswordToken token = new UsernamePasswordToken(userId,pwd);

token.setRememberMe(true);

Subject currentUser = SecurityUtils.getSubject();

currentUser.login(token);

System.out.println(currentUser.getPrincipal()+"====has r1 === "+currentUser.hasRole("role1"));

return this.SUCCESS;

}

}

n写一个UserAction进行权限测试，示例如下：

@Action(

value="/user",

results={

@Result(name = "toList", location = "/list.jsp"),

@Result(name = "success", location = "/ok.jsp")

}

)

public class UserAction extends ActionSupport{

@RequiresPermissions({"p1"})

public String execute(){

Subject currentUser = SecurityUtils.getSubject();

System.out.println("now user===="+currentUser.getPrincipal()+" ,role=="+currentUser.hasRole("role1")+" , p=="+currentUser.isPermitted("p1"));

return "toList";

}

}

n和Struts2集成的时候，如果使用注解的方式进行权限判断，而struts2又使用spring的依赖注入逻辑层的对象的时候，是存在bug的，可能会导致取不到注入的对象。这个bug是struts2的，主要是都是使用的aop，有一些冲突。需要修正，可以加入我们修正的代码包。同时要注意：需要使用getter/setter来注入，不要使用属性的方式。

和 SpringMVC+Spring3 的集成

n构建一个动态web工程，然后把包加好，web.xml的配置如下：

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

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

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

</init-param>

</filter>

<filter-mapping>

<filter-name>shiroFilter</filter-name>

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

</filter-mapping>

<servlet>

<servlet-name>springmvc</servlet-name>

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

<init-param>

<param-value>classpath:spring-servlet-config.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

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

</servlet-mapping>

</web-app>

n对应的TestShiro.ini跟前面struts2集成是一样的

nSpring的配置文件基本跟前面那个差不多，只是有部分配置移到springmvc的配置文件中了，示例如下：

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

n对应的TestShiro.ini跟前面struts2集成是一样的

nSpring的配置文件基本跟前面那个差不多，只是有部分配置移到springmvc的配置文件中了，示例如下：

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">

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

<property name="filterChainDefinitions">

<value>

</value>

</property>

<property name="resourcePath" value="D:/newlesson/shiro/webwp/mvc/src/TestShiro.ini"></property>

</bean>

</beans>

nSpringmvc的配置文件，示例如下：

<?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"

<property name="staticMethod" value="org.apache.shiro.SecurityUtils.setSecurityManager"/>

<property name="arguments" ref="securityManager"/>

</bean>

</beans>

n简单的HelloWorldController，示例如下：

@Controller

public class HelloWorldController {

@Autowired

private MyService ms = null;

@RequestMapping("/login")

public String login(@RequestParam("username") String username,@RequestParam("password") String password) {

System.out.println("user==" +username+" , pwd=="+password);

UsernamePasswordToken token = new UsernamePasswordToken(username,password);

token.setRememberMe(true);

Subject currentUser = SecurityUtils.getSubject();

currentUser.login(token);

System.out.println(currentUser.getPrincipal()+"====has r1 === "+currentUser.hasRole("r1")+" , isau=="+currentUser.isAuthenticated());

return "login";

}

@RequestMapping("/h3")

@RequiresAuthentication

@RequiresPermissions({"p1"})

public String h3(@ModelAttribute("nn")String nn ) {

ms.doService();

System.out.println("nn=="+SecurityUtils.getSubject().isAuthenticated());

return "ok";

}

}

n对应的MyService非常简单，示例如下：

@Service

public class MyService {

public void doService(){

System.out.println("now do Service");

}

}

n再来一个Login.jsp，就可以测试了，示例如下：

<form action="/shirolessonmvc/login" method="post">

<table>

<tr>

<td>用户名：</td>

<td><input type="text" name="username"></input></td>

</tr>

<tr>

<td>密码：</td>

<td><input type="password" name="password"></input></td>

</tr>

<tr>

<td>记住我</td>

<td><input type="checkbox" name="rememberMe" checked/></td>

<td><input type="submit"></td>

</tr>

</table> </form>
