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

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

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"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  id="WebApp_ID" version="3.0"  metadata-complete="true"> 
  <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>
  <servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
  <param-name>contextConfigLocation</param-name>
  <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>

对应的TestShiro.ini跟前面struts2集成是一样的

Spring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"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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>
  </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.web.session.mgt.DefaultWebSessionManager"></bean>

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

Springmvc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"

  <mvc:resources mapping="/static/**" location="/WEB-INF/static/" />
  <!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- -->
  <bean id="defaultViewResolver"

  <property name="viewClass"  value="org.springframework.web.servlet.view.JstlView" />
  <property name="contentType" value="text/html" />
  <property name="prefix" value="/WEB-INF/jsp/" />
  <property name="suffix" value=".jsp" />
  </bean>
  <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"

  <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>
</beans>

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";
  }
}

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");
  }
}

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>
