我有两个:本地主机上的 STS 服务器和 Spring Web 应用程序。它奏效了。我已经测试了 OAuth2 授权代码授予流程 - 完全正常工作。
我将 STS 移到其他机器上，Web 应用程序在获取访问 token 时出现问题 - 完整跟踪(从 STS 重定向后停止/错误；刚开始从以下位置获取 token :https://sts-machine/authz/oauth2-resource/oauth/token 端点；停止访问 url:https://localwebapp:7443/swd/webLogin?code=306b88903d394f0b8145b2e8035fd306&state=PtTrt8) :
SEVERE: Servlet.service() for servlet [swdServlet] in context with path [/swd] threw exception
error="access_denied", error_description="Error requesting access token."

因此，当 webapp 尝试从以下访问 token 交换“代码”时会重置连接:
https://sts-machine/authz/oauth2-resource/oauth/token 。有趣的事实:手动发出请求效果很好! (手动交换访问 token 的代码)使用 Chrome 应用程序“Advanced Rest Client Application”和“Fiddler”请求编写器进行测试。
我使用wiresharks嗅探了两台机器。两者的结果相同 - 截图:http://i.imgur.com/2AYstN0.png(其中:10.1.0.121 是 localwebapp 机器，而:10.1.0.80 是 sts-machine)
为什么会出现连接重置？
有关配置的详细信息:
localwebapp:在 tc Pivotal Server(有点像 Tomcat)上运行，Win 8.1
sts-machine:是 IIS 上的 Thinktecture 授权服务器，Win Server 2012

我发现的是:
openssl s_client -connect sts-machine:443 不起作用，但是:openssl s_client -connect sts-machine:443 -servername sts-machine 确实有效!这表明 Java 客户端上的 SNI 存在问题。试图解决设置系统属性的问题: jsse.enableSNIExtension 到 true ，但没有任何成功... 如何强制 JVM 使用 SNI？ 最佳答案
您能指定您使用的是哪个 Spring 版本吗？
我们今天与 SNI 错误作斗争，解决方案是:
* 升级到 commons/httpclient 4.3.2+(我们使用 4.3.5)
* 重要的!将 DefaultHttpClient 替换为 HttpClientBuilder，因为 DefaultHttpClient 仍随 httpclient 4.3.x 一起提供，但不支持 SNI
关于java - SSL/TLS 连接重置 - 如何强制 Java 客户端使用 SNI？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/27780959/
