Spring Cloud云架构 - SSO单点登陆之OAuth2.0 根据token获取用户信息(4)

上一篇我根据框架中OAuth2.0的使用总结，画了SSO单点登陆之OAuth2.0 登出流程，今天咱们看一下根据用户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，咱们会在后面的文章中详细贴出全部代码供你们参考，并且会从建立数据库，到执行操做的每个流程记录下来。

从如今开始，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，你们来一块儿探讨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
