整合spring cloud雲架構 - SSO單點登陸之OAuth2.0 根據token獲取用戶信息(4)

上一篇我根據框架中OAuth2.0的使用總結，畫了SSO單點登陸之OAuth2.0 登出流程，今天咱們看一下根據用戶token獲取yoghurt信息的流程：

/** 
 * 根據token獲取用戶信息 
 * @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);  
    }  
      
}  
複製代碼

我這裏只是簡單寫了一些登出的代碼，咱們會在後面的文章中詳細貼出全部代碼供你們參考，並且會從建立數據庫，到執行操做的每個流程記錄下來。Spring Cloud大型企業分佈式微服務雲架構源碼請加企鵝求求一七九一七四三三八零

從如今開始，我這邊會將近期研發的spring cloud微服務雲架構的搭建過程和精髓記錄下來，幫助更多有興趣研發spring cloud框架的朋友，你們來一塊兒探討spring cloud架構的搭建過程及如何運用於企業項目。
