Question

我正在使用https://github.com/OfficeDev/ews-java-api/提供的ews-java-api。虽然代码完全可以从我的本地运行，但在我们的服务器上运行时，我得到以下异常。来自服务器的URL的卷曲命令完美地运行。因此网络团队排除了防火墙问题。

以下是完整的堆栈跟踪

我甚至尝试过设置代理，代码是非常基本的文档中给出的示例。我们正在连接到https URL，正如我从文档中看到的那样，所需的代码已经内置在api中。我还尝试将证书添加到java密钥库。但没有任何帮助。有人可以帮助确定问题的原因吗？

部分代码在

之下

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
ExchangeCredentials credentials = new WebCredentials("xxxx", "xxxx","xxxx");
service.setCredentials(credentials);
service.setWebProxy(new WebProxy("proxyhost", proxyport));
service.setUrl(new URI("our exchange url"));

ews-java-api java.net.ConnectException：https的连接超时
