什么是ACL和RBAC

ACL

Access Control list：访问控制列表
优点：简单易用，开发便捷
缺点：用户和权限直接挂钩，导致在授予时的复杂性，比较分散，不便于管理
例子：常见的文件系统权限设计，直接给用户加权限

RBAC

Role Based Access Control：基于角色的访问控制
权限与角色相关联，用户通过成为适当角色的成员而得到这些角色的权限
优点：简化了用户与权限的管理，通过对用户进行分类，使得角色与权限关联起来
缺点：开发比ACL相对复杂
例子：基于RBAC模型的权限验证框架，Apache Shiro

什么是Apache Shiro

官网地址

点我直达

介绍

　　Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。

什么是身份认证

　　Authentication，身份认证，一般就是登陆校验

什么是授权

　　Authorization，给用户分配角色或者访问某些资源的权限

什么是会话管理

　　Session Management，用户的会话管理员，多数情况下是web session

什么是加密

　　Cryptography，数据加密，比如密码加解密

核心概念

Subject

　　我们把用户或者程序称为主体，主体去访问系统或者资源

SecurityManager

　　安全管理器，Subject的认证和授权都要在安全管理器下进行

Realm

　　数据域，Shiro和安全数据的连接器，通过realm获取认证授权相关信息

Authenticator

　　认证器，主要负责Subject的认证

Authorizer

　　授权器，主要负责Subject的授权，控制Subject拥有的角色或者权限

Crytography

　　加解密，Shiro的包含易于使用和理解的数据加解密方法，简化了很多复杂的API

Cache Manager

　　缓存管理器，比如认证或授权信息，通过缓存进行管理，提高性能

realm实战

作用

　　Shiro从Realm获取安全数据

概念

principal：主体的标识，可以有多个，但是需要具有唯一性，如：手机号、邮箱
credential：凭证，一般就是密码

建表语句.sql

注意

　　表名和字段要对应上，否则自定义定，继承：AuthorizingRealm，重写sql查询语句！！！！并重新指定realm类型！！！！

QuickStartJdbc2Test.java

自定义realm

　　继承AuthorizingRealm，重写授权方法doGetAuthorizationInfo、重写认证方法doGetAuthenticationInfo。

　　UsernamePasswordToken：对应就是shiro的token中有Principal和Credential。

　　SimpleAuthorizationInfo：代表用户角色权限信息

　　SimpleAuthenticationInfo：代表该用户的认证信息

Filter过滤器

核心过滤器
- DefaultFilter，配置那个路径对应那个拦截器进行处理
authc：org.apache.shiro.web.filter.authc.FormAuthenticationFilter
- 需要认证登录才能访问
user：org.apache.shiro.web.filter.authc.UseerrFilter
- 用户拦截器，表示必须存在用户
anon：org.apache.shiro.web.filter.authc.AnonymoousFilter
- 匿名拦截器，不需要登录即可访问的资源，匿名用户或游客，一般用于过滤静态资源。
roles：org.apache.shiro.web.filter.authz.RolesAuthorizationFilter
- 角色授权拦截器，验证用户是否拥有角色
- 参数可写多个，表示某些角色才能通过，多个参数时，写roles["root,role1"]，当有多个参数时必须每个参数都通过才算通过
perms：org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter
- 权限授权拦截器，验证用户是否拥有权限
- 参数可写多个，表示需要某些权限才能通过，多个参数写perms["user,admin"]，当有多个参数时必须每个参数都通过才算可以
authcBasci：org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter
- httpBasic，身份验证拦截器
logout：org.apache.shiro.web.filter.authc.LogoutFilter
- 退出拦截器，执行后会直接跳转到shiroFilterFactoryBean.setLoginUrl()，设置的url
port：org.apache.shiro.web.filter.authz.PortFilter
- 端口拦截器，可通过的端口
ssl：org.apache.shiro.web.filter.authz.SslFilter
- ssl拦截器，只有请求协议是https才能通过

Filter配置路径

路径通配符支持?、*、**，注意通配符匹配不包含目录分隔符“/”
*：可以匹配所有，不加*，可以进行前缀匹配，但多个冒号就需要多个*来匹配

url权限采取第一次匹配优先的方式?：匹配一个字符，如：/user?，匹配：/user1，但不匹配：/user/*：匹配零个或多个字符串，如：/add*，匹配：/addtest，但不匹配：/user/1**：匹配路径中的零个或多个路径，如：/user/**将匹配：/user/xxx/yyy

Shiro权限控制注解

注解方式

@RequiresRoles(value={"admin","editor"},logical=Logical.AND)
- 需要角色：admin和editor两个角色，AND表示两个同时成立
RequiresPermissions(value={"user:add","user:del"},logical.OR)
- 需要权限user:add或user:del权限其中一个，OR是或的意思
@RequiresAuthentication
- 已经授过权，调用Subject.isAuthenticated()返回true
@RequiresUser
- 身份验证或通过记住我登录过的

使用文件的方式

　　使用ShiroConfig。

Filter过滤器

业务需求

一个接口，可以让2个角色中的任意一个访问
自定义一个类，继承：AuthorizationFilter

package com.ybchen.springboot_shiro.config;import org.apache.shiro.subject.Subject;import org.apache.shiro.util.CollectionUtils;import org.apache.shiro.web.filter.authz.AuthorizationFilter;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import java.util.Set;/** * @Description：自定义Filter * @Author：chenyanbin * @Date：2021/1/4 11:14 下午 * @Versiion：1.0 */public class CustomRolesOrAuthorizationFilter extends AuthorizationFilter {    @Override    protected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {        Subject subject = getSubject(request, response);        //filterChainDefinitionMap.put("/admin/**", "roles[admin,user]"); mappedValue <==> admin,user        String[] rolesArray = (String[]) mappedValue;        if (rolesArray == null || rolesArray.length == 0) {            return true;        }        Set<String> roles = CollectionUtils.asSet(rolesArray);        //当前subject是roles中的任意一个，则有权限访问        for (String role : roles) {            if (subject.hasRole(role)) {                return true;            }        }        return false;    }}

@Bean    public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) {        System.out.println("ShiroConfig ShiroFilterFactoryBean 执行");        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();        //设置SecurityManager        shiroFilterFactoryBean.setSecurityManager(securityManager);        //如果访问需要登录的某个接口，却没有登录，则调用此接口(如果不是前后端分离，则跳转页面)        shiroFilterFactoryBean.setLoginUrl("/pub/need_login");        //shiroFilterFactoryBean.setLoginUrl("/xxx.jsp");        //登录成功后，跳转的链接，若前后端分离，没必要设置这个        //shiroFilterFactoryBean.setSuccessUrl("");        //登录成功，未授权会调用此方法        shiroFilterFactoryBean.setUnauthorizedUrl("/pub/not_permit");        //设置自定义Filter        Map<String, Filter> filterMap=new LinkedHashMap<>();        filterMap.put("roleOrFilter",new CustomRolesOrAuthorizationFilter());        shiroFilterFactoryBean.setFilters(filterMap);        //拦截路径，必须使用:LinkedHashMap，要不然拦截效果会时有时无，因为使用的是无序的Map        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();        //key=正则表达式路径，value=org.apache.shiro.web.filter.mgt.DefaultFilter        //退出过滤器        filterChainDefinitionMap.put("/logout", "logout");        //匿名可以访问，游客模式        filterChainDefinitionMap.put("/pub/**", "anon");        //登录用户才可以访问        filterChainDefinitionMap.put("/authc/**", "authc");        //管理员角色才能访问//        filterChainDefinitionMap.put("/admin/**", "roles[admin,user]");        filterChainDefinitionMap.put("/admin/**", "roleOrFilter[admin,user]");        //有编辑权限才能访问        filterChainDefinitionMap.put("/video/update", "perms[video_update]");        //authc：url必须通过认证才可以访问        //anon：url可以匿名访问        //过滤链是顺序执行，从上而下，一般把/**，放到最下面        filterChainDefinitionMap.put("/**", "authc");        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);        return shiroFilterFactoryBean;    }

Redis整合CacheManager

原因

　　授权的时候每次都去查询数据库，对于频繁访问的接口，性能和响应速度比较慢，此处可以使用缓存，提高响应速度，也可以使用Guava(本地内存缓存)。

　　Redis(分布式缓存)还不了解的小伙伴，在这里我就不一一讲解了，可以看我以前写过的博客。

添加依赖

<!--shiro+redis-->        <dependency>            <groupId>org.crazycake</groupId>            <artifactId>shiro-redis</artifactId>            <version>3.3.1</version>        </dependency>

在ShiroConfig中添加如下代码

//使用自定义cacheManager    securityManager.setCacheManager(cacheManager());    /**     * 配置redisManager     * @return     */    public RedisManager getRedisManager(){        RedisManager redisManager=new RedisManager();        redisManager.setHost("127.0.0.1:6379");        //连接那个数据库        redisManager.setDatabase(0);        //设置密码//        redisManager.setPassword("123");        return redisManager;    }    /**     * 设置具体cache实现类     * @return     */    public RedisCacheManager cacheManager(){        RedisCacheManager redisCacheManager=new RedisCacheManager();        redisCacheManager.setRedisManager(getRedisManager());        return redisCacheManager;    }

修改CustomRealm

设置redis缓存过期时间

Redis整合SessionManager

为啥Session也要持久化

　　重启应用，用户无感知，可以继续以原先的状态继续访问。

修改shiroconfig
