java - 文件夹绑定(bind) MsExchange 失败

Question

以下代码从最后一行开始出现错误。怎么了？我该如何修复它？

我的代码:

service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
service.setUrl(new URI(getDomain()));
ExchangeCredentials credentials = new WebCredentials(emailUsername, emailPassword, getDefaultCredentials());
service.setCredentials(credentials);
System.out.println("Authorize Ms exchange OK");
Folder folder = null;
folder = Folder.bind(service, WellKnownFolderName.Inbox);

由于不熟悉 Java 环境中的 EWS，我只能提供猜测。该异常提示证书路径，因此我认为您的应用程序由于证书信任问题而无法获得与 Exchange 的 TLS 连接。您可以在运行程序的同一机器上通过 HTTPS 浏览到 OWA 吗？
