shiro在SSM以及与Springboot+Mybatis中的实践

公司项目使用的是前后端分离的方式编写项目，并且我们后台项目打包是打包成jar，所以没有web.xml这个文件。公司是使用SpringBoot+Mybatis+Shiro的框架编写，使用Maven这个插件构建项目的。下面是我根据公司项目总结的如何使用java文件来配置Shiro环境的。参考文档如下：     SSM中shiro的实现：            http://blog.csdn.net/xiangwanpeng/article/details/54793768      多Realm的学习：               http://blog.csdn.net/u010837612/article/details/46053249  

1、在POM.xml中加入依赖

 1.1首先我们需要了解一下shiro常用jar包含义：           核心包shiro-core           Web相关包shiro-web           缓存包shiro-ehcache           与spring整合包shiro-spring           Ehcache缓存核心包ehcache-core           Shiro自身日志包slf4j-jdk141.2加入依赖

        <dependency>              <groupId>org.apache.shiro</groupId>              <artifactId>shiro-core</artifactId>              <version>1.4.0</version>          </dependency>         <!--这个里面就已经会有web这个jar包了-->       <dependency>           <groupId>org.apache.shiro</groupId>           <artifactId>shiro-spring</artifactId>           <version>1.4.0</version>       </dependency>       <dependency>           <groupId>org.apache.shiro</groupId>           <artifactId>shiro-ehcache</artifactId>           <version>1.4.0</version>       </dependency>

2、编写核心文件

首先我们需要了解一下Realm的含义：    shiro要进行身份验证，就要从realm中获取相应的身份信息来进行验证，简单来说，我们可以自行定义realm，    在realm中，从数据库获取身份信息，然后和 用户输入的身份信息进行匹配。这一切都由我们自己来定义。多Realm是由于多个不同的身份造成的2.1在有web.xml的情况下编写      2.1.1在web.xml中配置shiroFilter

    <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>

      2.1.2编写自己的身份认证以及搜权（这个是通过继承AuthorizingRealm实现的）        是通过doGetAuthorizationInfo授予权限和AuthenticationToken登录身份验证两个方法实现的

@Componentpublic class MemberAccountRealm extends AuthorizingRealm {    @Autowired    private MemberAccountService memberAccountService;    /**     * 授权(验证权限时调用)     */    @Override    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {        // 获取登录时输入的用户名          MemberAccount memberAccount = (MemberAccount) principals.getPrimaryPrincipal();        String account = memberAccount.getAccount();        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();        // 用户角色授权        addRole(account, info);        // 用户权限授权        addPermisson(account, info);        return info;    }    /**     * 用户身份认证(登录时调用)     */    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws RuntimeException{        UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken)token;        // 获取前台用户输入的用户名和密码        String telephone = (String) token.getPrincipal();        // 查询用户信息        MemberAccount memberAccount=null;        try {            memberAccount = this.memberAccountService.queryMemberAccount(telephone, IsDelete.IS_NOT_DELETE);        } catch (Exception e) {            e.printStackTrace();            throw new RuntimeException(e);        }        // 获取密码并加密        String password = ShiroUtils.passwordEncrypr(String.valueOf(usernamePasswordToken.getPassword()), String.valueOf(memberAccount.getMemberId()));        // 重新放到token中        usernamePasswordToken.setPassword(password.toCharArray());        // 若存在，将此用户存放到登录认证中进行密码匹配        return new SimpleAuthenticationInfo(memberAccount,memberAccount.getPassword(), ByteSource.Util.bytes(telephone),getName());    }    /**     *      * 模拟授予权限     * @param loginName     * @param info     */    private void addPermisson(String loginName, SimpleAuthorizationInfo info) {        List<String> permissonList = new ArrayList<String>();        permissonList.add("sys:user:delete");        permissonList.add("sys:user:update");        permissonList.add("sys:user:save");        permissonList.add("sys:user:list");        //用户角色列表        Set<String> permissonSet = new HashSet<String>();             for ( String perm : permissonList ) {            if (StringUtils.isBlank(perm)) {                continue;            }            permissonSet.addAll(Arrays.asList(perm.trim().split(",")));        }        info.setStringPermissions(permissonSet);    }    /**     *      * 用户角色授权     * @param loginName     * @param info     */    private void addRole(String loginName, SimpleAuthorizationInfo info) {        List<String> RoleList = new ArrayList<String>();        RoleList.add("admin");        //用户角色列表        Set<String> RoleSet = new HashSet<String>();        for ( String role : RoleList ) {            if (StringUtils.isBlank(role)) {                continue;            }            RoleSet.addAll(Arrays.asList(role.trim().split(",")));        }        info.setRoles(RoleSet);    }}

      2.1.3可以自定义一个密码验证方法

public class CredentialsMatcher extends SimpleCredentialsMatcher{    @Override    public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {        UsernamePasswordToken utoken = (UsernamePasswordToken) token;        // 获得用户输入的密码:(可以采用加盐(salt)的方式去检验)        String inPassword = new String(utoken.getPassword());        // 获得数据库中的密码        String dbPassword = (String) info.getCredentials();        // 进行密码的比对        return this.equals(inPassword, dbPassword);    }}

      2.1.4在src目录下家里ehcache.xml,文件内容如下：

      2.1.5在spring的配置文件中加入以下代码：

     <!-- shiro start -->    <!-- 1. 配置SecurityManager -->    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">        <property name="cacheManager" ref="cacheManager" />        <!--这个是配置的多Realm的-->        <!--<property name="authenticator" ref="authenticator"></property>-->        <!-- 可以配置多个Realm，其实会把realms属性赋值给ModularRealmAuthenticator的realms属性 -->        <property name="realms">            <list>                <ref bean="authRealm" />            </list>        </property>    </bean>    <!-- 2. 配置CacheManager -->    <!-- 2.1 需要加入ehcache的jar包及配置文件 -->    <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">        <property name="cacheManagerConfigFile" value="classpath:ehcache.xml" />    </bean>    <!-- 3. 配置Realm -->    <!-- 3.1 直接配置继承了org.apache.shiro.realm.AuthorizingRealm的bean -->    <bean id="authRealm" class="com.ysw.mes.common.shiro.MemberAccountRealm">        <!-- 配置密码匹配器 -->        <!-- 非自定义的写法        <property name="credentialsMatcher">            <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">                <!-- 加密算法为MD5 -->                <property name="hashAlgorithmName" value="MD5"></property>                <!-- 加密次数 -->                <property name="hashIterations" value="1024"></property>            </bean>        </property>         -->         <!-- 自定义的写法 -->         <property name="credentialsMatcher" ref="credentialsMatcher">    </bean>    <!-- 自定义的密码匹配器 -->    <bean id="credentialsMatcher" class="com.ysw.mes.common.shiro.CredentialsMatcher"/>    <!-- 4. 配置LifecycleBeanPostProcessor，可以自定义地来调用配置在Spring IOC容器中shiro bean的生命周期方法 -->    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />    <!-- 5. 使能够在IOC容器中使用shiro的注解，但必须在配置了LifecycleBeanPostProcessor之后才可以使用 -->    <bean        class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"        depends-on="lifecycleBeanPostProcessor" />    <bean        class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">        <property name="securityManager" ref="securityManager" />    </bean>    <!-- 6. 配置ShiroFilter -->    <!-- 6.1 id必须和web.xml中配置的DelegatingFilterProxy的<filter-name>一致。 如果不一致，会抛出NoSuchBeanDefinitionException异常，因为shiro会在IOC容器中查找名称和<filter-name>         值一致的filter bean -->    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">        <property name="securityManager" ref="securityManager" />        <property name="loginUrl" value="/login.jsp" />        <!--<property name="successUrl" value="/home" />-->        <!-- 配置哪些页面需要受保护，以及访问这些页面需要的权限        <property name="filterChainDefinitions">            <value>                <!-- 第一次匹配优先的原则 -->                /jsp/login.jsp* = anon                /loginUser = anon                /logout* = anon                /jsp/error.jsp* = anon                /jsp/index.jsp* = authc                /* = authc                /*.* = authc            </value>        </property>         -->    </bean>    <!-- 7. 配置ModularRealmAuthenticator，可以实现多Realm认证 （公司项目并没有使用到）    <bean id="authenticator" class="org.apache.shiro.authc.pam.ModularRealmAuthenticator">        <!-- 配置认证策略，只要有一个Realm认证成功即可，并且返回所有认证成功信息 -->        <property name="authenticationStrategy">            <bean class="org.apache.shiro.authc.pam.AtLeastOneSuccessfulStrategy"></bean>        </property>    </bean>    -->    <!-- shiro end -->

2.2在无web.xml的情况下编写(在这里我就不配置cache了，相信大家会写的哈)    2.2.1编写同上的2.1.2、2.1.3    2.2.2编写一个Shiro的配置文件如下（相当于上面的 2.1.1和2.1.5的作用）

import java.util.LinkedHashMap;import org.apache.shiro.mgt.SecurityManager;import org.apache.shiro.spring.LifecycleBeanPostProcessor;import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;import org.apache.shiro.spring.web.ShiroFilterFactoryBean;import org.apache.shiro.web.mgt.DefaultWebSecurityManager;import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import com.ysw.mes.common.shiro.CredentialsMatcher;import com.ysw.mes.common.shiro.MemberAccountRealm;/** * 这个是shiro的配置文件 * 这个文件会使用到 *  CredentialsMatcher和MemberAccountRealm这两个文件 * @author admin *  *  * 学习shiro的网址有： *      http://blog.csdn.net/xiangwanpeng/article/details/54793768 *  *      其中对于多Realm的解释： *  * */@Configurationpublic class ShiroConfiguration {    /**     *      * @param manager     * @return     */    @Bean(name="shiroFilter")    public ShiroFilterFactoryBean shiroFilter(@Qualifier("securityManager") SecurityManager manager) {        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();        bean.setSecurityManager(manager);        // 配置登录的url和登录成功的url        bean.setLoginUrl("/toLogin");//      bean.setSuccessUrl("/home");        // 配置访问权限        LinkedHashMap<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();//        filterChainDefinitionMap.put("/jsp/login.jsp*", "anon"); //表示可以匿名访问//        filterChainDefinitionMap.put("/loginUser", "anon"); //        filterChainDefinitionMap.put("/logout*","anon");//        filterChainDefinitionMap.put("/jsp/error.jsp*","anon");//        filterChainDefinitionMap.put("/jsp/index.jsp*","authc");//        filterChainDefinitionMap.put("/*", "authc");//表示需要认证才可以访问//        filterChainDefinitionMap.put("/**", "authc");//表示需要认证才可以访问//        filterChainDefinitionMap.put("/*.*", "authc");        bean.setFilterChainDefinitionMap(filterChainDefinitionMap);        return bean;    }    //配置核心安全事务管理器    @Bean(name="securityManager")    public SecurityManager securityManager(@Qualifier("authRealm") MemberAccountRealm authRealm) {        System.err.println("--------------shiro已经加载----------------");        DefaultWebSecurityManager manager = new DefaultWebSecurityManager();        manager.setRealm(authRealm);        return manager;    }    @    /**     * 配置自定义的权限以及身份认证器     * 以及将自定义的密码比较器注入进去     * @param matcher     * @return     */    @Bean(name="authRealm")    public MemberAccountRealm authRealm(@Qualifier("credentialsMatcher") CredentialsMatcher matcher) {        MemberAccountRealm authRealm=new MemberAccountRealm();        authRealm.setCredentialsMatcher(matcher);        return authRealm;    }    /**     * 使用的是自定义的密码比较器CredentialsMatcher     *      * @return CredentialsMatcher是自定义类     */    @Bean(name="credentialsMatcher")    public CredentialsMatcher credentialsMatcher() {        return new CredentialsMatcher();    }    /**     * 配置LifecycleBeanPostProcessor，可以自定义地来调用配置在Spring IOC容器中shiro bean的生命周期方法     * @return     */    @Bean    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor(){        return new LifecycleBeanPostProcessor();    }    /**     * 使能够在IOC容器中使用shiro的注解，但必须在配置了LifecycleBeanPostProcessor之后才可以使用     * @return     */    @Bean    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator(){        DefaultAdvisorAutoProxyCreator creator=new DefaultAdvisorAutoProxyCreator();        creator.setProxyTargetClass(true);        return creator;    }    @Bean    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") SecurityManager manager) {        AuthorizationAttributeSourceAdvisor advisor=new AuthorizationAttributeSourceAdvisor();        advisor.setSecurityManager(manager);        return advisor;    }}

在写完上面内容后，再看一次系统后，发现登录验证的顺序原来是这样的
1、由于在shiro的配置文件中配置了


2、首先访问/toLogin这个对应的方法

3、由于subject.login(token)这个，会调用到

4、将数据塞进token和info这两个实体之后进行比较
