有空学了一个简单的安全框架shiro，资料比较少，在百度和google上能搜到的中文我看过了，剩下的时间有空会研究下官网的文章和查看下源码，

 

简单的分享一些学习过程；

1，简单的一些概念上的认知

2，使用认证的基本流程

3，shiro集成spring完成简单的认证流程，已实现

    <bean id="myRealm" class="com.util.MysqlJdbcRealM"/>

1	建一个maven的web项目,引入依赖   springmvc的的依赖       <dependency>             <groupId>org.springframework</groupId>             <artifactId>spring-webmvc</artifactId>             <version>3.2.0.RELEASE</version>         </dependency> shiro跟spring集成的插件  <dependency>             <groupId>org.apache.shiro</groupId>             <artifactId>shiro-spring</artifactId>             <version>1.2.3</version>         </dependency>
2	配置web.xml 指出spring容器的配置文件位置 <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath*:context_config.xml</param-value>     </context-param> 指出spring在web容器中的代号     <context-param>         <param-name>webAppRootKey</param-name>         <param-value>wechatSystem</param-value>     </context-param> 初始化spring的容器     <listener>         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener> spring mvc的分发器     <servlet>           <servlet-name>admin</servlet-name>           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>         <init-param>             <param-name>contextConfigLocation</param-name>             <param-value>classpath*:admin-dispatcher-servlet.xml</param-value>         </init-param>         <load-on-startup>1</load-on-startup>      </servlet>      <servlet-mapping>           <servlet-name>admin</servlet-name>           <url-pattern>/</url-pattern>      </servlet-mapping> spring跟shiro集成的过滤代理  <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>/admin/*</url-pattern>     </filter-mapping>     <!-- 字符过滤，保存中文的时候用到 -->     <filter>         <filter-name>characterEncoding</filter-name>         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>         <init-param>             <param-name>encoding</param-name>             <param-value>UTF-8</param-value>         </init-param>         <init-param>             <param-name>forceEncoding</param-name>             <param-value>true</param-value>         </init-param>     </filter>     <filter-mapping>         <filter-name>characterEncoding</filter-name>         <url-pattern>/*</url-pattern>     </filter-mapping>
3	配置shiroFilter实例  <!--shiro的配置，关键两点，配置SecurityManager和依赖的RealM-->     <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">         <property name="securityManager" ref="securityManager" />         <property name="loginUrl" value="/admin/login" />         <property name="successUrl" value="/admin/home" />         <property name="unauthorizedUrl" value="/admin/login" />         <property name="filters">             <map>                 <entry key="anno" value-ref="anno"/>                 <entry key="authc" value-ref="authc"/>             </map>         </property>         <property name="filterChainDefinitionMap">             <map>                 <entry key="anon" value="anon"/>                 <entry key="authc" value="authc"/>             </map>         </property>         <property name="filterChainDefinitions">             <value>                 /admin/login=anon                 /admin/validCode=anon                 /user/**=authc                 /role/**=authc                 /permission/**=authc                 /**=authc             </value>         </property>     </bean>     <bean id="authc" class="com.util.filter.MyAccessFilter"/>     <bean id="anno" class="org.apache.shiro.web.filter.authc.AnonymousFilter"/>     <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">         <property name="realm" ref="myRealm"/>     </bean>     <bean id="myRealm" class="com.util.MysqlJdbcRealM"/>
4	开发跟shiro交互的RealM，一般把权限信息放到db中 package com.util; import com.domain.User; import com.domain.UserDto; import com.google.common.base.Strings; import com.service.UserDtoService; import com.service.UserService; import org.apache.shiro.authc.*; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.realm.jdbc.JdbcRealm; import org.apache.shiro.subject.PrincipalCollection; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import javax.annotation.Resource; /** * User： cutter.li * Date： 2014/6/19 0019 * Time： 15:24 * 备注： 自定义的mysql数据源 */ @Component public class MysqlJdbcRealM extends JdbcRealm     @Resource     private UserService userService;     //登录认证     @Override     protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException         UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;         String username = String.valueOf(usernamePasswordToken.getUsername());         User user = userService.findByUserName(username);         AuthenticationInfo authenticationInfo = null;         if (null != user)             String password = new String(usernamePasswordToken.getPassword());             if (password.equals(user.getPassword()))                 authenticationInfo = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName());                             return authenticationInfo;         //授权     @Override     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals)         String username = (String) principals.getPrimaryPrincipal();         if (!Strings.isNullOrEmpty(username))             SimpleAuthorizationInfo authenticationInfo = new SimpleAuthorizationInfo();             authenticationInfo.setRoles(userService.findRolesStr(username));             authenticationInfo.setStringPermissions(userService.findPermissionsStr(username));             return authenticationInfo;                 return null;
5	简单的登录页面，功能测试
6	controller的实现：  @RequestMapping(value = "login", method = RequestMethod.POST)     public ResponseEntity<Message> loginSubmit(String username, String password, String vcode, HttpServletRequest request)         message.setSuccess();         validateLogin(message, username, password, vcode);         try //            String code = request.getSession().getAttribute(AppConstant.KAPTCHA_SESSION_KEY).toString(); //            if (!vcode.equalsIgnoreCase(code)) //                message.setCode(AppConstant.VALIDCODE_ERROR); //                message.setMsg("验证码错误"); //                        if (message.isSuccess())                 Subject subject = SecurityUtils.getSubject();                 subject.login(new UsernamePasswordToken(username, password));                 if (subject.isAuthenticated())                         message.setMsg("登录成功");                 else                     message.setCode(AppConstant.USERNAME_NOTEXIST);                     message.setMsg("用户名/密码错误");                                     catch (AuthenticationException ex)             message.setCode(AppConstant.USERNAME_NOTEXIST);             message.setMsg("用户名/密码错误");             ex.printStackTrace();                 finally             return new ResponseEntity<Message>(message, HttpStatus.OK);
7	指定认证的策略和多数据源     <!--shiro的配置-->     <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">         <property name="securityManager" ref="securityManager" />         <property name="loginUrl" value="/admin/login" />         <property name="successUrl" value="/admin/home" />         <property name="unauthorizedUrl" value="/admin/login" />         <property name="filters">             <map>                 <entry key="anno" value-ref="anno"/>                 <entry key="authc" value-ref="authc"/>             </map>         </property>         <property name="filterChainDefinitionMap">             <map>                 <entry key="anon" value="anon"/>                 <entry key="authc" value="authc"/>             </map>         </property>         <property name="filterChainDefinitions">             <value>                 /admin/login=anon                 /admin/validCode=anon                 /user/**=authc                 /role/**=authc                 /permission/**=authc                 /**=authc             </value>         </property>     </bean>     <bean id="authc" class="com.util.filter.MyAccessFilter"/>     <bean id="anno" class="org.apache.shiro.web.filter.authc.AnonymousFilter"/>     <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">         <property name="authenticator" ref="modelAuthricator"/>     </bean>     <bean id="modelAuthricator" class="org.apache.shiro.authc.pam.ModularRealmAuthenticator">         <property name="authenticationStrategy" ref="firstSuccess"/>         <property name="realms">            <list>              <ref local="myRealm"/>            </list>         </property>     </bean>     <bean id="firstSuccess" class="org.apache.shiro.authc.pam.FirstSuccessfulStrategy"/>
