sa-token v1.12.1

这可能是史上功能最全的Java权限认证框架!


在线资料

Sa-Token是什么?

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、Session会话 等一系列权限相关问题

在架构设计上,sa-token拒绝引入复杂的概念,以实际业务需求为第一目标,业务上需要什么,sa-token就做什么,例如踢人下线、自动续签、同端互斥登录等常见业务在框架内均可以一行代码调用实现,简单粗暴,拒绝复杂!

对于传统Session会话模型的N多难题,例如难以分布式、水平扩展性差,难以兼容前后台分离环境,多会话管理混乱等, sa-token独创了以账号为主的User-Session模式,同时又兼容传统以token为主的Token-Session模式,两者彼此独立,互不干扰, 让你在进行会话管理时如鱼得水,在sa-toekn的强力加持下,权限问题将不再成为业务逻辑的瓶颈!

总的来说,与其它权限认证框架相比,sa-token具有以下优势:

  1. 上手简单:可零配置启动框架,能自动化的均已自动化,不让你费脑子
  2. 功能强大:能集成的功能全部集成,不让你用个框架还要自己给框架打各种补丁
  3. API简单易用:同样的一个功能,可能在别的框架中需要上百行代码,但是在sa-token中统统一行代码调个方法即可解决
  4. 组件易于扩展:框架中几乎所有组件都提供了对应的扩展接口,90%以上的逻辑都是可以被按需重写的

有了sa-token,你所有的权限认证问题,都不再是问题!

代码示例

sa-token的API调用非常简单,有多简单呢?以登录验证为例,你只需要:

// 在登录时写入当前会话的账号id 
StpUtil.setLoginId(10001);	

// 然后在任意需要校验登录处调用以下API  
// 如果当前会话未登录,这句代码会抛出 `NotLoginException`异常
StpUtil.checkLogin();	

至此,我们已经借助sa-token框架完成登录授权!

此时的你小脑袋可能飘满了问号,就这么简单?自定义Realm呢?全局过滤器呢?我不用写各种配置文件吗?

事实上在此我可以负责的告诉你,在sa-token中,登录授权就是如此的简单,不需要什么全局过滤器,不需要各种乱七八糟的配置!只需要这一行简单的API调用,即可完成会话的登录授权!

当你受够Shiro、Security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设计是多么的清爽!

权限认证示例 (只有具有user:add权限的会话才可以进入请求)

@SaCheckPermission("user:add")        
@RequestMapping("/user/insert")
public String insert(SysUser user) {
	return "用户增加";
}

将某个账号踢下线 (待到对方再次访问系统时会抛出NotLoginException异常)

// 使账号id为10001的会话注销登录
StpUtil.logoutByLoginId(10001); 

除了以上的功能,sa-token还可以一行代码完成以下功能:

StpUtil.setLoginId(10001);          // 标记当前会话登录的账号id
StpUtil.getLoginId();               // 获取当前会话登录的账号id
StpUtil.isLogin();                  // 获取当前会话是否已经登录, 返回true或false
StpUtil.logout();                   // 当前会话注销登录
StpUtil.logoutByLoginId(10001);     // 让账号为10001的会话注销登录(踢人下线)
StpUtil.hasRole("super-admin");     // 查询当前账号是否含有指定角色标识, 返回true或false
StpUtil.hasPermission("user:add");  // 查询当前账号是否含有指定权限, 返回true或false
StpUtil.getSession();               // 获取当前账号id的Session 
StpUtil.getSessionByLoginId(10001); // 获取账号id为10001的Session
StpUtil.getTokenValueByLoginId(10001);  // 获取账号id为10001的token令牌值
StpUtil.setLoginId(10001, "PC");        // 指定设备标识登录
StpUtil.logoutByLoginId(10001, "PC");   // 指定设备标识进行强制注销 (不同端不受影响)
StpUtil.switchTo(10044);                // 将当前会话身份临时切换为其它账号

迭代模式

sa-token的功能提案主要来源于社区,这意味着人人都可以参与到sa-token的功能定制,决定框架的未来走向, 如果你有好的想法,可以在issues提出或者加入群一起交流,对于社区的提出的功能要求,主要分为以下几类:

  • 对框架新增特性功能且比较简单,会在第一时间进行开发
  • 对框架新增特性功能但比较复杂,会延后几个版本制定相应的计划后进行开发
  • 与框架设计理念不太相符,或超出权限认证范畴,将会视需求人数决定是否开发

参与贡献
