本文我们来看下 SpringSecurity + JWT 实现单点登录操作,本文 2W 字,预计阅读时间 30 min,文章提供了代码骨架,建议收藏。
一、什么是单点登陆
单点登录(Single Sign On),简称为 SSO,是目前比较流行的企业业务整合的解决方案之一。SSO的定义是在多个应用系统中,用户只需要登录一次就可以访问所有相互信任的应用系统
二、简单的运行机制
单点登录的机制其实是比较简单的,用一个现实中的例子做比较。某公园内部有许多独立的景点,游客可以在各个景点门口单独买票。
对于需要游玩所有的景点的游客,这种买票方式很不方便,需要在每个景点门口排队买票,钱包拿 进拿出的,容易丢失,很不安全。
于是绝大多数游客选择在大门口买一张通票(也叫套票),就可以玩遍所有的景点而不需要重新再买票。他们只需要在每个景点门 口出示一下刚才买的套票就能够被允许进入每个独立的景点。
单点登录的机制也一样,如下图所示,
用户认证:这一环节主要是用户向认证服务器发起认证请求,认证服务器给用户返回一个成功的令牌token,主要在认证服务器中完成,即图中的认证系统,注意认证系统只能有一个。
身份校验:这一环节是用户携带token去访问其他服务器时,在其他服务器中要对token的真伪进行检验,主要在资源服务器中完成,即图中的应用系统2 3
三、JWT介绍
概念说明
从分布式认证流程中,我们不难发现,这中间起最关键作用的就是token,token的安全与否,直接关系到系统的健壮性,这里我们选择使用JWT来实现token的生成和校验。
JWT,全称JSON Web Token,官网地址:https://jwt.io,是一款出色的分布式身份校验方案。可以生成token,也可以解析检验token。
JWT生成的token由三部分组成:
头部:主要设置一些规范信息,签名部分的编码格式就在头部中声明。
载荷:token中存放有效信息的部分,比如用户名,用户角色,过期时间等,但是不要放密码,会泄露!
签名:将头部与载荷分别采用base64编码后,用“.”相连,再加入盐,最后使用头部声明的编码类型进行编码,就得到了签名。
JWT生成token的安全性分析
从JWT生成的token组成上来看,要想避免token被伪造,主要就得看签名部分了,而签名部分又有三部分组成,其中头部和载荷的base64编码,几乎是透明的,毫无安全性可言,那么最终守护token安全的重担就落在了加入的盐上面了!
试想:如果生成token所用的盐与解析token时加入的盐是一样的。岂不是类似于中国人民银行把人民币防伪技术公开了?大家可以用这个盐来解析token,就能用来伪造token。这时,我们就需要对盐采用非对称加密的方式进行加密,以达到生成token与校验token方所用的盐不一致的安全效果!
非对称加密RSA介绍
基本原理:同时生成两把密钥:私钥和公钥,私钥隐秘保存,公钥可以下发给信任客户端
私钥加密,持有私钥或公钥才可以解密
公钥加密,持有私钥才可解密
优点:安全,难以破解
缺点:算法比较耗时,为了安全,可以接受
历史:三位数学家Rivest、Shamir 和 Adleman 设计了一种算法,可以实现非对称加密。这种算法用他们三个人的名字缩写:RSA。
1.认证思路分析
SpringSecurity主要是通过过滤器来实现功能的!我们要找到SpringSecurity实现认证和校验身份的过滤器!
回顾集中式认证流程
用户认证:使用UsernamePasswordAuthenticationFilter
过滤器中attemptAuthentication
方法实现认证功能,该过滤器父类中successfulAuthentication
方法实现认证成功后的操作。
身份校验:使用BasicAuthenticationFilter
过滤器中doFilterInternal
方法验证是否登录,以决定能否进入后续过滤器。
分析分布式认证流程
用户认证:
由于分布式项目,多数是前后端分离的架构设计,我们要满足可以接受异步post的认证请求参数,需要修改UsernamePasswordAuthenticationFilter
过滤器中attemptAuthentication
方法,让其能够接收请求体。
另外,默认successfulAuthentication
方法在认证通过后,是把用户信息直接放入session就完事了,现在我们需要修改这个方法,在认证通过后生成token并返回给用户。
身份校验:
原来BasicAuthenticationFilter过滤器中doFilterInternal方法校验用户是否登录,就是看session中是否有用户信息,我们要修改为,验证用户携带的token是否合法,并解析出用户信息,交给SpringSecurity,以便于后续的授权功能可以正常使用。
2.具体实现
为了演示单点登录的效果,我们设计如下项目结构
因为本案例需要创建多个系统,所以我们使用maven聚合工程来实现,首先创建一个父工程,导入springboot的父依赖即可。
