Spring Boot + JWT整合单点登录
|
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），关注公众号码猿技术专栏获取更多面试资源，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，关注公众号码猿技术专栏获取更多面试资源，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。 四、SpringSecurity整合JWT1.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！关注公众号码猿技术专栏获取更多面试资源 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。关注公众号码猿技术专栏获取更多面试资源 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  2.1父工程创建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；关注公众号码猿技术专栏获取更多面试资源 org.springframework.boot spring-boot-starter-parent 2.1.3.RELEASE 123456 2.2公共工程创建然后创建一个common工程，其他工程依赖此系统  导入JWT相关的依赖 io.jsonwebtoken jjwt-api 0.10.7 io.jsonwebtoken jjwt-impl 0.10.7 runtime io.jsonwebtoken jjwt-jackson 0.10.7 runtime com.fasterxml.jackson.core jackson-databind 2.9.9 org.springframework.boot spring-boot-starter-logging joda-time joda-time org.projectlombok lombok org.springframework.boot spring-boot-starter-test 123456789101112131415161718192021222324252627282930313233343536373839404142创建相关的工具类  Payload /** * @program: springboot-54-security-jwt-demo * @description: * @author: 波波烤鸭 * @create: 2019-12-03 10:28 */ @Data public class Payload { private String id;
