SSL/TLS连接重置-如何强制Java客户端使用SNI？

我有两个：一个STS服务器和一个本地主机上的SpringWeb应用程序。它成功了。我已经测试了OAuth2授权代码授权流-完全正常

我将STS移到了另一台机器上，web应用程序在获取访问令牌（完整跟踪）时出现了问题（从STS重定向后停止/出错；刚开始从以下位置获取令牌：

https://sts-machine/authz/oauth2-resource/oauth/token

endpoint；在访问url时停止：

https://localwebapp:7443/swd/webLogin?code=306b88903d394f0b8145b2e8035fd306&state=PtTrt8

）：

因此，当webapp尝试从以下位置交换访问令牌中的“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！（手动交换访问令牌的代码）使用Chrome应用程序“高级Rest客户端应用程序”和“Fiddler”请求生成器进行测试

我使用wiresharks嗅探了这两台机器。两台机器上的结果相同-屏幕截图：（其中：10.1.0.121是localwebapp机器，10.1.0.80是sts机器）

为什么要重置连接？

有关配置的详细信息：

localwebapp：运行在tc Pivotal服务器（类似Tomcat）上，Win 8.1

sts机器：Thinktecture授权服务器是否位于IIS上，Win Server 2012

更新1 我发现：

openssl s_客户端-连接sts计算机：443

不工作，但：

---

openssl s_客户端-连接sts机器：443-servername sts机器

可以工作！这表明Java客户端上存在问题。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？您可以指定哪一个您正在使用的ch Spring版本？ 我们今天与SNI漏洞进行了斗争，解决方案是： *升级到commons/httpclient 4.3.2+（我们使用4.3.5）

---

*重要提示！将DefaultHttpClient替换为HttpClientBuilder，因为DefaultHttpClient仍然随httpclient 4.3.x提供，但不支持SNI。我遇到了相同的问题，也有一个旧版本的httpclient。我将Java从1.8.0_92升级到1.8.0_241，问题得到了解决。

当我将地址更改为不带SSL的地址时（HTTP而非HTTPS）：

http://sts-machine/authz/oauth2-resource/oauth/token

一切正常。因此我假设SSL/TLS层存在问题。我试图通过设置JAVA_OPTS=-Dhttps.protocols=“TLSv1，TLSv1.1，TLSv1.2”-Djdk.TLS.client.protocols=“TLSv1，TLSv1.1，TLSv1.2”来强制Tomcat至少使用TLSv1在server.xml SSL连接器中，我设置了sslEnabledProtocols=“TLSv1，TLSv1.1，TLSv1.2”。但https连接仍出现错误500…知道吗？SNI仅从Java 7提供，您正在运行该版本吗？您应该启用JSSE调试输出。刚刚与jinfo进行了检查：

Java.runtime.version=1.7.0_60-b19

因此默认情况下应启用SNI。我使用

-Djavax.net.debug=SSL、握手、信任管理器

optio运行服务器n、 这导致了。我还使用了简单控制台，jre7和jre8也有同样的问题。当我在我的代理（nginx）中强制TLS时，我也有同样的问题。启用SSL调试时，或多或少都是相同的stacktrace。您发现了更多信息吗？不幸的是，这对我来说仍然是一个未解决的问题。我没有找到合适的解决方案。因为在IIS上，我只有一个网站，所以我在服务器端禁用了SNI选项，所以JVM（“客户端”）不使用它。
