    struts2-core-2.3.15.3.jar
    struts2-spring-plugin-2.3.15.3.jar
    xwork-core-2.3.15.3.jar

    二、配置web.xml 必不可少

    [html] view plain copy
    1. <?xml version="1.0" encoding="UTF-8"?>  
    2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  
    3.   <!-- 1.配置springIOC容器监听器 -->  
    4.     <context-param>  
    5.         <param-name>contextConfigLocation</param-name>  
    6.         <param-value>classpath:application.xml</param-value>  
    7.     </context-param>  
    8.   
    9.     <!-- Bootstraps the root web application context before servlet initialization -->  
    10.     <listener>  
    11.         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    12.     </listener>  
    13.     
    14.   <!--2.配置shiro过滤器  -->  
    15.    <filter>  
    16.         <filter-name>shiroFilter</filter-name>  
    17.         <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>  
    18.         <init-param>  
    19.             <param-name>targetFilterLifecycle</param-name>  
    20.             <param-value>true</param-value>  
    21.         </init-param>  
    22.     </filter>  
    23.     <filter-mapping>  
    24.         <filter-name>shiroFilter</filter-name>  
    25.         <url-pattern>/*</url-pattern>  
    26.     </filter-mapping>  
    27.       
    28.     <!--3.配置struts2过滤器  -->  
    29.     <filter>  
    30.         <filter-name>struts2</filter-name>  
    31.         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  
    32.     </filter>  
    33.     <filter-mapping>  
    34.         <filter-name>struts2</filter-name>  
    35.         <url-pattern>/*</url-pattern>  
    36.     </filter-mapping>    
    37.     
    38. </web-app>  

    三、配置spring配置文件application.xml更为重要!

    [html] view plain copy
    1. <?xml version="1.0" encoding="UTF-8"?>  
    2. <beans xmlns="http://www.springframework.org/schema/beans"  
    3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    4.     xmlns:context="http://www.springframework.org/schema/context"  
    5.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
    6.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">  
    7.   
    8.     <!-- 1.配置要扫描的包 -->  
    9.     <context:component-scan base-package="com.tan.shiro"></context:component-scan>  
    10.       
    11.     <!--2.配置CacheManager实例:管理Shiro相关缓存操作  -->  
    12.     <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">   
    13.         <property name="cacheManagerConfigFile" value="classpath:ehcache-shiro.xml"></property>  
    14.     </bean>  
    15.       
    16.     <!--3.配置realm实例,实际的认证和授权都是由Realm实例来完成的!  -->  
    17.     <bean id="myRealm" class="com.tan.shiro.realm.MyRealm"></bean>  
    18.   
    19.     <!-- 4.配置 SecurityManager 实例. SecurityManager 是 Shiro 最核心的组件 -->  
    20.     <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">  
    21.         <property name="cacheManager" ref="cacheManager"/>  
    22.         <property name="realm" ref="myRealm"/>  
    23.     </bean>  
    24.       
    25.     <!--5.配置bean的后置处理器来自动调用Shiro中的bean的init和destroy方法。  -->  
    26.     <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"></bean>  
    27.       
    28.       
    29.     <!--6.配置使shiro注解起作用的bean,需要放在 lifecycleBeanPostProcessor后面 -->  
    30.     <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"></bean>      
    31.     <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">  
    32.         <property name="securityManager" ref="securityManager"></property>  
    33.     </bean>  
    34.       
    35.     <!--  
    36.         7.配置哪些页面需要被拦截,以及访问这些页面所需的权限 。  
    37.         该bean中的id 属性值必须和 web.xml 文件中配置的 filter 的 filter-name 值一致  
    38.     -->  
    39.     <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">  
    40.         <property name="securityManager" ref="securityManager"></property>  
    41.       
    42.         <!--①配置登陆页面  -->  
    43.         <property name="loginUrl" value="/login.jsp"></property>  
    44.         <property name="successUrl" value="/list.jsp"></property>  
    45.         <property name="unauthorizedUrl" value="/unauthorize.jsp"></property>  
    46.         <!--②配置需要被拦截的资源 以及访问权限 -->  
    47.         <property name="filterChainDefinitions">  
    48.             <value>  
    49.                 <!-- anon: 表示匿名的, 即任何人都可以访问 -->  
    50.                 /login.jsp=anon  
    51.                 /login=anon  
    52.                 /logout=logout  
    53.                   
    54.                 <!--③设置访问具体资源的权限  -->  
    55.                 /admin.jsp=roles[admin]  
    56.                 /user.jsp=roles[user]  
    57.                   
    58.                 <!-- authc 表示必须经过认证之后才可以访问的页面 -->  
    59.                 /**=authc  
    60.             </value>  
    61.         </property>  
    62.     </bean>  
    63. </beans>  


    四、新建自定义Realm来实现自定义的认证和授权

    [java] view plain copy
    1. package com.tan.shiro.realm;  
    2.   
    3. import java.io.Serializable;  
    4. import java.util.HashSet;  
    5. import java.util.Set;  
    6.   
    7. import org.apache.shiro.authc.AuthenticationException;  
    8. import org.apache.shiro.authc.AuthenticationInfo;  
    9. import org.apache.shiro.authc.AuthenticationToken;  
    10. import org.apache.shiro.authc.IncorrectCredentialsException;  
    11. import org.apache.shiro.authc.LockedAccountException;  
    12. import org.apache.shiro.authc.SimpleAuthenticationInfo;  
    13. import org.apache.shiro.authc.UnknownAccountException;  
    14. import org.apache.shiro.authc.UsernamePasswordToken;  
    15. import org.apache.shiro.authz.AuthorizationInfo;  
    16. import org.apache.shiro.authz.SimpleAuthorizationInfo;  
    17. import org.apache.shiro.realm.AuthorizingRealm;  
    18. import org.apache.shiro.subject.PrincipalCollection;  
    19.   
    20. public class MyRealm extends AuthorizingRealm implements Serializable {  
    21.     private static final long serialVersionUID = 1L;  
    22.   
    23.     //一、认证 (自定义认证)  
    24.     @Override  
    25.     protected AuthenticationInfo doGetAuthenticationInfo(  
    26.             AuthenticationToken arg0) throws AuthenticationException {  
    27.         //强转为UsernamePasswordToken类型  
    28.         UsernamePasswordToken token=(UsernamePasswordToken)arg0;   
    29.           
    30.         //获取用户名和密码(密码要转为字符串类型)  
    31.         String username = token.getUsername();  
    32.         String password = new String(token.getPassword());  
    33.           
    34.         //测试一下,看是否得到了用户名和密码  
    35.          System.out.println("username: " + username + ", password: " + password);  
    36.           
    37.         //模拟查询数据库进行登录操作  
    38.          if("a".equals(username)){  
    39.              throw new UnknownAccountException("没有这个账号");   
    40.          }  
    41.          if("a".equals(password)){  
    42.              throw new IncorrectCredentialsException("密码错误");   
    43.          }  
    44.          if("b".equals(username)){  
    45.              throw new LockedAccountException("账号被锁定!");   
    46.          }  
    47.          //利用新建的类来创建对象  
    48.          ShiroUser user=new ShiroUser();  
    49.          user.setUsername(username); //将页面中的username值设置进去  
    50.            
    51.          //模拟设置权限部分:要分别来判断  
    52.         if("admin".equals(username)){  
    53.             //如果用户名为:admin,则为其增加2个角色 admin和user  
    54.             user.getRoles().add("admin");  
    55.             user.getRoles().add("user");  
    56.         }else if("user".equals(username)){  
    57.             //如果用户名为:user,则为其增加user角色  
    58.             user.getRoles().add("user");  
    59.         }  
    60.         return new SimpleAuthenticationInfo(user, password,getName());  
    61.     }  
    62.       
    63.     //二、授权(自定义)  
    64.      @Override  
    65.         protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection arg0) {  
    66.         //arg0.getPrimaryPrincipal(): 实际上是在认证时返回的 SimpleAuthenticationInfo 的第一个参数!  
    67.             Object principal = arg0.getPrimaryPrincipal();  
    68.             ShiroUser user = (ShiroUser) principal;  
    69.             SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(user.getRoles());  
    70.             return info;  
    71.         }  
    72.        
    73.   
    74.     //新建一个类定义用户角色和权限  
    75.     class ShiroUser implements Serializable{  
    76.         private static final long serialVersionUID = 1L;  
    77.         private String username;  
    78.         private Set<String>roles=new HashSet<String>();  
    79.           
    80.         public String getUsername() {  
    81.             return username;  
    82.         }  
    83.         public void setUsername(String username) {  
    84.             this.username = username;  
    85.         }  
    86.         public Set<String> getRoles() {  
    87.             return roles;  
    88.         }  
    89.         public void setRoles(Set<String> roles) {  
    90.             this.roles = roles;  
    91.         }  
    92.     }  
    93.       
    94. }  


    五、利用Struts2新建Controller来控制登陆

    [java] view plain copy
    1. package com.tan.shiro.action;  
    2.   
    3. import org.apache.shiro.authc.AuthenticationException;  
    4. import org.apache.shiro.SecurityUtils;  
    5. import org.apache.shiro.authc.IncorrectCredentialsException;  
    6. import org.apache.shiro.authc.LockedAccountException;  
    7. import org.apache.shiro.authc.UnknownAccountException;  
    8. import org.apache.shiro.authc.UsernamePasswordToken;  
    9. import org.apache.shiro.subject.Subject;  
    10. import org.springframework.context.annotation.Scope;  
    11. import org.springframework.stereotype.Controller;  
    12. @Controller  
    13. @Scope("prototype")  
    14. public class LoginAction {  
    15.     private String username;  
    16.     private String password;  
    17.      public void setUsername(String username) {  
    18.         this.username = username;  
    19.     }  
    20.      public void setPassword(String password) {  
    21.         this.password = password;  
    22.     }  
    23.      public String login(){  
    24.          System.out.println("[login...]");  
    25.           
    26.          //1.获取当前的用户  
    27.          Subject currentUser = SecurityUtils.getSubject();  
    28.          //2.把登录信息封装为一个 UsernamePasswordToken 对象  
    29.          UsernamePasswordToken token=new UsernamePasswordToken(this.username,this.password);  
    30.          //3.设置"记住我"功能  
    31.          token.setRememberMe(true);  
    32.             try {  
    33.                 // *登录操作!  
    34.                 currentUser.login(token);  
    35.             } catch (UnknownAccountException uae) {  
    36.                 System.out.println("用户名不存在: " + uae);  
    37.                 return "input";  
    38.             } catch (IncorrectCredentialsException ice) {  
    39.                 System.out.println("用户名存在,但密码和用户名不匹配: " + ice);  
    40.                 return "input";  
    41.             } catch (LockedAccountException lae) {  
    42.                 System.out.println("用户被锁定: " + lae);  
    43.                 return "input";  
    44.             } catch (AuthenticationException ae) {  
    45.                 System.out.println("其他异常: " + ae);  
    46.                 return "input";  
    47.             }  
    48.    
    49.          return "success";  
    50.      }  
    51. }  

    六、配置struts.xml 来渲染视图

    [html] view plain copy
    1. <?xml version="1.0" encoding="UTF-8"?>  
    2. <!DOCTYPE struts PUBLIC  
    3.     "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"  
    4.     "http://struts.apache.org/dtds/struts-2.3.dtd">  
    5. <struts>  
    6.   
    7.     <constant name="struts.enable.DynamicMethodInvocation" value="false" />  
    8.     <constant name="struts.devMode" value="true" />  
    9.   
    10.     <package name="default" namespace="/" extends="struts-default">  
    11.           
    12.         <action name="login" class="loginAction" method="login">  
    13.             <result>/list.jsp</result>  
    14.             <result name="input">/login.jsp</result>  
    15.         </action>  
    16.         <action name="page" class="loginAction" method="getPage">  
    17.             <result name="success"></result>  
    18.         </action>  
    19.           
    20.     </package>  
    21.   
    22. </struts>  


    七、在webContent下新建几个简单的跳转页面 


         admin.jsp  | list.jsp  |  login.jsp  |user.jsp | unauthorize.jsp


    【补充】

      ehcache-shiro.xml文件可以从源码中获取,为了大家方便还是粘出来O(∩_∩)O~

    [html] view plain copy
    1. <ehcache>  
    2.     <diskStore path="java.io.tmpdir/shiro-spring-sample"/>  
    3.     <defaultCache  
    4.             maxElementsInMemory="10000"  
    5.             eternal="false"  
    6.             timeToIdleSeconds="120"  
    7.             timeToLiveSeconds="120"  
    8.             overflowToDisk="false"  
    9.             diskPersistent="false"  
    10.             diskExpiryThreadIntervalSeconds="120"  
    11.             />  
    12.   
    13.     <cache name="shiro-activeSessionCache"  
    14.            maxElementsInMemory="10000"  
    15.            eternal="true"  
    16.            overflowToDisk="true"  
    17.            diskPersistent="true"  
    18.            diskExpiryThreadIntervalSeconds="600"/>  
    19.   
    20.     <cache name="org.apache.shiro.realm.SimpleAccountRealm.authorization"  
    21.            maxElementsInMemory="100"  
    22.            eternal="false"  
    23.            timeToLiveSeconds="600"  
    24.            overflowToDisk="false"/>  
    25. </ehcache>
