整合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);  
    }  
      
}

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。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。
