我尝试通过spring-social连接twitter，但我得到一个无法解决的奇怪异常。
正如我所想，Spring-social正确地添加到应用程序中。当用户应该被重定向到twitter auth页面时，我会在ConnectSupport.class中获得异常：
private OAuthToken fetchRequestToken(NativeWebRequest request, MultiValueMap<String, String> requestParameters, OAuth1Operations oauthOperations) {
if (oauthOperations.getVersion() == OAuth1Version.CORE_10_REVISION_A) {
return oauthOperations.fetchRequestToken(callbackUrl(request), requestParameters);
}
return oauthOperations.fetchRequestToken(null, requestParameters);
}
堆栈追踪：

此外，我还有一个应用程序使用spring-social，它基于spring-boot，并且所有“社交”操作都运行良好。
两种情况下的请求和其他参数都是相似的。
起初，我认为代理的问题，可能是这些应用程序中的不同代理配置，但它也很好。我可以向外国网络应用程序发送请求。
感谢您的帮助，我的想法已经结束了。
