Java 连接拒绝通过spring social连接Twitter

我试图通过SpringSocial连接twitter，但我遇到了一个奇怪的异常，无法解决。 正如我所想，SpringSocial正确地添加到了应用程序中。当用户应该被重定向到twitter身份验证页面时，我在

ConnectSupport.class

中遇到异常：

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);              
}

另外，我还有一个应用程序使用SpringSocial，它基于SpringBoot，所有“social”操作都运行良好

两种情况下的请求和其他参数类似

起初，我认为代理的问题可能是这些应用程序中的代理配置不同，但也很好。我可以将请求发送到国外的web应用程序

---

非常感谢您的帮助，我的想法已经结束。

我认为您已经按照Twitter上的所有说明，允许您的应用程序代表用户请求数据了？您提供的回调URL是否正确？您是否使用了正确的应用程序密钥？假设错误是“连接被拒绝”，我会首先假设其中一个配置不正确。@Steve，回答你所有的问题“是”。有了这个twitter应用程序，我的另一个项目也可以使用类似的配置。两个应用程序的回调URL都是相同的，这似乎有点奇怪。或者这就是你提到代理配置可能的原因吗？在twitter应用程序回调url中，我在一个端口上运行应用程序（而不是在同一时间：）。。。在最常见的问题是代理之前，在我向jvm添加代理属性之前，我遇到了相同的异常
