MINUTES); if (state == null || ! redisService. hasKey("oauth:github:state:" + state)) { redisService. set("oauth:token:code" + tokenCode, loginVo, 30, TimeUnit. SECONDS); String redirectUrl = githubOAuthProperties. getFrontendCallbackUrl() + "? code=" + tokenCode; LoginVo loginVo = (LoginVo) redisService. get("oauth:token:code" + code); redisService参考：https://dev. to/yyt0901/common-dependency-configuration-for-spring-boot-354-java-1721-1li7 （CTRL + F to search redisService in website） if (sysUser == null || sysUser. getStatus() == 0) { sysUser. setNickname(githubUser. getName() ! = null ? githubUser.
