我对 Spring Social Twitter 有一些问题，最终还有更多问题，但我不知道如何识别问题所在。
我有一个带有 RestControllers 的简单应用程序。在前端用户可以单击“更新”并使用 ajax 我得到请求进行一些更改。此时，我想查看 Twitter 用户个人资料以获取有关关注者或推文数量的一些信息。这是基本的。我试着用 Spring Social Twitter 来做。现在我几乎没有问题。
这是我的代码（带有 pom.xml、configs 等）。：https ://github.com/mrcwojcik/tt-reports/tree/feature/fileservice
我拥有所有消费者密钥和令牌。应用程序此时在本地主机上。当我运行我的应用程序时，我在 Intellij 中得到了这个异常：

当用户想要执行简单的获取请求时，我也得到了一个奇怪的想法：CORS 策略已阻止从源“null”访问“ http://localhost:8080/twitterReports_war_exploded2/api/update/ ”处的 XMLHttpRequest：请求的资源上不存在“Access-Control-Allow-Origin”标头。
这很奇怪，因为在配置中我用 cors 做了一些事情。
