在学习shiro之后，体会到了shiro的功能强大以及使用方便，初步总结一下shiro和spring 整合，以及用户登录身份的验证。

项目是基于maven搭建的，首先贴上部分整合需要的pom文件，因为是从项目中截取的，所以spring的配置比较完善

    <!-- 添加Spring支持 -->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-core</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-beans</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-tx</artifactId>         <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context-support</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-web</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-webmvc</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-aop</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-aspects</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-jdbc</artifactId>        <version>4.2.9.RELEASE</version>    </dependency>    <!-- 添加shiro支持 -->    <dependency>        <groupId>org.apache.shiro</groupId>        <artifactId>shiro-core</artifactId>        <version>1.2.4</version>    </dependency>    <dependency>        <groupId>org.apache.shiro</groupId>        <artifactId>shiro-web</artifactId>        <version>1.2.4</version>    </dependency>    <dependency>        <groupId>org.apache.shiro</groupId>        <artifactId>shiro-spring</artifactId>        <version>1.2.4</version>    </dependency>

web.xml中 shiro过滤器的相关配置

    <!-- shiro过滤器定义 -->    <filter>        <filter-name>shiroFilter</filter-name>        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>        <init-param>            <!--该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理-->            <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>

接下来贴上spring-shiro的基本配置文件

<?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"    xmlns:mvc="http://www.springframework.org/schema/mvc"    xsi:schemaLocation="        http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-4.2.xsd                http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-4.2.xsd        http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-4.2.xsd        http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-4.2.xsd        http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">    <!-- 继承自AuthorizingRealm的自定义Realm,即指定Shiro验证用户登录的类为自定义的BloggerRealm.java -->    <bean id="bloggerRealm" class="cn.xustars.myblog.shiro.BloggerRealm"/>    <!-- Shiro默认会使用Servlet容器的Session,可通过sessionMode属性来指定使用Shiro原生Session -->      <!-- 即<property name="sessionMode" value="native"/>,详细说明见官方文档 -->      <!-- 这里主要是设置自定义的单Realm应用,若有多个Realm,可使用'realms'属性代替 -->      <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">          <property name="realm" ref="bloggerRealm"/>    </bean>    <!-- Shiro主过滤器本身功能十分强大,其强大之处就在于它支持任何基于URL路径表达式的、自定义的过滤器的执行 -->      <!-- Web应用中,Shiro可控制的Web请求必须经过Shiro主过滤器的拦截,Shiro对基于Spring的Web应用提供了完美的支持 -->      <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">          <!-- Shiro的核心安全接口,这个属性是必须的 -->          <property name="securityManager" ref="securityManager"/>          <!-- 要求登录时的链接(可根据项目的URL进行替换),非必须的属性,默认会自动寻找Web工程根目录下的"/login.html"页面 -->          <property name="loginUrl" value="/login.html"/>        <!-- 登录成功后要跳转的连接 -->          <property name="successUrl" value="/index.html"/>        <!-- 用户访问未对其授权的资源时,所显示的连接 -->          <!-- 若想更明显的测试此属性可以修改它的值,如unauthor.jsp,然后匿名登录后访问/admin/listUser.jsp就看见浏览器会显示unauthor.jsp -->        <property name="unauthorizedUrl" value="/"/>          <!-- Shiro连接约束配置,即过滤链的定义 -->          <!-- 此处可配合我的这篇文章来理解各个过滤连的作用http://blog.csdn.net/jadyer/article/details/12172839 -->          <!-- 下面value值的第一个'/'代表的路径是相对于HttpServletRequest.getContextPath()的值来的 -->          <!-- anon：它对应的过滤器里面是空的,什么都没做,这里.do和.jsp后面的*表示参数,比方说login.jsp?main这种 -->          <!-- authc：该过滤器下的页面必须验证后才能访问,它是Shiro内置的一个拦截器org.apache.shiro.web.filter.authc.FormAuthenticationFilter -->          <property name="filterChainDefinitions">              <value>                /statics/**=anon                /resources/**=anon                /js/common.js*=anon                /login.html=anon                /blogger/login=anon                /**=authc            </value>        </property>    </bean>    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>    <!-- AOP式方法级权限检查  -->    <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></beans>

因为这篇博客我们主要讲用户身份认证这一块，至于shiro的用户权限分配认证，下一篇博客会给大家介绍，下面是用户验证的核心代码。

/**     * 用户认证     */    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {        String username = (String) token.getPrincipal();        String password = new String ((char[]) token.getCredentials());        BloggerInfo bloggerInfo = bloggerService.queryByUserName(username);        //账号不存在        if(bloggerInfo == null) {            throw new UnknownAccountException("账号或密码不正确");        }        //密码错误        if(!password.equals(bloggerInfo.getPassword())) {            throw new IncorrectCredentialsException("账号或密码不正确");        }        SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(username,password,getName());        return simpleAuthenticationInfo;    }

controller中登录验证的方法

     /**     * 登录     * RetObj 用来返回状态消息的工具类     */    @RequestMapping(value = "/blogger/login",method = RequestMethod.POST)    @ResponseBody    public RetObj login(String username,String password) {        try {            //获取当前的subject对象            Subject subject = SecurityUtils.getSubject();            UsernamePasswordToken token = new UsernamePasswordToken(username, password);            subject.login(token);        }catch (AuthenticationException e){            return RetObj.error("用户验证失败");        }        return RetObj.ok();    }
