概述
最后会附上源码
这篇介绍了一个项目中使用的双token登录认证刷新的demo,如需移植到生产项目中,需要根据实际情况做修改。
有个地方需要注意: 我这里刷新产生新的refreshToken时 旧的refreshToken并没有失效,如果不是特别敏感这点的话可以不计较,若是在意的话,那需要自己处理:比如用缓存记录失效的token每次token认证判断是否是失效的token ,如果是的话就返回验证失败。
下面代码中会用到本地redis缓存,如果没有安装或不会用,看下我之前的博文
win7_64 redis下载安装启动服务
springboot集成redis,redis工具类
spingboot redis demo源码
如果对token还不是很了解 , 那么建议先看个我之前写的用java标准处理token的库jwt 实现的一个简单token的生成、认证过程 demo:
基于JWT规范的JWS实现token认证过程,采用JWT库jose4j,附springboot项目 demo源码下载
如果对双token accessToken refreshToken时长设置以及刷新问题 不清楚的可以看下
双token刷新、续期,access_token和refresh_token实效如何设置

本地生成keyPair,本地运行AuthorizationService main方法生成keyPair 覆盖代码中的keyId、privateKeyStr和publicKeyStr。 如果不是泄漏了不用更换.
启动项目
1 先启动本地 redis 服务
2 启动token demo程序
测试
测试工具 Postman
1 注册
Postman 新建访问 http://127.0.0.1:8081/register?account=zhangsan&password=123456
2 登录
Postman GET方式 访问 http://127.0.0.1:8081/login?account=zhangsan&password=123456
注意 ,为了快速测试, 我特意将 accessToken 过期时间设置1分钟,refreshToken过期时间3分钟
3 查询用户信息 (用accessToken)
Postman GET方式 访问 http://127.0.0.1:8081/user/{accessToken}
-
登录后1分钟内 查询user信息
-
登录后1分钟40秒 查询user信息 (1分30内 accessToken都是有效的,原因解析token设置了 setAllowedClockSkewInSeconds(30),token过期了还能延长30秒有效 )
返回提示 accessToken过期,这时客户端需要 调用刷新accessToken接口(不要跳转登录页面)
4 刷新accessToken (用refreshToken)
Postman GET方式 访问 http://127.0.0.1:8081/accessToken/refresh/{refreshToken}
-
登录后 2分钟之前 刷新accessToken
只有 accessToken 会被刷新,refreshToken虽然我返回了 但是值还是登录返回的refreshToken值 ,如下:
-
登录后 2分钟 到 3分钟 内 刷新accessToken
accessToken 和 refreshToken 都会被刷新,如下:
-
登录后 3分40秒 刷新accessToken
报错返回提示 refreshToken 过期,如下:
这时客户端 需要跳转到 登录页面重新登录
