如何使其余端点用于Facebook授权令牌验证以及如何使新用户和登录Spring Boot

Question

我正在开发一个应用程序，其前端是使用React.js编写的，后端REST API是使用Spring框架编写的。我想将社交登录信息添加到我的网站，因此经过数天的搜索和研究，我了解到OAuth2是解决方案。我知道前端应该处理从资源服务器（此处为Facebook）获取授权令牌的工作，而后端（java）应验证该令牌并与Facebook连接以获得访问令牌。然后，该访问令牌应与用户详细信息（例如电子邮件）一起存储在我的数据库中。

这是我的要求，一旦用户单击“通过Facebook继续”按钮，我的应用程序应使用详细信息-电子邮件和姓名（注册功能）在我自己的数据库中创建该帐户。之后，每当他们再次单击该按钮时，他们将登录并没有注册。其他网站的处理方式。

到目前为止，我的应用程序中已有该按钮，这使我从Facebook获得了授权令牌。

有人可以指导我在这里走的路吗？

此外，对于某些错误处理，我应该特别注意。
