Sa-Token v1.37.0

一个轻量级 Java 权限认证框架,让鉴权变得简单、优雅!


前言:

  • 在线文档:https://sa-token.cc

  • 注:学习测试请拉取 master 分支,dev 是开发分支,有很多特性并不稳定(在项目根目录执行 git checkout master)。

  • 开源不易,点个 star 鼓励一下吧!

Sa-Token 介绍

Sa-Token 是一个轻量级 Java 权限认证框架,主要解决:登录认证、权限认证、单点登录、OAuth2.0、分布式Session会话、微服务网关鉴权 等一系列权限相关问题。

Sa-Token 旨在以简单、优雅的方式完成系统的权限认证部分,以登录认证为例,你只需要:

// 会话登录,参数填登录人的账号id 
StpUtil.login(10001);

无需实现任何接口,无需创建任何配置文件,只需要这一句静态代码的调用,便可以完成会话登录认证。

如果一个接口需要登录后才能访问,我们只需调用以下代码:

// 校验当前客户端是否已经登录,如果未登录则抛出 `NotLoginException` 异常
StpUtil.checkLogin();

在 Sa-Token 中,大多数功能都可以一行代码解决:

踢人下线:

// 将账号id为 10077 的会话踢下线 
StpUtil.kickout(10077);

权限认证:

// 注解鉴权:只有具备 `user:add` 权限的会话才可以进入方法
@SaCheckPermission("user:add")
public String insert(SysUser user) {
    // ... 
    return "用户增加";
}

路由拦截鉴权:

// 根据路由划分模块,不同模块不同鉴权 
registry.addInterceptor(new SaInterceptor(handler -> {
	SaRouter.match("/user/**", r -> StpUtil.checkPermission("user"));
	SaRouter.match("/admin/**", r -> StpUtil.checkPermission("admin"));
	SaRouter.match("/goods/**", r -> StpUtil.checkPermission("goods"));
	SaRouter.match("/orders/**", r -> StpUtil.checkPermission("orders"));
	SaRouter.match("/notice/**", r -> StpUtil.checkPermission("notice"));
	// 更多模块... 
})).addPathPatterns("/**");

当你受够 Shiro、SpringSecurity 等框架的三拜九叩之后,你就会明白,相对于这些传统老牌框架,Sa-Token 的 API 设计是多么的简单、优雅!

Sa-Token 功能模块一览

Sa-Token 目前主要五大功能模块:登录认证、权限认证、单点登录、OAuth2.0、微服务鉴权。

  • 登录认证 —— 单端登录、多端登录、同端互斥登录、七天内免登录
  • 权限认证 —— 权限认证、角色认证、会话二级认证
  • Session会话 —— 全端共享Session、单端独享Session、自定义Session
  • 踢人下线 —— 根据账号id踢人下线、根据Token值踢人下线
  • 账号封禁 —— 登录封禁、按照业务分类封禁、按照处罚阶梯封禁
  • 持久层扩展 —— 可集成Redis、Memcached等专业缓存中间件,重启数据不丢失
  • 分布式会话 —— 提供jwt集成、共享数据中心两种分布式会话方案
  • 微服务网关鉴权 —— 适配Gateway、ShenYu、Zuul等常见网关的路由拦截认证
  • 单点登录 —— 内置三种单点登录模式:无论是否跨域、是否共享Redis,都可以搞定
  • OAuth2.0认证 —— 轻松搭建 OAuth2.0 服务,支持openid模式
  • 二级认证 —— 在已登录的基础上再次认证,保证安全性
  • Basic认证 —— 一行代码接入 Http Basic 认证
  • 独立Redis —— 将权限缓存与业务缓存分离
  • 临时Token认证 —— 解决短时间的Token授权问题
  • 模拟他人账号 —— 实时操作任意用户状态数据
  • 临时身份切换 —— 将会话身份临时切换为其它账号
  • 前后台分离 —— APP、小程序等不支持Cookie的终端
  • 同端互斥登录 —— 像QQ一样手机电脑同时在线,但是两个手机上互斥登录
  • 多账号认证体系 —— 比如一个商城项目的user表和admin表分开鉴权
  • Token风格定制 —— 内置六种Token风格,还可:自定义Token生成策略、自定义Token前缀
  • 注解式鉴权 —— 优雅的将鉴权与业务代码分离
  • 路由拦截式鉴权 —— 根据路由拦截鉴权,可适配restful模式
  • 自动续签 —— 提供两种Token过期策略,灵活搭配使用,还可自动续签
  • 会话治理 —— 提供方便灵活的会话查询接口
  • 记住我模式 —— 适配[记住我]模式,重启浏览器免验证
  • 密码加密 —— 提供密码加密模块,可快速MD5、SHA1、SHA256、AES、RSA加密
  • 全局侦听器 —— 在用户登陆、注销、被踢下线等关键性操作时进行一些AOP操作
  • 开箱即用 —— 提供SpringMVC、WebFlux等常见web框架starter集成包,真正的开箱即用

Sa-Token-SSO 单点登录

Sa-Token-SSO 由简入难划分为三种模式,解决不同架构下的 SSO 接入问题:

系统架构 采用模式 简介 文档链接
前端同域 + 后端同 Redis 模式一 共享Cookie同步会话 文档示例
前端不同域 + 后端同 Redis 模式二 URL重定向传播会话 文档示例
前端不同域 + 后端 不同Redis 模式三 Http请求获取会话 文档示例
  1. 前端同域:就是指多个系统可以部署在同一个主域名之下,比如:c1.domain.comc2.domain.comc3.domain.com
  2. 后端同Redis:就是指多个系统可以连接同一个Redis。PS:这里并不需要把所有项目的数据都放在同一个Redis中,Sa-Token提供了 [权限缓存与业务缓存分离] 的解决方案,详情戳:Alone独立Redis插件
  3. 如果既无法做到前端同域,也无法做到后端同Redis,那么只能走模式三,Http请求获取会话(Sa-Token对SSO提供了完整的封装,你只需要按照示例从文档上复制几段代码便可以轻松集成)

Sa-Token-OAuth2 授权认证

Sa-OAuth2 模块分为四种授权模式,解决不同场景下的授权需求

授权模式 简介
授权码(Authorization Code) OAuth2.0 标准授权步骤,Server 端向 Client 端下放 Code 码,Client 端再用 Code 码换取授权 Token
隐藏式(Implicit) 无法使用授权码模式时的备用选择,Server 端使用 URL 重定向方式直接将 Token 下放到 Client 端页面
密码式(Password) Client直接拿着用户的账号密码换取授权 Token
客户端凭证(Client Credentials) Server 端针对 Client 级别的 Token,代表应用自身的资源授权
