springboot oauth 鉴权之——授权码authorization_code鉴权

 近期一直在研究鉴权方面的各种案例，这几天有空，写一波总结及经验。

第一步：什么是 OAuth鉴权

       OAuth2是工业标准的授权协议。OAuth2取代了在2006创建的原始OAuthTM协议所做的工作。OAuth 2.0关注客户端开发人员的简单性，同时为Web应用程序、桌面应用程序、移动电话和客厅设备提供特定的授权流。

     参考理解：  Oauth2.0     理解OAuth 2.0     QQ授权      微信授权

第二步：什么是授权码模式

        授权码模式（authorization code）是功能最完整、流程最严密的授权模式。它的特点就是通过客户端的后台服务器，与"服务提供商"的认证服务器进行互动。

第三步：授权码授权流程

        

交互步骤： 
  （A）用户访问客户端，后者将前者导向认证服务器。
 
  （B）用户选择是否给予客户端授权。

  （C）假设用户给予授权，认证服务器将用户导向客户端事先指定的"重定向URI"（redirection URI），同时附上一个授权码。

  （D）客户端收到授权码，附上早先的"重定向URI"，向认证服务器申请令牌。这一步是在客户端的后台的服务器上完成的，对用户不可见。

  （E）认证服务器核对了授权码和重定向URI，确认无误后，向客户端发送访问令牌（access token）和更新令牌（refresh token）。

第四步：授权码模式实践

 1)、  引入相关jar： 

<!--security  -->
<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-security</artifactId>
</dependency>

<dependency>
       <groupId>org.springframework.security.oauth.boot</groupId>
       <artifactId>spring-security-oauth2-autoconfigure</artifactId>
        <version>2.0.0.RELEASE</version>
</dependency>
<!-- 使用lombok优雅的编码 -->
