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：

    @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)){

        }  
          
        OauthAccessToken oauthAccessToken = userMgrService.getOauthAccessToken(accessToken);

           @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);  
        }  
          
    }

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。Spring Cloud大型企业分布式微服务云架构源码请加企鹅求求一七九一七四三三八零

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。
