shiro的使用1 简单的认证

最近在重构，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

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*/@Componentpublic 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”/>    <bean id=”myRealm” class=”com.util.MysqlJdbcRealM”/>
