SpringBoot整合Shiro实现动态权限加载更新+Sess

一. 说明

Shiro是一个安全框架,项目中主要用它做认证,授权,加密,以及用户的会话管理,虽然Shiro没有SpringSecurity功能更丰富,但是它轻量,简单,在项目中通常业务需求Shiro也都能胜任.

二. 项目环境

• MyBatis-Plus版本: 3.1.0

• SpringBoot版本:2.1.5

• JDK版本:1.8

• Shiro版本:1.4

• Shiro-redis插件版本:3.1.0

数据表(SQL文件在项目中):数据库中测试号的密码进行了加密,密码皆为123456

三. 编写项目基础类

用户实体,Dao,Service等在这里省略,请参考源码

编写Exception类来处理Shiro权限拦截异常

/**
 * @Description 自定义异常
 * @Author Sans
 * @CreateTime 2019/6/15 22:56
 */
@ControllerAdvice
public class MyShiroException {
    /**
     * 处理Shiro权限拦截异常
     * 如果返回JSON数据格式请加上 @ResponseBody注解
     * @Author Sans
     * @CreateTime 2019/6/15 13:35
     * @Return Map<Object> 返回结果集
     */
    @ResponseBody
    @ExceptionHandler(value = AuthorizationException.class)
    public Map<String,Object> defaultErrorHandler(){
        Map<String,Object> map = new HashMap<>();
        map.put("403","权限不足");
        return map;
    }
}

创建SHA256Util加密工具

/**
 * @Description Sha-256加密工具
 * @Author Sans
 * @CreateTime 2019/6/12 9:27
 */
public class SHA256Util {
    /**  私有构造器 **/
    private SHA256Util(){};
    /**  加密算法 **/
    public final static String HASH_ALGORITHM_NAME = "SHA-256";
    /**  循环次数 **/
    public final static int HASH_ITERATIONS = 15;
    /**  执行加密-采用SHA256和盐值加密 **/
    public static String sha256(String password, String salt) {
        return new SimpleHash(HASH_ALGORITHM_NAME, password, salt, HASH_ITERATIONS).toString();
    }
}

创建Spring工具

/**
 * @Description Spring上下文工具类
 * @Author Sans
 * @CreateTime 2019/6/17 13:40
 */
@Component
public class SpringUtil implements ApplicationContextAware {
    private static ApplicationContext context;
    /**
     * Spring在bean初始化后会判断是不是ApplicationContextAware的子类
     * 如果该类是,setApplicationContext()方法,会将容器中ApplicationContext作为参数传入进去
     * @Author Sans
     * @CreateTime 2019/6/17 16:58
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        context = applicationContext;
    }
    /**
     * 通过Name返回指定的Bean
     * @Author Sans
     * @CreateTime 2019/6/17 16:03
     */
    public static <T> T getBean(Class<T> beanClass) {
        return context.getBean(beanClass);
    }
}

创建Shiro工具

/**
 * @Description Shiro工具类
 * @Author Sans
 * @CreateTime 2019/6/15 16:11
 */
public class ShiroUtils {

    /** 私有构造器 **/
    private ShiroUtils(){}

    private static RedisSessionDAO redisSessionDAO = SpringUtil.getBean(RedisSessionDAO.class);

    /**
     * 获取当前用户Session
     * @Author Sans
     * @CreateTime 2019/6/17 17:03
     * @Return SysUserEntity 用户信息
     */
    public static Session getSession() {
        return SecurityUtils.getSubject().getSession();
    }

    /**
     * 用户登出
     * @Author Sans
     * @CreateTime 2019/6/17 17:23
     */
    public static void logout() {
        SecurityUtils.getSubject().logout();
    }

    /**
    * 获取当前用户信息
    * @Author Sans
    * @CreateTime 2019/6/17 17:03
    * @Return SysUserEntity 用户信息
    */
    public static SysUserEntity getUserInfo() {
      return (SysUserEntity) SecurityUtils.getSubject().getPrincipal();
    }

    /**
     * 删除用户缓存信息
     * @Author Sans
     * @CreateTime 2019/6/17 13:57
     * @Param  username  用户名称
     * @Param  isRemoveSession 是否删除Session
     * @Return void
     */
    public static void deleteCache(String username, boolean isRemoveSession){
        //从缓存中获取Session
        Session session = null;
        Collection<Session> sessions = redisSessionDAO.getActiveSessions();
        SysUserEntity sysUserEntity;
        Object attribute = null;
        for(Session sessionInfo : sessions){
            //遍历Session,找到该用户名称对应的Session
            attribute = sessionInfo.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);
            if (attribute == null) {
                continue;
            }
            sysUserEntity = (SysUserEntity) ((SimplePrincipalCollection) attribute).getPrimaryPrincipal();
            if (sysUserEntity == null) {
                continue;
            }
            if (Objects.equals(sysUserEntity.getUsername(), username)) {
                session=sessionInfo;
            }
        }
        if (session == null||attribute == null) {
            return;
        }
        //删除session
        if (isRemoveSession) {
            redisSessionDAO.delete(session);
        }
        //删除Cache，在访问受限接口时会重新授权
        DefaultWebSecurityManager securityManager = (DefaultWebSecurityManager) SecurityUtils.getSecurityManager();
        Authenticator authc = securityManager.getAuthenticator();
        ((LogoutAware) authc).onLogout((SimplePrincipalCollection) attribute);
    }
}

创建Shiro的SessionId生成器

/**
 * @Description 自定义SessionId生成器
 * @Author Sans
 * @CreateTime 2019/6/11 11:48
 */
public class ShiroSessionIdGenerator implements SessionIdGenerator {
    /**
     * 实现SessionId生成
     * @Author Sans
     * @CreateTime 2019/6/11 11:54
     */
    @Override
    public Serializable generateId(Session session) {
        Serializable sessionId = new JavaUuidSessionIdGenerator().generateId(session);
        return String.format("login_token_%s", sessionId);
    }
}

四. 编写Shiro核心类

创建Realm用于授权和认证

/**
 * @Description Shiro权限匹配和账号密码匹配
 * @Author Sans
 * @CreateTime 2019/6/15 11:27
 */
public class ShiroRealm extends AuthorizingRealm {
    @Autowired
    private SysUserService sysUserService;
    @Autowired
    private SysRoleService sysRoleService;
    @Autowired
    private SysMenuService sysMenuService;
    /**
     * 授权权限
     * 用户进行权限验证时候Shiro会去缓存中找,如果查不到数据,会执行这个方法去查权限,并放入缓存中
     * @Author Sans
     * @CreateTime 2019/6/12 11:44
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        SysUserEntity sysUserEntity = (SysUserEntity) principalCollection.getPrimaryPrincipal();
        //获取用户ID
        Long userId =sysUserEntity.getUserId();
        //这里可以进行授权和处理
        Set<String> rolesSet = new HashSet<>();
        Set<String> permsSet = new HashSet<>();
        //查询角色和权限(这里根据业务自行查询)
        List<SysRoleEntity> sysRoleEntityList = sysRoleService.selectSysRoleByUserId(userId);
        for (SysRoleEntity sysRoleEntity:sysRoleEntityList) {
            rolesSet.add(sysRoleEntity.getRoleName());

            for (SysMenuEntity sysMenuEntity :sysMenuEntityList) {
                permsSet.add(sysMenuEntity.getPerms());
            }
        }
        //将查到的权限和角色分别传入authorizationInfo中
        authorizationInfo.setStringPermissions(permsSet);
        authorizationInfo.setRoles(rolesSet);
        return authorizationInfo;
    }
    
    /**
     * 身份认证
     * @Author Sans

     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        //获取用户的输入的账号.
        String username = (String) authenticationToken.getPrincipal();
        //通过username从数据库中查找 User对象，如果找到进行验证
        //实际项目中,这里可以根据实际情况做缓存,如果不做,Shiro自己也是有时间间隔机制,2分钟内不会重复执行该方法
        SysUserEntity user = sysUserService.selectUserByName(username);
        //判断账号是否存在
        if (user == null) {
            throw new AuthenticationException();
        }
        //判断账号是否被冻结
        if (user.getState()==null||user.getState().equals("PROHIBIT")){
            throw new LockedAccountException();
        }
        //进行验证
        SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
                user,                                  //用户名
                user.getPassword(),                    //密码
                ByteSource.Util.bytes(user.getSalt()), //设置盐值
                getName()
        );
        //验证成功开始踢人(清除缓存和Session)
        ShiroUtils.deleteCache(username,true);
        return authenticationInfo;
    }
}

创建SessionManager类

/**
 * @Description 自定义获取Token

 */
public class ShiroSessionManager extends DefaultWebSessionManager {
    //定义常量
    private static final String AUTHORIZATION = "Authorization";

    //重写构造器
    public ShiroSessionManager() {

    }
    /**

    @Override
    public Serializable getSessionId(ServletRequest request, ServletResponse response) {
        String token = WebUtils.toHttp(request).getHeader(AUTHORIZATION);
        //如果请求头中存在token 则从请求头中获取token
        if (!StringUtils.isEmpty(token)) {
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, REFERENCED_SESSION_ID_SOURCE);

            return token;
        } else {
            //否则按默认规则从cookie取token
            return super.getSessionId(request, response);
        }
    }
}

五. 实现权限控制

Shiro可以用代码或者注解来控制权限,通常我们使用注解控制,不仅简单方便,而且更加灵活.Shiro注解一共有五个:

image

一般情况下我们在项目中做权限控制,使用最多的是RequiresPermissions和RequiresRoles,允许存在多个角色和权限,默认逻辑是AND,也就是同时拥有这些才可以访问方法,可以在注解中以参数的形式设置成OR

示例：

//拥有一个角色就可以访问
@RequiresRoles(value={"ADMIN","USER"},logical = Logical.OR)
//拥有所有权限才可以访问
@RequiresPermissions(value={"sys:user:info","sys:role:info"},logical = Logical.AND)

使用顺序:Shiro注解是存在顺序的,当多个注解在一个方法上的时候,会逐个检查,知道全部通过为止,默认拦截顺序是:RequiresRoles->RequiresPermissions->RequiresAuthentication->
RequiresUser->RequiresGuest

示例：

//拥有ADMIN角色同时还要有sys:role:info权限
@RequiresRoles(value={"ADMIN")
@RequiresPermissions("sys:role:info")

    }
}

六. POSTMAN测试

登录成功后会返回TOKEN,因为是单点登录,再次登陆的话会返回新的TOKEN,之前Redis的TOKEN就会失效了

image

当第一次访问接口后我们可以看到缓存中已经有权限数据了,在次访问接口的时候,Shiro会直接去缓存中拿取权限,注意访问接口时候要设置请求头.

image image

ADMIN这个号现在没有sys:info:all这个权限的,所以无法访问getInfoAll接口,我们要动态分配权限后,要清掉缓存,在访问接口时候,Shiro会去重新执行授权方法,之后再次把权限和角色数据放入缓存中

image

访问添加权限测试接口,因为是测试,我把增加权限的用户ADMIN写死在里面了,权限添加后,调用工具类清掉缓存,我们可以发现,Redis中已经没有缓存了

image image

再次访问getInfoAll接口,因为缓存中没有数据,Shiro会重新授权查询权限,拦截通过
