授权代码流程经过以下步骤。

客户端准备一个包含所需请求参数的身份验证请求。
客户端将请求发送到授权服务器。
授权服务器对最终用户进行身份验证。
授权服务器获得最终用户同意/授权。
授权服务器使用授权码将最终用户发送回客户端。
客户端使用令牌端点处的授权码请求响应。
客户端收到响应正文中包含 ID Token 和 Access Token 的响应。
客户端验证 ID 令牌并检索最终用户的主题标识符。

# 访问 http:localhost:8080 跳转至index页面 点击 Authorization Code 发起授权码登陆流程

1.由OAuth2AuthorizedClientArgumentResolver#resolveArgument 解析 @RegisteredOAuth2AuthorizedClient注解 组装 OAuth2AuthorizeRequest
2.OAuth2AuthorizedClientManager#authorize 将 OAuth2AuthorizeRequest 转换为 OAuth2AuthorizationContext 
3.OAuth2AuthorizedClientProvider#authorize 调用 
    OAuth2AccessTokenResponseClient#getTokenResponse 向授权服务器发起请求 `http://localhost:9000/oauth2/token`获取 OAuth2AccessTokenResponse
    并将OAuth2AccessTokenResponse 回填至 OAuth2AuthorizedClient参数中
4.然后使用webclient将获取到的OAuth2AuthorizedClient作为请求参数调用资源服务器
