上一篇我根据框架中OAuth2.0的使用总结，画了SSO单点登录之OAuth2.0 登出流程，今天我们看一下根据用户token获取yoghurt信息的流程：
/** * 根据token获取用户信息 * @param accessToken * @return * @throws Exception */ @RequestMapping(value = "/user/token/{accesstoken}", method = RequestMethod.GET) public ResponseVO getUserByToken(@PathVariable(value = "accessToken", required = true) String accessToken,@RequestHeader(value = "userId", required = true) Long userId) throws Exception { if(StringUtils.isEmpty(accessToken)){ return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_REQ_CANNOT_EMPTY, null); } OauthAccessToken oauthAccessToken = userMgrService.getOauthAccessToken(accessToken); if(null == oauthAccessToken){ return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_OAUTH_ACCESSTOKEN_EMPTY, null); } String userName = oauthAccessToken.getUserName(); if (StringUtils.isEmpty(userName)) { return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_OAUTH_ACCESSTOKEN_EMPTY, null); } return this.getUser(userName); } @RequestMapping(path = "/user/get/{userName}", method = RequestMethod.GET) public ResponseVO getUser(@PathVariable(value = "userName") String userName) { Map<String, Object> returnData = null; try { User user = userMgrService.getUserByName(userName); if (null != user) { returnData = new HashMap<String, Object>(); returnData.put("user", user); return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_SUCCESS, returnData); } return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_SYSTEM_ERROR, null); } catch (Exception e) { return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_SYSTEM_ERROR, null); } } 复制代码我这里只是简单写了一些登出的代码，我们会在后面的文章中详细贴出所有代码供大家参考，而且会从创建数据库，到执行操作的每一个流程记录下来。
从现在开始，我这边会将近期研发的spring cloud微服务云架构的搭建过程和精髓记录下来，帮助更多有兴趣研发spring cloud框架的朋友，大家来一起探讨spring cloud架构的搭建过程及如何运用于企业项目。完整项目的源码来源 技术支持求求1791743380
